Shakespeare in Pakistan

shakespeare.jpgMake yourself comfortable, as this blog is unusually long -- even by my standards

The first World Health Organization team is on the ground and working in Peshawar province in northwest Pakistan.  And barely within hours of the arrival of the advance team, declarations were made and assurances were given that things were not as bad as first thought.

But Shakespeare also deplaned in Pakistan, accompanying the WHO team to the microphones.  First, the stories on the arrival of the WHO.  This is from Pakistani newspaper The News:

WHO team visits families of bird flu victims
By Mushtaq Yusufzai
12/19/2007

PESHAWAR: A team of the World Health Organisation experts on Tuesday visited the NWFP where they visited the Khyber Teaching Hospital and also met the ill-fated family of two young students who died of bird flu virus in October.

Also, a WHO technical team is also arriving Pakistan today (Wednesday) which, according to sources, would verify the results of bird flu victims diagnosed by the NIH Islamabad.

After their arrival, the WHO officials held talks with senior officials of the NWFP health department who told them of the situation in the province created after the bird flu virus.They went to the Khyber Teaching Hospital (KTH) where the two young brothers, Muhammad Idrees and Muhammad Ilyas, died on October 19 and 29 respectively mainly because of sheer negligence of the hospital administration, the NWFP health department as well as of the National Institute of Health (NIH), Islamabad.

In KTH, the WHO team arranged an informative workshop for doctors and nurses of the hospital, especially those dealing with bird flu patients.

Officials in the KTH told 'The News' the WHO team had brought Personal Protection Equipment (PPE) for the staff of the hospital.

The team also visited isolation rooms in the hospital where patients suffering from bird flu virus were admitted and advised the hospital administration to select some safe place at a distance from the rest of the hospital for keeping the bird flu victims, so that the virus could not spread in the hospital. It is very painful to mention here that in the entire province, there is not even a single isolation room for infectious diseases.

With the consultation of the WHO team, the KTH administration selected a separate portion in the hospital for keeping bird flu patients. There are 11 isolation rooms in the portion, which would accommodate 22 patients.

Acting Chief Executive KTH, Prof Dr Siddiqur Rahman, nominated Dr Mukhtiar Zaman Afridi as the head of a team that would handle bird flu related cases.

The WHO officials praised doctors and health workers of the KTH for their efforts, which the officials felt saved many lives. The team members said in the world so far 60 per cent of the bird flu patients died while the ratio in Pakistan, 35 per cent, was quite encouraging.

The team members later went to Tajabad town in Peshawar and met the family members of two young brothers died of the disease.

Note the October reference to the deaths, which we think was actually November 19 and 29, respectively.  But everything is up in the air these days, as we try to figure out if a brother is really a cousin, etc.  So let's stay loose on relatives, and dates of death for the time being.

Now a second report on the activity in the region, this time from Indian newspaper The Hindu.  All bolding is mine.

Experts comb Pak. for signs of human-to-human bird flu infection

ISLAMABAD, Pakistan (AP): A second team of health experts arrived in Pakistan on Wednesday to analyze samples from suspected bird flu cases to determine how the virus spread and whether human-to-human transmission may have occurred.

The experts from the US Naval Medical Research Unit No. 3 were expected to retest samples already gathered from a number of patients who were positive for the H5N1 bird flu virus in initial government analysis. Once the cases are confirmed, work will begin to piece together how the victims became infected.

"They are now investigating," said Orya Maqbool Jan Abbasi, spokesman for Pakistan's Health Ministry. ``The next day or two is very important.''

Four brothers were sickened last month in Abbotabad, north of Islamabad. Two died, one of whom was buried before tests were conducted. The other three tested positive for the virus. Up to six more people were suspected of being infected, including several who were in contact with poultry.

Outbreaks were reported among birds in the area before the human cases. However, Abassi stressed that there have been no new reports of bird flu in poultry or people.

A separate WHO team visited a hospital Tuesday in the northwestern city Peshawar that treated some of the patients. They were working with doctors and nurses on how to handle suspected cases and improve infection control measures.

``They want to go through the records in the hospital for the last month or two to see if there's been any upsurge in respiratory cases that weren't identified as H5N1 but which could actually be,'' said Gregory Hartl, a WHO spokesman in Geneva.

The team will look to see which patients could have been exposed to the virus by infected birds and also whether human-to-human transmission could have occurred.

One of the brothers who survived, Mohammed Ishtiaq, said he was hospitalized with flu symptoms after slaughtering chickens suspected of carrying bird flu without wearing protective clothing last month.

His brothers who died visited him in a hospital, he said.

Hartl said no new cases have been discovered, but increased awareness has led to more people with flu-like symptoms being checked.

``What this is showing is that they're taking everything very, very seriously,'' Hartl said. ``Surveillance has been enhanced, more people are reporting cases and more people have been sensitized on the heath care worker side of the need to notice.''

Pakistan has requested additional supplies of the antiviral Tamiflu as a precaution, Hartl said.

At least 209 people have died worldwide from the virus, which began plaguing Asian poultry stocks in late 2003, according to the WHO. It remains hard for people to catch, but scientists worry it could mutate into a form that spreads easily among people, potentially sparking a pandemic.

