A problem of Olympic proportions

 beijing2008_logo.jpgChina has a major problem looming on its horizon, and it is found at the intersection of the 2008 Summer Olympics and H5N1. Simply put, the Chinese know that any ill-timed outbreak of H5N1 in poultry -- coupled with any simultaneous human infections, particularly tourists and/or athletes -- could irreparably harm the nation's economy if it occurs during the run-up to the games, or, even worse, during the Games themselves.

H5N1 junkies may recall the outbreak of bird flu in poultry in northern China's Shanxi Province last summer. The outbreak -- almost certainly Clade 2.3, a.k.a. "Fujian" H5N1 -- happened in the center of a conglomerate of seven busy historic tourist centers. This accompanied a human case in fabled Guangdong Province, in south China near Hong Kong. The Chinese moved with great swiftness to put down the outbreak.

 china%20syndrome%20book2.JPGAll this activity set off what I call the Chinese government's "FDI Meter," FDI being the initials for Foreign Direct Investment. The Chinese learned from the SARS epidemic in 2003 that to deceive the world had disastrous economic consequences for the emerging economic power. As chronicled in Karl Greenfield's excellent SARS history China Syndrome (required reading for all influenza aficionados), China lost tens of billions of dollars virtually overnight. There were a number of very brave (braver than any of us, I assure you) Chinese doctors and political dissidents who dared leak the presence of a new and deadly virus to the world. Once the FDI exodus had begun, brand-new Chinese leader Hu Jintao had all the ammunition he needed to open up the nation's dialogue and also use SARS as the method of eliminating his predecessor Jiang Zemin's corrupt and old-line Party leaders, who were ultimately responsible for what I call Mayor Larry Vaughn Syndrome (Murray Hamilton's role in Jaws). Hu's ability to both open up his nation's true situation and simultaneously remove his potential political opposition was the first glimpse at his capabilities and ingenuity. Hu ain't no dummy.

So the CINO Chinese (Communist In Name Only) know, from previous experience, that the presence of a fatal disease, coupled with a clamp-down of media, spells economic TROUBLE.

Let's fast-forward to today's disclosure that in Guangdong Province, the Chinese are taking absolutely no chances. From the People's Daily Online:

150,000 Poultries Culled in Guangzhou Bird Flu Outbreak

China's southern city of Guangzhou has destroyed 153,320 domestic fowls in the wake of an outbreak of bird flu, local authorities said on Tuesday.

The extermination of 134,384 ducks, 18,786 chickens and 150 doves was carried out in nine villages within a radius of three kilometers from the site of the outbreak, an official with the Panyu district government said.

A total of 68 poultry farmers in Panyu district who have had close contact with ducks killed by bird flu have taken blood tests and medical checkups, and were found to be in good condition.

The Ministry of Agriculture and the National Avian Influenza Reference Laboratory have confirmed a subtype H5N1 bird flu strain killed 9,830 ducks raised in Sixian Village of Panyu District in Guangzhou City since September 5.

The Panyu district government announced on Tuesday the suspension of all poultry markets within a 13-kilometer-radius surveillance zone. Tan Yinghua, Party chief of the district, told Xinhua the district would put more pork, beef and fish on the market to meet the needs of local consumers.

As the world's largest producer of poultry, livestock and aquatic products, China has suffered huge economic losses from outbreaks of animal diseases. It is estimated that animal diseases cost China 40 billion yuan annually

The previous reported case of H5N1 bird flu in China occurred in May in central China's Hunan Province, which killed more than 11,000 poultry with another 52,800 birds being culled.

China has reported 25 human cases of bird flu since 2003, which have resulted in 16 deaths.

With 323 days to go before the Opening Ceremonies, expect more of these quick responses in the run-up to the 2008 Summer Olympics. And isn't it telling that you can get better avian flu information from a Communist Chinese press service than from 99% of the American news media? Maybe if OJ caught bird flu.... that would solve many problems!

Meteor aftermath sickens Peruvians

Having been raised on a steady diet of black and white 1950s-era science fiction movies, you will now understand my excitement at the following story (tempered by concern about the health of the villagers and authorities), courtesy of the Guardian Unlimited (UK):

cratery372.jpgPeru meteorite crash causes 'mystery illness'

A meteorite has struck a remote part of Peru and carved a large crater that is emitting noxious odours and making villagers ill, according to local press reports.

A fireball streaked across the Andean sky late on Saturday night and crashed into a field near Carancas, a sparsely populated highland wilderness near Lake Titicaca on the border with Bolivia, witnesses said.

The orange streak and loud bang were initially thought to be a plane crashing. When farmers went to investigate, however, they found a crater at least 10m wide and 5m deep, but no sign of wreckage.

The soil around the hole appeared to be scorched and there was a "strange odour", a local health department official, Jorge López, told Peru's RPP radio.

Later the farmers complained of headaches and vomiting. Police who went to investigate the crater were also stricken with nausea, prompting authorities to dispatch a medical team that reached the site today.

