Entries in H5N1 (11)

While world focused on swine flu, bird flu just kept on trucking in 2009

I just got a news story in my Google Alerts folder.  Opening it and clicking on the accompanying link, I was shown something I had not seen in ages and ages -- namely, the WHO statistics for H5N1 bird flu for 2009.

Now, you know how fond I am of saying that influenza plays "King of the Mountain."  That image of children trying to topple the reigning King at the top of the dirt pile (growing up in southern Florida, with all its construction and fill dirt, that game was enormously popular) is exactly what I try to convey with regards to flu strains.

Pandemic viruses play that game quite well.  In fact, I have not bothered to even get my seasonal flu shot yet, because I believed that there would be no seasonal flu until very late in the season.  based on the stats I have been getting from various flu sources, I was right on the money.

So there is virtually no seasonal flu, anywhere in the world, save for some Influenza B that I recently read was either in China or Japan.

But there is one flu strain that keeps on trucking, unabated by events that combine to make seasonal flu virtually nonexistent.  And that is H5N1 bird flu.

It can be argued, possibly successfully, that H5N1 isn't seen in people enough for swine flu to even care about it.  H1N1v just casts a look over its shoulder at H5N1 and ignores it.

But I was really, really surprised to find that 2009 was a pretty good year, or a pretty bad year, depending on whether you are a researcher or the virus itself.  Globally, there were 72 cases of H5N1 in humans, with 32 deaths.  That is still a 44.4% case fatality rate, or CFR. The two extremes for CFR were Egypt, with 39 reported human cases and 4 deaths, for a 10% CFR; and Indonesia, with 20 reported cases and 19 deaths, a whopping 95% CFR.  Of course Indonesia has just gotten over years of governmental madness courtesy of their former health minister.  This somewhat refreshing reporting of cases may skew the CFR heavier, as certainly more human bird flu cases must have been encountered and just not reported.  Or reported and covered up.  Who knows?

In fact, the year 2009 shaped up as the fourth-worst year for human H5N1 cases on record, surpassed by (in order) 2006, 2005 and 2007 in terms of the sheer number of confirmed human cases. From 2008 to 2009, confirmed reported human bird flu cases jumped by 63% while deaths stabilized.

In 2010, we already are reading about more accounts of bird flu in poultry, in all the usual spots.  This recent news, when combined with the 2009 data, should make us all more concerned than ever that a hybrid virus is more than just hypothetically possible.  A glance at the WHO chart also shows us that the areas of the world where human H5N1 cases proliferate are also areas where the H1N1v virus is just beginning to make its inroads. China has recently announced it expects a constant flow of H1N1v human cases throughout 2010.  China had 7 reported human bird flu cases in 2009, its third-highest year on record and the highest number since 2006.

Indeed, in those areas where H5N1 is assumed to be endemic, human cases are on par with previous years.  For example, Egypt's 2009 human bird flu total (39) was 500% higher than 2008's (8).  Vietnam's 5 cases was not statistically different than the previous two years.  And in each and every one of those nations, H1N1v insinuates itself further and deeper rural villages and farms. 

In the midst of all this, we read news reports accusing the WHO of generating a "fake pandemic".  What are these people ingesting?   A key indicator of a pandemic (you know, other than a genetically novel virus)  is a rising of pediatric mortality.  Pediatric mortality in 2009 was three or five times the running average for a normal flu season, according to different sources.  Our own CDC now says upwards of 11,000 Americans died of swine H1.  The overwhelming majority of them were under age 55.  And this virus is far from finished. 

To its credit, the WHO fired back to the flat-Earthers who claimed that the raising of the pandemic level to Phase Six was inspired by the drug companies, and some even claim this virus was genetically engineered.  These are the same drug companies who do not make a lot of money from vaccines.  To even insinuate that drug companies make huge sums of money from vaccines is to show a colossal lack of understanding about how drug companies make their fortunes.  Vaccines represent a huge downside financial risk to their bottom lines, precisely for the reasons we are seeing and reading about today.  Stories abound regarding this nation and that nation trying to renegotiate its vaccine buying agreements in an effort to reduce its purchases.  It is a wonder that drug companies even make vaccines anymore.

But that is a rant best saved for another time.  I wanted to close this blog by saying that we need to watch Asia and Egypt like a hawk.  Because H5N1 had a very good year on the books in 2009.  It continues to be productive and it has not read the memo that it is supposed to roll over and play dead while swine flu takes center stage.