Associated Press medical writer, Margie Mason, contributed to this report from Hanoi, Vietnam.

But wait, according to WHO influenza head Dr. Keiji Fukuda, there is nothing extraordinary going on in Pakistan.  This story is from Reuters, dateline Islamabad (as was the above AP story), so we know for sure we have Mainstream Journalist Boots On the Ground!  I am bolding all Fukuda quotes and references.

WHO probes Pakistan's first bird flu death

By Augustine AnthonyTue Dec 18, 2:25 PM ET

Pakistani authorities and World Health Organisation experts were trying to determine on Tuesday whether bird flu had passed from human to human after the country reported its first human death from the virus.

But Pakistani and World Health Organisation (WHO) officials said there was no immediate cause for alarm and the United Nations agency was not raising its level of pandemic alert for the time being.

Pakistani health officials confirmed at the weekend that eight people had tested positive for the H5N1 bird flu virus in North West Frontier Province since late October, and one of the confirmed cases had died.

A brother of the dead man, who had not been tested, also died. It was not yet clear if he was a victim of bird flu.

Ministry of Health spokesman Orya Maqbool Jan Abbasi said the first man to catch avian influenza had been working culling poultry. He recovered but his brothers died.

Abbasi and other health officials said there was no suggestion of human to human transmission.

"Absolutely not," said Health Secretary Khushnood Akhtar Lashari. "The WHO is looking into all the things but whatever we have at the moment there's nothing to suggest that, remotely."

keiji%20fukuda.jpgThe global coordinator of WHO's influenza program, Keiji Fukuda, also said the eight cases are likely a combination of infections from poultry and limited person to person transmission due to close contact.

Fukuda said while unconfirmed, any human to human spread seemed similar to previous outbreaks in Thailand and Indonesia -- affecting close family members caring for sick loved ones, adding it was very reassuring that "we are not seeing large increases in the number of cases."

"It is definitely possible that we have a mixed scenario where we have poultry to human infection and possible human to human transmission within a family, which is not yet verified," he told Reuters in an interview.

Humans rarely contract H5N1, which is mainly an animal disease. Experts fear the strain could spark a global pandemic and kill millions if it mutates to a form that spreads more easily.

SECOND WHO TEAM

Lashari said the man who had been culling poultry might have inadvertently brought the virus back to his home, where his brothers fell sick.

"He took his equipment along and the suspicion is the virus was in the equipment he was carrying," Lashari said. "These are conjectures. It will be established when they do the sequencing test of the virus."

The area of the outbreak, near the towns of Mansehra and Abbottabad, about 60 km (40 miles) north of the capital, Islamabad, is in the foothills of the Himalayas. Partly forested slopes are dotted with villages and small chicken farms.

Abasi said 100 people with symptoms of flu living in the vicinity had been checked but all tested negative.

The last human case was reported on November 23, he said.

Of the seven people confirmed to be sick with avian influenza, six had recovered while one was being treated, a provincial health official said.

A three-member WHO team, joined by officials from the Pakistan National Institute of Health, traveled on Monday to Peshawar, the province's capital where the patients were treated. A second WHO team was due to arrive on Wednesday.

Authorities reported the last H5N1 virus case in wild birds in the area on November 30.

Bird flu first appeared in Pakistan in early 2006, and several outbreaks of H5N1 were reported this year.

The Pakistani cases bring to nearly 350 the number of people worldwide who are known to have contracted the H5N1 virus, which has killed more than 200 people since 2003.

Dr. Fukuda is a very well-respected doctor.  He is also with the WHO/UN, which means he is also a diplomat.  So parsing words is a unique talent; so is deciphering them.  Another Fukuda reference comes today from Reuters:

Mixed scenario seen behind Pakistan birdflu spread

By Stephanie NebehayTue Dec 18, 5:29 PM ET

The eight individuals in Pakistan who are suspected to have bird flu probably have a combination of infections from poultry and limited person-to-person transmission from close contact, a top World Health Organization expert said on Tuesday. Keiji Fukuda, coordinator of WHO's global influenza program, said while unconfirmed, any human-to-human spread seemed similar to previous outbreaks in Thailand and Indonesia -- affecting close family members caring for sick loved ones.

There was no immediate cause for alarm and the United Nations agency was not raising its level of pandemic alert for the time being, he said, adding it was very reassuring that "we are not seeing large increases in the number of cases."

"Right now it doesn't look like pure human to human transmission. It looks like the veterinarian, who was the index case, and a number of other suspect cases had poultry exposure," Fukuda told Reuters in an interview.

"It is definitely possible that we have a mixed scenario where we have poultry to human infection and possible human to human transmission within a family, which is not yet verified."

But human to human transmission "would not be particularly surprising or unprecedented," he added.

Eight people have tested positive for the H5N1 bird flu virus in North West Frontier Province since late October, and one of the confirmed cases has died. A brother of the dead man also died, but was never tested, so is not counted among them.