"The odour is strong and it's affecting nearby communities. There are 500 families close by and they have had symptoms of nausea, vomiting, digestive problems and general sickness," said Mr López.

At least 12 people were treated in addition to seven police officers who required oxygen masks and rehydration.

The farmers expressed fears that what appeared to be chunks of lead and silver around the site could contaminate the soil.

A member of the National Academy of Sciences, Modesto Montoya, told the state press agency that a fallen meteorite did not present any danger unless it hit some structure on impact.

"None of the meteorites that fall in Peru and make perforations of varied sizes are harmful for people, unless they fall on a house," he said. Another meteorite fell to Earth in Arequipa province in June.

Fowl vaccinations (apparently) fail again

Posted on Monday, September 17, 2007 at 10:23AM by Registered CommenterScott McPherson in | CommentsPost a Comment

MandarinDuckCAM.jpgThe Chinese disclosed this past weekend that some 30,000-plus ducks are headed for the incinerator and/or big burial pit in Guangdong Province.  Almost 10,000 ducks died between September 5 and 13 in Guangzhou's Panyu District and a sampling tested positive for H5 virus.  The authorities moved swiftly to contain the outbreak in poultry.  http://in.reuters.com/article/worldNews/idINIndia-29548020070915

But The Standard, a Hong Kong newspaper, is also reporting that at least 9,800 of those ducks in question had previously received a vaccination against the H5N1 virus!  Quoting from The Standard,

According to Guangdong Animal Epidemic Prevention Center director Yu Yedong, the 9,800 ducks that died at Sixian village had been vaccinated. But he added the first vaccination could only be 65 percent effective, while a second shot would have made it 90 percent.

He believed the birds were infected after the first shot. The deaths led to a mass culling of 32,600 ducks on Friday in an attempt to contain the outbreak.

Chinese bird flu vaccination attempts have been very controversial and have inadvertently put the entire world at risk of infection.  Just last year, the disclosures came that the Chinese government had mixed the M2 inhibitor Amantadine with its H5N1 poultry vaccine.  This. of course, led to H5N1's acquired resistance to Amantadine, the first antiviral used against influenza A some 20+ years ago.  Amantadine prevents influenza's M2 protein coat from dissolving. 

Just not any more: Seasonal influenza is Amantadine-resistant, but China's unwise mass use of the drug in chickens and ducks guaranteed that H5N1 would develop resistance prematurely.  So a front-line antiviral, cheap and plentiful, was summarily taken off the table by the Chinese.  Thanks, guys.  And we thought The Return of Lead Paint in Toys was bad!

Anyway, back to the story: The Guangdong ducks got the first shot, but were infected before the second shot could be administered.  So two things have happened:  First, these ducks only had a 65% chance of surviving an H5N1 attack.  According to the USDA, ducks are usually harvested between eight and sixteen weeks http://www.fsis.usda.gov/Fact_Sheets/Duck_&_Goose_from_Farm_to_Table/index.asp . So despite the vaccination, more than 65% of the vaccinated ducks (it's more like 98%) got sick and died. 

Second, H5N1 gains a measure of resistance to the vaccine; it is allowed to "drift" and mutate, which concerns Dr Ho Pak-leung, an infectious diseases expert at Hong Kong University.  He stated there were worries the virus had mutated or the vaccine had not been effective.   This either means the vaccine was ineffective, or the virus has drifted beyond the vaccine's ability to protect.  Either way, it is not good news.

H5N1 moves from wild birds to poultry and back again, with humans somewhere in between, depending on locale.  And as we all know, influenza is an extremely resilient and "smart" virus:  Pretty impressive for something that many scientists do not even want to classify as a life form!  The bottom line is that we can expect similar vaccination attempts to fail, as the virus gains intelligence in its RNA and drifts further.

BBC produces chilling documentary/dramatization

Posted on Friday, September 14, 2007 at 03:41PM by Registered CommenterScott McPherson in | Comments3 Comments | References21 References

pandemic_BBC%20photo.jpgOther bloggers have noted the appearance of the BBC pandemic influenza documentary/drama "Pandemic," part of its science series called "Horizons." Pity the show is not broadcast on BBC America, because it is the most chilling treatise on the subject of pandemic influenza that I have ever seen, and it needs to be seen by as many people as possible.  The link to the BBC Horizons Pandemic page can be found at: http://www.bbc.co.uk/sn/tvradio/programmes/horizon/broadband/tx/pandemic/ .

The entire 90-minute documentary can be seen at this link:

http://video.google.com/videoplay?docid=-7443717071229476088&q=pandemic+duration%3Along&total=73&start=0&num=10&so=0&type=search&plindex=5

Back to the show.  The program shifts between interviews with several scientists and healthcare professionals, while giving a fictional backstory about three individuals.  They are a Cambodian man at the wrong place at the decidedly wrong time; an American businessman returning from a Hawaiian meeting with Chinese counterparts; and a young British woman. 