H5N1 is mainly an animal disease, but experts fear it could mutate into a form that could spread easily between people, causing a pandemic which could kill millions of people. In Thailand, a mother was killed by the virus in 2004 after cradling her dying infected daughter all night. The largest known cluster of human bird flu cases worldwide occurred in May 2006 in Indonesia's North Sumatra province, where as many as seven people in an extended family died.

Three WHO experts, led by Hassan El-Bushra of its regional Cairo office, is in Pakistan helping to investigate the outbreak.

The "index" case, who recovered, is a veterinarian who helped with culling operations and it is his two brothers who died after taking care of the ill man, according to Fukuda.

"This type of close contact we know can result in human to human transmission sometimes," he said.

"Right now, based on the information we have, the investigation going on and the feedback from the field team, we don't have anything pointing to push the alarm bells or increase the (pandemic alert) phase," he added.

The WHO uses a series of six phases of pandemic alert to gauge the level of threat. The world is currently in phase 3, a new influenza virus subtype is causing disease in humans, but is not yet spreading efficiently or sustainable among humans.

"In terms of public health implications, we are looking for human to human transmission where casual contact can lead to infections and allow big outbreaks in communities," Fukuda said.

A team from the U.S. Naval Medical Research Unit NAMRU-3 laboratory in Cairo was expected in Pakistan on Wednesday to carry out further tests on the samples from the suspect cases.

Gee, wonder where he got that "pushing the button" reference?  Or the need to reassure the planet that this is no reason to go to Phase Four?

There are three possible reasons:

1.  Dr. Fukuda reads this blog.  Highly unlikely.

2.  The mainstream media reads this blog, along with other blogs and Flusites such as FluTrackers and Flu Wiki.  They decided to probe the question of Phase Four based on reading blogs and flusites.  Or the media Googled the beejeesus out of the issue and found all the references.  Possible, even likely.

3.  The WHO is "leaning forward" on the issue of when to actually raise the threat level, and Dr. Fukuda was speaking what everyone in Geneva was thinking.  In other words, Dr. Fukuda, Dr. Margaret Chan and global influenza experts were thinking the exact same thing we were:  Is this the appropriate time to Push The Button?

This is the Most Likely Scenario, in my opinion.  

I want to zoom in on what Dr. Fukuda said as a guide for when we can expect Phase Four to be enacted.  Again, from the news story above:

"In terms of public health implications, we are looking for human to human transmission where casual contact can lead to infections and allow big outbreaks in communities," Fukuda said.
"Big outbreaks in communities?"  Is that when the WHO plans to go to Phase Four?  Don't they think that's a little late?  We know any raising of the pandemic threat level is necessarily tied to surveillance and transparency.  Pakistan is now translucent and surveillance is better.  We cannot say that was the case two months ago, obviously.  Nor can we say that is the case anywhere in sub-Saharan Africa, or within certain regions of Indonesia or China.    I hope Dr. Fukuda is not saying Phase Four is on the menu when an entire village or town is infected with sustained H2H H5N1 -- and the nation is neither transparent nor has adequate surveillance.  That might prove to be too late for all of us. 

So, back to the bard.  Why did he deplane in Pakistan?  The answer is complex yet simple.  Pakistan is wrestling with potential civil war, terrorism a la al Qaida and its leader Osama bin Laden (who may or may not be hiding in the same geographic region where all the flu stuff is taking place), huge public demonstrations and percolating civil unrest, and there is always that nuclear thing with India.  And as we all know, yesterday in southern Pakistan a train accident killed nearly 50 people. 

hamlet1-9704.jpgSo a nation with a shaky government and warring factions and a hostile neighbor and the world's Public Enemy #1 hiding within its borders -- well, they kind of need some good news for a change.  Good News would be defined in this context as the absence of really bad news.  And as we are seeing in the entire nation right now, there is High Anxiety among its people.  What if the WHO actually came out and said sustained H2H happened?  It is not inconceivable that Pakistan could reach the Tipping Point.  In global terms, that would be a really, really bad thing.

You have probably already guessed the Shakespeare line I am referring to.  It is from Hamlet.  Hamlet turns to Queen Gertrude and says,

"Madam, how do you like this play?"

Queen Gertrude replies, "The lady protests too much, methinks."

Let's just hope Hamlet's response is from the WHO's mouth to the world's ears:

"O, but she'll keep her word."

WHO, US Navy send teams to probe human bird flu clusters in Pakistan

2007%20dec-pakistani-brothers-mohammed-ishtiaq-right-and-mohammed-tariq-left-who.jpg

The two most famous survivors of H5N1 since Jones Ginting are pictured at left. 

Pakistani brothers Mohammed Ishtiaq, right, and Mohammed Tariq, left, who were treated for suspected H5N1 bird flu, come out from their house in Sukur village near Peshawar, Pakistan on Saturday, Dec. 15, 2007. Six people caught H5N1 bird flu in northern Pakistan last month and at least one person with the disease has died, the government said Saturday. The U.N. World Health Organization confirmed the deadly H5N1 strain was found in the six cases, but said a second round of tests were being carried out to make sure. (AP Photo/Mohammad Zubair)

The WHO has gotten their Boots on the Ground in Pakistan.  They are accompanied by top-flight staff from the world-famous US Navy research lab, headquartered in Cairo (NAMRU-3).  They are all charged with finding answers that may or may not ultimately invoke Phase Four on the Big Board. Specifically, the situation in Mansera and Peshawar, Pakistan, is growing more disconcerting, as some media reports are reporting that a third family cluster has arisen.  That third cluster of human cases would be the cousins of the many brothers infected (or suspected to have been infected) by H5N1.

To recap:  Pakistan has had anywhere from six to nine confirmed cases of human H5N1.  All indications -- from the onset of symptoms to the dates of death for the dead brothers -- point to classic human-to-human infection of Influenza A.  Two separate families are confirmed to be involved, and the third is awaiting confirmation.  Check my blog http://www.scottmcpherson.net/journal/2007/12/14/all-eyes-on-pakistan-as-h5n1-h2h-transmission-grows-more-pro.html

The two towns in question are very close together.  Flusite poster Hawkye has started a map pinpointing the locations of the clusters.  The site can be reached at: http://hawkeye00x00.awardspace.com/map/mapit.php?mapid=pakistan.xml . By the way, note the proximity of the two towns to the Tarbela Reservoir, a large body of water in the area.  

The topic now turns to determining just how many brothers are in this index family!  From what I can figure out, the brother at right in the photo above is the index case, Patient Zero if you will.  He is the veterinarian and helped in the culling of poultry in late October.  The brother (Jean Reno look-alike) at left also tested positive for H5N1.  Counting their two dead brothers, that would be four suspected cases and three confirmed cases in one single family.  No samples were taken of one of the two dead brothers, inexplicably.

Now to the day laborer/culler:  According to the Frontier Post (a Peshawar, Pakistan Newssite), the infected culler, his niece and another person are positive for H5N1, albeit less severe. That makes three more, which brings us to six comfirmed human cases of H5N1. 

The site also attempts to clear up the confusion surrounding patient Zero's US-resident brother, but adds some even more troubling news:

New York State health officials were informed Dec. 7 that a man from Nassau County who had returned from Pakistan told his doctor he might have been exposed to avian flu, said Claudia Hutton, director of public affairs for state department of health. The man went into voluntary quarantine at home, Hutton said. Then his son began developing flu-like symptoms. Samples from both man and his son were tested at state laboratories and at U.S. Centers for Disease Control and Prevention in Atlanta. CDC sent an airplane to Albany to pick up samples. The samples came back negative for H5N1 avian flu this week, and man and his son are no longer in quarantine, he said. He said there were erroneous reports on Internet that another brother of H5N1-infected family members in Pakistan returned to the U.S. and tested positive. The remaining suspected cases in Pakistan include a man and his niece, and a male who worked on a nearby farm. (bold mine)

Apparently, the reports of the CDC being Johnny-on-the-spot were wrong.  They were notified by the brother that he had traveled to Pakistan.  The CDC were not waiting for him on the tarmac, bunny suits at the ready.  The family doctor called the health department. Imagine for a moment if the two were asymptomatic carriers of H5N1.  Yeah, it scares the beejeesus outta me, too.  The newssite is at: http://www.thefrontierpost.com/News.aspx?ncat=hn&nid=640 with a big hat-tip to flusite poster Commonground.  The official New York State Department of Health press release regarding the sequence of events is available at: http://www.health.state.ny.us/press/releases/2007/2007-12-16_nassau_county_resident_tests_negative_for_bird_flu.htm with a hat-tip to flusite poster Dark Horse.

helen%20branswell.gifAnyway, the Canadian Press' Helen Branswell (photo) is also covering the situation, and one hopes the Canadians can cough up (no pun intended) the airfare to get her over there with an interpreter!  Ms. Branswell reports:

There was some confusion Saturday about how many people had tested positive for the virus, with Pakistan announcing six cases but an official of the World Health Organization suggesting as many as nine people may have tested positive for the virus in that country.

The WHO spokesperson said investigations are still under way to try to determine how the various people became infected, but some human-to-human spread is possible.

“We can't rule it out,” WHO spokesperson Gregory Hartl said from Geneva.

“There are other plausible explanations.... We don't know enough at this point. And in some of these cases, one never will know enough.” (bold mine)

http://www.theglobeandmail.com/servlet/story/RTGAM.20071215.wpakbirdflu1215/BNStory/International/home

My point exactly.  We may never know conclusively if this virus attained efficient H2H transmissibility in Pakistan.  But if medical authorities suspect it strongly, is that not evidence enough to press the button and move to Phase Four?  That is where the US Navy's NAMRU-3 unit comes in.  If anyone can find the answer quickly, they can.  They are remarkable.  To learn a quick tidbit about NAMRU-3, read my blog http://www.scottmcpherson.net/journal/2007/7/22/new-bird-flu-case-in-egypt.html .

Almost on que with my earlier post on the simultaneous threat of H2H H5N1, the WHO issued this statement:

WHO warns countries to be vigilant as bird flu flares in Asia

Monday, December 17, 2007

HANOI, Vietnam: The World Health Organization warned Monday that countries should be on alert for bird flu because it is again on the move, with Pakistan reporting new infections and Myanmar logging its first human case.