The BBC writers splice in factual commentary from such experts as influenza rock star Dr. John Oxford in London; Dr. Gregory Poland, Professor of Medicine at the Mayo Clinic;  Dr. Jim Robertson of the UK's National Institute for Biological Standards and Control; and several other experts, including a doctor from Georgia (that's Georgia as in Go Bulldogs!).

Of all the commentary, Poland's and Oxford's are the most chilling.  Oxford has been doing influenza research for decades, and belongs to that too-small cadre of global experts that includes Dr. Robert Webster and Dr. Graeme Laver. john%20oxford.jpgOxford's comments can be savored via this program; his insight into the link between the 1918 pandemic and the subsequent pandemic of encephalitis lethargica (as shown in the film "Awakenings") is virtually bulletproof. Here is some advice from Oxford, directly from the BBC Website:

I don't think stockpiling four months of food and water is necessary - I think that would be overreacting. But what you can do is have a strategy and be aware of how the virus spreads. So in the event of a pandemic, it might for example make sense not to go to work during rush hour to avoid crowded tube trains. Or if a friend calls and says he's feeling ill, it might not be the best idea to pop round to see him straight away, and so on.

On any one day, about five per cent of the community will be ill, so 95% of the population will still be perfectly capable of going about their daily business. In fact, one of my biggest concerns is the worried well - people who will lock themselves away during a pandemic. That could amount to a huge number. And if that happens, and everybody goes into panic mode, the economy will collapse.

John Oxford, Professor of Virology at the University of London

 We get so wrapped around the axle of how many people will be sick -- we all use the figures 30% and 40% interchangeably -- that it is important to remember that all 30% will not be sick all at the same time.  Those figures are aggregates.  So Professor Oxford's belief that on any given day during a pandemic only 5% of the population is actually too ill to report to work is significant.  As Oxford notes, the "worried well" are the ones we must convince to come to work, unless they are tending to ill loved ones or watching small children.  Also interesting is his statement that he continues to keep the M2 inhibitor Amantadine in his icebox.  Amantadine is an antiviral designed to stop the influenza A's M2 lipid coat from dissolving as it enters a cell.  Unfortunately, virtually all Influenza As -- including H5N1 -- are Amantadine-resistant.  But he figures it's worth a try anyway.

What separates this BBC documentary/drama from others, such as the excellent National Geographic piece from 2005 and the 2006 ABC TV movie "Fatal Contact - Bird Flu in America," are the videos.  I had never seen still photos or video of the dying/dead tigers at the Bangkok Zoo in 2006, nor had I ever seen the actual die-off at China's Qinghai Lake in April-May 2005, nor had I ever seen actual newsreel footage of post-Spanish Flu sufferers of encephalitis lethargica. The photos and videos are outstanding.  Also chilling are the words from Los Alamos National Laboratory scientist and forecaster Dr. Catherine Macken.  Dr. Macken's words should be taken very seriously.  She recounts how, in the aftermath of 9/11, the US government charged Los Alamos to come up with the most plausible bioattack upon Americans. Homeland Security was expecting anthrax, or maybe smallpox, or some other pathogen.  Instead, LANL told Homeland the most likely scenario was an H5N1 pandemic. 

If you only have one opportunity to get someone to watch a documentary about H5N1, this BBC documentary is the one to watch.  It is absolutely superb. You can also download it to Sony PSP or iPOD video.

Ebola confirmed in Congo outbreak

Posted on Wednesday, September 12, 2007 at 10:42AM by Registered CommenterScott McPherson in | CommentsPost a Comment

ebola%20poster%20congo.jpgThe WHO has confirmed the dreaded Ebola as the cause of the deaths of scores of villagers.  Some 166 deaths may or may not be linked to Ebola, but the confirmation of at least five deaths as being caused by the hemorrhagic fever caues one to reasonably conclude that many other deaths will be attributed to the disease.  Ebola has a 90% Case Fatality Rate (CFR).

The following story is from Brietbart.com as reported by wire service AFP:

The World Health Organisation (WHO) has confirmed a major outbreak of the deadly Ebola virus in the Democratic Republic of Congo, and said 166 deaths there since April could be linked to the disease.

The outbreak of the highly-contagious Ebola haemorrhagic fever, in the Western Kasai province, was confirmed by specialist laboratories in the US and Gabon, the WHO said in a statement on its website.

The tests have also confirmed the presence of Shigella dysentery type 1, another but less deadly disease.

"As of 11 September 2007, WHO is aware of 372 cases and 166 deaths associated with the ongoing event in the province. Additional samples have been taken for further laboratory analysis," the WHO said in a statement.

Speaking to journalists in Geneva Tuesday, a WHO spokesman stressed that another illness other than Ebola could yet be responsible for some of the deaths, possibly the Shigella infectious disease. Of five samples sent to one laboratory, all showed signs of Ebola.

Ebola causes the patient to bleed under the skin and in severe cases, from the mouth, ears and eyes. The virus, which has no known cure, is highly infectious for those who come into contact with a victim's body fluids.

Ebola had previously killed some 450 people in the DRC since 1976, and 1,200 people across the whole of Africa in the same period.