"The key to the public health response is surveillance," said Peter Cordingley, spokesman for the WHO Western Pacific region in Manila. "If we do actually get to the cases with antivirals early on, the health outcome is a lot better."

WHO experts arrived in Pakistan to try to sort out cases reported there, South Asia's first human infections. They were expected to visit a hospital and affected areas Tuesday, said WHO country representative Khalif Bile in Islamabad.

"They are here to get more information and to provide more support in the case of any potential risk," he said, adding that the Health Ministry, Agriculture Ministry and WHO are now working closely together following a "communication gap" when the government did not immediately report suspected cases to the WHO.

Four brothers and two cousins fell ill last month in Abbotabad, a small city north of Islamabad, while three others who slaughtered poultry in the same area and a nearby town tested positive for the H5N1 bird flu virus earlier this month.

Two of the brothers died, but specimens were collected from only one.

The cases were positive for H5N1 in initial government testing, but WHO will conduct further analysis to confirm the results.

WHO spokesman Gregory Hartl in Geneva said Sunday human-to-human transmission had not been ruled out, but added that poultry outbreaks had earlier been reported in the area and it was unclear if all patients had links to sick birds or infected surroundings.

A doctor who cared for the brothers also experienced mild flu-like symptoms, but more testing needs to be carried out to determine if she was infected, Hartl said.

Two poultry farms near Abbotabad have been closed and health workers are taking temperatures of those living in the affected area twice a day, but no new suspected cases have been reported, said Minhajul Haq, a district health officer.

"We are on high alert, though we still await any confirmation of human-to-human transmission," he said.

At least 208 people have died from the virus, which began plaguing Asian poultry stocks in late 2003. It remains hard for people to catch, but scientists worry it could mutate into a form that spreads easily among people, potentially sparking a pandemic.

With fresh poultry outbreaks reported in a number of countries, including Germany over the weekend, WHO urged nations to be vigilant in identifying and reporting cases in both birds and humans.

Myanmar's first human case was reported Friday in a 7-year-old girl who fell ill last month and survived, while Indonesia, the country hardest hit by the virus, has announced its 93rd death from the virus.

Two human cases were also recently confirmed in China, one of whom died.

The H5N1 virus often flares during the winter months. In some countries, like Indonesia, poultry outbreaks and human cases are reported year round, but many countries experience a flurry of activity when temperatures drop.

"It starts to pop at this time of the year, not just in this region where it's endemic, but it starts to appear in the West," Cordingley said. "Between now and April is a very dangerous time of the year."

Most human bird flu cases have been linked to sick birds, but experts suspect limited person-to-person transmission may have occurred in a few cases involving blood relatives. (bold mine)

Interesting that the WHO is now picking up the H2H mantra.  When dealing with risk communications, it is critically important to stay "on message" and not give mixed signals.  How many times have we watched with incredulity as a government, while trying to prepare its people for a flu pandemic, downplays the seriousness of a poultry outbreak of H5N1?

You cannot try to raise awareness and concern about an influenza pandemic, and then tell people a poultry outbreak is not a cause for alarm.  My God, two weeks ago the Polish were selling H5N1-tainted raw chicken and EGGS in their supermarkets!  Patting people on the back and reminding them that cooking poultry thoroughly will kill virus is of no consolation to some hapless sod who orders his eggs over easy and gets them runny in a Polish restaurant, or gets an accidentally undercooked chicken there.   

Transparency in the most unlikely of places

2007%20myanmar%20parade.jpgLike most flu watchers, I was struck by the seemingly contradictory behavior of the government in Myanmar last week.  Unless you live in your own universe where you are the deity, you are painfully aware of the situation regarding the military dictatorship's antipathy towards anything even remotely resembling freedom, democracy and transparency.  There are even hushed rumors that in the last round of anti-government demonstrations in that country (previously known as Burma) this past September and October, hundreds -- if not thousands -- of Buddhist monks were killed and (even more horrifying), there are allegations that several injured monks were cremated alive.  http://209.85.207.104/search?q=cache:YDx3ElhwIqsJ:www.globalvoicesonline.org/2007/10/02/myanmar-list-of-detainees-and-letter-from-a-88-generation-worker/+myanmar+government+priests+killed+2007&hl=en&ct=clnk&cd=3&gl=us

So what can scare one of the most repressive regimes in the world into calling the World Health Organization?

Bird flu.

One can only imagine the telephone call that took place.  Only Bob Newhart could do that call justice. 

"W.H.O. bird flu clearinghouse Geneva.  You want to report a suspected case?  Where are you calling from?

"You're kidding, right? This call is from Myanmar?  C'mon, who is this really?"

Anyway, a young girl came down with H5N1 bird flu last week, and before you could say "Gesundheit!" (by dictatorship standards), the Myanmar authorities had the WHO on the line . From the Miami Herald, via AP:

Myanmar reports 1st human bird flu case

The World Health Organization has confirmed Myanmar's first human case of bird flu and praised the secretive country for its quick and open handling of the infection.

The U.N. body and the country's health ministry found that a 7-year-old girl from Keng Tung in northeastern Myanmar had been infected with the deadly H5N1 virus, WHO said on its Web site Friday. She has since recovered.

The WHO hailed Myanmar's transparency and swift action in alerting outside health officials about the case. Myanmar's ruling junta has been under international fire since September for killing and arresting pro-democracy protesters, with dissident groups putting the death toll at about 200.

"They handled it very, very well," said Shima Roy, spokeswoman for the organization's regional office in New Delhi. "They actually did house-to-house surveillance, especially in the area where there had been an outbreak of avian influenza in poultry."

State media reported the girl was hospitalized on Nov. 27 and released on Dec. 12 in good condition after being treated with the antiviral drug Tamiflu.

Bird flu has recently resurfaced in parts of Asia, with human deaths reported in Indonesia and China and fresh outbreaks in poultry plaguing other countries during the winter months when the virus typically flares.

According to the WHO, there have been 340 cases of bird flu in humans worldwide since 2003 - 208 of them fatal.

Experts believe most human victims of the virus were infected through direct contact with sick birds. Although bird flu is difficult for humans to catch, experts fear it could mutate into a form that spreads easily among people and spark a flu pandemic.

The young victim, Nan Kham Than, was among four people suspected of having the virus during an outbreak of the disease in poultry in mid-November, the state-controlled New Light of Myanmar newspaper said. Laboratory tests confirmed that only the girl was infected.

The Health Ministry for 10 days closely monitored 689 persons who were involved in culling chickens or lived near the affected farms, and found that no other people were infected, the newspaper said.

Myanmar reported its first bird flu outbreak in March 2006 in the central part of the country, but until now had reported no human infections.

H5N1 began ravaging Asian poultry stocks in late 2003, leading to the death or slaughter of millions of birds.

http://www.miamiherald.com/news/world/AP/story/345709.html

Kudos to Myanmar for their swift reporting of the case and the equally swift transport of virus samples for analysis.  One step toward transparency, no matter how small, is cause for celebration.

It is sometimes worth remembering, however, that dictatorships have an easier time of controlling bird flu than democracies.  House-to-house searches are nothing new to an enslaved people. 

But it is worth noting that Myanmar did what Indonesia steadfastly refuses to do -- promptly notify the WHO and then equally promptly send virus samples to Geneva.

What a bitter irony it would be if the Indonesians continued their ridiculous withholding of virus samples until they had solid assurances that they would be first among equals for vaccine, and then the virus mutates in, say, Myanmar or Pakistan, and Indonesia has no leverage left because their samples were then worthless?  They would have mortgaged their peoples' lives for nothing -- not to mention the rest of the worlds'.  And they would be in the same spot they were in previously -- standing in line, waiting for whatever tablescraps were left.

No, I take that back.  they would be in a decidedly worse spot, because of the ill will they have generated with the industrialized world. 

All eyes on Pakistan as H5N1 H2H transmission grows more probable

2007%20dec%20pakistan%20cull.jpgThe confused jumble of media and medical reports coming out of Mansera, Pakistan is beginning to stabilize.  With that stabilization, we are beginning to get a picture of activity that is much more serious than originally assumed.

First, massive tips of the cap: The Flusites are absolutely nuclear with activity on this topic right now, with Flu Wiki and Flutrackers leading the way (you can click a link to them via this Website).  Dr. Henry Niman at recombinomics.com is doing his usual excellent job of sorting through the maze and reading between the lines.  Plus, all the A-list flubloggers -- Mike Coston, Crawford Kilian, SophiaZoe and others (just a click away via this site) -- are maintaining excellent lines of communication.

Distilled from all these sites and opinions and translations, here is what apparently has happened:

In one of the numerous Pakistani H5N1-related bird culls of the past few months, a veterinarian appears to have been exposed to the H5N1 avian flu virus last October.  Remember that date. He then, by all appearances, transmitted the virus to one or more of his brothers.  They died ten days apart, strongly suggesting a chain human-to-human transmission, precisely because of the lag times.  If the two sons were infected by, say, eating a diseased chicken at the same dinner table, or even as leftovers, the infection incubation period -- and therefore the deaths -- would have occurred much more closely together. 

But they didn't, and the timetable gets really scary here.  If the vet brother (A) gets infected in October during the cull, and one brother (B) dies on November 19 and the other brother (C) on November 29, there is reason to strongly suspect the infections were passed down like a daisy-chain.  Human to human.  Chain transmission. 

The next wrinkle is really something.  There was another brother (D) of the vet, and who is a resident of -- drum roll, please --  the United States!  He gets the word that brother B died November 19th, and goes home to Mansera, Pakistan.  He then manages to contract bird flu himself and tests positive for the disease.  After hospitalization and confirmed recovery, he returns to the Long Island, New York area.  Immediately upon his arrival at the airport in Nassau County, New York, local health authorities and the CDC immediately place him (D) in quarantine and test him thoroughly until it is determined he tests negative for H5N1 and is now safe to release.  Kudos to the CDC and the authorities in Nassau County, New York.  So the CDC can find people now!  That is a comforting fact.

So to recap: Four brothers (ABCD) are in the first cluster family, one a vet.  And that vet was, by newer media accounts, the sole person to expose himself to poultry during the cull.  Two brothers are now dead, and the remaining two have tested positive for H5N1.

At the same mass bird cull that the veterinarian attended, a day laborer also contracted H5N1.  He is in hospital.  the culler's daughter is either in the hospital with bird flu-like symptoms or simply under observation, depending on the accounts.  Family contacts of all infected are under observation and, one would hope, also under isolation.  .So a second potential cluster develops from the same cull.

All this sounds eerily similar to the outbreak of highly pathogenic H7N7 in the Netherlands in 2003.  As you recall, a veterinarian died in that outbreak, and human-to-human transmission was thoroughly documented by medical researchers (http://www.eurosurveillance.org/em/v10n12/1012-222.asp).  That study's abstract concluded:

Further seroprevalence studies among contacts of asymptomatic H7 cases should be conducted.

So we have as close to a confirmed familial cluster of H5N1 that we have witnessed since May, 2006 in Indonesia.  And we have another potential familial cluster with the culler/laborer.  There may be a third cluster, but I believe we are seeing the "fog of war" syndrome as the Pakistani press tries to sort out some erroneous and conflicting dates and test results.

Anyway, if we have two clusters or three, that is two to three too many for the Pakistani government to tolerate.  So today, the entire nation of Pakistan went on medical alert.  In a scene that reminds me of the end of Howard Hawks' classic The Thing from Another World, when the call "Watch the skies!  keep looking, keep watching the skies!" goes out via the wireless all over the world, local health departments in Pakistan are especially tasked with reporting ANY "untoward" situation.  They are clearly worried that, on this farm in Pakistan last October, Qinghai H5N1 (Clade 2.2) may have developed the capacity for efficient human-to-human transmission.

This should not surprise anyone in the least.   Who knows how many times since 2003, culling has prevented (or postponed) the Next Pandemic?  Go back to December, 1997, when then-Hong Kong health officer Dr. Margaret Chan may have saved the planet from a pandemic when she ordered the death of every bird in the city? At the risk of a bullet in the back of the head from her brand-new Communist Chinese handlers (Hong Kong passed from British to Chinese control in June, 1997), she made the decision to defy the totalitarian leaders and tell the truth.  As we know today, she runs the WHO.

I personally believe that the mutations necessary to change H5N1 to a lethal and efficient killer of humans can take place in multiple environments in multiple areas of the world at the same time.  These simultaneous "tipping points" are why we need to look at the Big Picture, rather than become focused merely on one flashpoint.  If chain H2H is happening in Pakistan, then right now, anywhere else on the planet H5N1 causes an outbreak in poultry, we now need to be extremely vigilant in our search for the presence of human clusters.  Everywhere.

push%20the%20buttonhumb--aa053957.jpgThe politics of going to Phase Four.

For the first time since H5N1 avian influenza has been tracked by the WHO, there is compelling evidence of simultaneous clusters of possible human-to-human transmission occurring in multiple nations with little physical proximity between them. 

Specifically, the locations are China, Indonesia and Pakistan.  In all three cases, people have died who were family members.  And what is equally distressing is that the third location -- Pakistan -- has previously never reported a confirmed case of human H5N1 infection.

We also know that on at least two different occasions within Indonesia, in the past 13 months, the WHO had vast quantities of Tamiflu distributed to thousands of villagers.  This was done in an attempt (so far successful) to prevent a cluster from growing into an outbreak.  Those two times were August, 2006 and September, 2007.  We all know of the August 2006 "blanket" of Tamiflu over four remote villages within a few clicks of each other; but we never heard about the results of the Palua Tabuan blanket.  Palua Tabuan is an island off the coast of Sumatra.  Every single villager on the island was given Tamiflu prophylactic ally last September as "fowl plague" and another undisclosed illness swept the island. 

Coupled with the simultaneous emergence of divergent familial clusters of H5N1-infected humans is the ongoing round of hostilities between the WHO and the Indonesian government.  Someone please tell me the difference between the Indonesian government's intransigence on the issue of sharing H5N1 virus samples and the Iranian government's refusal to cooperate on the topic of nuclear reactors.  Both situations are ticking time bombs that can spell doom for millions of innocent people if handled incorrectly.

bobby%20petrino.jpgOf course, we are more than willing to help out the Indonesian government when they come calling, as we did when it appeared Bali was fomenting H2H-capable bird flu last August and September.  By golly, the Indonesian government was more than willing to beg for help save the Global Warming Summit's location, hat in hand.  But once the virus had appeared not to mutate, the Indonesians assumed their previous defiant stance, with all the gratitude and credibility of Bobby Petrino.  I have dealt personally with Bobby Petrino, by the way, and I can tell you he is never to be believed and everything negative you ever heard about the man is probably true.  Now the entire nation knows his word is about as good as --well, as good as Mahmoud Ahmadinejad or Indonesian Health Minister Siti Fadillah Supari.

But I digress.  The point is, politics eventually comes into play, one way or another.  And the decision to raise the threat level from 3 to 4 will be a political one.

SWHO%20threat%20level%20phases.jpgo I ask, in light of the above factors:  Is it time to raise the threat level for pandemic influenza from Phase 3 to Phase 4? 

Is the Indonesian government's refusal to help the global preparedness effort not as big a threat as the virus itself?  Have we not seen that this virus is a mutating fool and is steadily acquiring the genetic characteristics of human influenzas?  Have we not seen at least empirical evidence of H2H (and H2H2H in Indonesia in May, 2006) over and over again?

Let's threaten Indonesia with raising the threat level, if for no other reason than to get Indonesia (and the rest of the world) off its rear end.  Here's what raising the threat level would do:

  • First, it would act as a catalyst for the governments of states, counties and cities to get moving with awareness and preparedness efforts.
  • Second, it would prompt the private sector to finish its preparation efforts.
  • Third, it would be a huge black eye to the economies of any nation that had an endemic bird flu problem and, for whatever reason, refused to take appropriate steps to contain or eradicate it.  Are you listening, Indonesia?  No more global conferences.
  • It would help activists like us to get our message out more clearly and to more people.
  • It would focus media attention on the issue.
  • And it would remind families that they need to prepare themselves for a pending viral disaster.

We need to adjust our thinking and discuss the theory that the virus will mutate spontaneously and simultaneously in different locations due to some external influence or recombination event.  And our ability to identify and isolate this emerging virus will be totally reliant upon the levels of communication and cooperation between sovereign nations and between those nations and the WHO.  This means I do not hold out much hope that the WHO threat level phases will be able to maintain any semblance of real-world, real-time correlation with actual, evolving events.

Look at the mobilization of the Chinese military in Nanjing, the province affected by the latest suspected H2H event.  The Chinese military is wasting no time as it considers the threat of avian influenza in the province to be as great as the threat from SARS in 2003-04 (http://www.newfluwiki2.com/showComment.do?commentId=76347) .  Additionally, guards have been set up around the building where the latest H5N1 victim is said to be recovering.  They are clearly not taking any chances.

In Tangerang, Indonesia, the situation is much more dire.  I have blogged no less than four times in the recent past regarding the presence of H5N1 in Tangerang.  Family clusters are not uncommon there.  Just this past week, a 28-year old woman and a 47-year old man have both died in Tangerang. Causes are listed as anything from handling manure (the woman was a plant seller) to raising ducks (the man).

How about the more obvious thing:  Something big is happening in Tangerang province, and it is calling out for the world to investigate?  I am quoting directly from Dr. Henry Niman's commentary on the latest developments on his Website, recombinomics.com:

The two confirmed cases above extend the cluster of H5N1 cases in Tangerang.  Four of the five most recent confirmed cases in Indonesia have been from Tangerang and all but one died.  This clustering increases pandemic concerns.  Sequences from most of the human cases this year have been withheld, so tracking of H5N1 evolution in humans in Indonesia is not currently possible.  Bird sequences from Indonesia match earlier cases, but the most recent public human sequences from January had additional divergence not well represented in the public bird sequences.

H5N1 in poultry and wild birds in Indonesia has been widespread, but the recent confirmed human cases have been concentrated in Tangerang, adjacent to Jakarta, or Riau province in central Sumatra.  These two geographic clusters suggest that H5N1 in these regions is more efficiently transmitted to humans and raise concerns about unreported cases.  The vast majority of cases in Indonesia are confirmed when the patient is in critical condition and the case fatality rate in Indonesia is above 80%.  This high rate raises concerns that milder cases are not being reported, raising additional concerns.

WHO Pandemic Phase 4 is defined as "Evidence of increased human-to-human transmission."  So what constitutes evidence?  Is it a dramatic upswing of localized human H5N1 cases in a nation where no one can get their hands on virus samples?  If we limit this decision solely to scientific analysis and examination, at the end of the day it will still be up to a consensus of scientists to give their subjective opinion.  I said opinion.  That means a bunch of people in a room (or via videoconference) trying to come to a group decision on what to call things.

Meanwhile, in several remote (and maybe not so remote) corners of the planet, the virus mutates and causes more clusters.  The possibility for this to happen is upon us.

Look at what is going on around the world, as we speak.  There are multiple outbreaks of H5N1 in poultry in Poland.  Egypt just went on alert against H5N1, and no one would ever fault the Egyptian government to be digging in against this foe.  China goes on alert. Vietnam continues to wrestle with outbreaks.  Pakistan culls poultry and then two humans die.  Indonesia has no earthly idea how entrenched the virus is there.  Russia culls hundreds of thousands of birds. Saudi Arabia is reporting new cases in poultry, as is Bangladesh.  South Korea and China are battling localized outbreaks in poultry. And we haven't even gotten halfway through December!

The single biggest thing the WHO can do to raise awareness of H5N1's pandemic potential is to raise the threat level -- now -- from Phase 3 to Phase 4.  I am certain they can find sufficient justification, if said justification does not exist already.
