Tracking Bird Flu Cases

Bird flu deserves its own thread for tracking suspected and confirmed cases. It's not the pandemic virus, but it is still an ongoing and significant threat because of its virulence. As Margaret Chan, the Director General of the WHO says, we do not know how H5N1 will react under pressure from the pandemic virus, H1N1. All of the countries with endemic H5N1 are also reporting cases of swine flu. As everyone should know by now, the new concern revolves around what will happen if the two viruses co-infect the same host. Flu viruses exchange genetic material with each other all of the time. Right now we have a pandemic virus that is very transmissible, but does not kill the majority of people infected. Bird flu, on the other hand has a case fatality ratio (CFR) of around 60%.

In the past year, something different began to happen in Egypt. We started seeing many cases of young toddlers infected with mild cases of bird flu there. But, we also saw some older children and adults that had fatal cases. No one has yet explained why the disease began to change in Egypt. Just prior to the beginning of the swine flu cases appearing in the US and Mexico, the WHO was going to send in a team to Egypt to investigate why this was so. And, then the swine flu pandemic began in earnest, leaving this question unanswered. Why this situation has changed in Egypt but not in Indonesia, is most likely very important information.

Egypt continues to try to isolate swine flu cases. At some point, they won't be able to contain that virus, and will have to bow to the inevitable. Nobody knows what will happen then, but the Egyptians are clearly concerned. Remember, this is the country that slaughtered its entire pig population a few months ago to international dismay. Maybe they were right to do so, as we are now finding swine flu in pigs in Canada, Argentina and Australia. Pigs, the perfect mixing vessels for influenzas, may have been harboring the current swine flu for years undetected because they are almost never tested in most countries unless they are sick. This lack of disease surveillance is now being compensated for by a heightened awareness and increased testing of pig herds in many countries.

With all of that being said, here is a translation regarding a new case of bird flu, H5N1 in another child in Egypt. They do not state the child's age in this article, and some translations are saying that this is a male child. They would have isolated her anyway with bird flu, but with swine flu also in Egypt, they are likely to be very worried. Descriptions of these cases almost always mention dead birds being found in the same location. That of course, is going to be helpful in determing which flu they are dealing with at least for now, but maybe not later...

H5N1 Infected Chicken Carcass On Hong Kong Beach

Situated at the mouth of the Pearl River Delta, which serves as a catchment area for dozens of tributaries flowing out of the highly industrialized and economically booming Guangdong Province, the northern shore of Lantau Island is on the receiving end of one of the more heavily polluted waterways in the world.

Almost two years ago (February, 2009) we saw numerous reports of dozens of dead birds - mostly poultry - washing up on the beaches of Lantau Island that subsequently tested positive for the H5N1 virus.

Despite Chinese denials, this sparked great suspicion in Hong Kong (never proven) that bird flu infected poultry were being disposed of somewhere in Guangdong Province by farmers dumping their carcasses into the river.

Given its location (northern shore of Lantau island), its level of decomposition (advanced), and the lack of poultry operations within 3 kilometers of the find, the notion that this bird may have flowed down the Pearl River is not without merit.

S. Korea Confirms H5N1 On Two Poultry Farms

In a story we've been following for several days, last night officials announced that two poultry farms located in different parts of South Korea have tested positive for the highly pathogenic H5N1 bird flu virus.

Culling is reportedly complete at a duck farm in Cheonan and a poultry farm in Iksan City. Both farms remain under quarantine, and movements of vehicles and people are restricted.

During their last H5N1 outbreak in April-May 2008, South Korea waged a month-long, very expensive battle to contain the virus that resulted in the culling of more than 8 million birds.

A Summary of Human H5N1 Cases in 2010

FluTrackers - View Single Post - A Summary of Human H5N1 Cases in 2010

Laidback Al always does great charts, summaries, and analysis.

In 2010, while the pH1N1 virus continued to infect people and be the focus of influenza news stories, human H5N1 infections continued to be identified in several countries. As discussed below, the virulence based on confirmed case has not declined and the potential for an H5N1 pandemic has not diminished.

Background

H5N1 avian influenza ("Bird Flu") is an internationally reportable disease. Since 2003 until December 29, 2010, the World Health Organization (WHO) has reported a total of 512 confirmed human cases of H5N1 (link). The 18 cases associated with the initial human outbreak of H5N1 in Hong Kong in 1997 are not included in the official WHO totals (link). WHO provides a current time line of significant events associated with the H5N1 virus (link).

Japan's Bird Flu Dilemna

Japans Bird Flu Dilemma

My guess is that they will cull these birds though they cannot destroy all of this species. They cannot let the sick infect the others. Now if this was Korea, probably all would be exterminated...

Over the past several weeks a small number of relatively rare, threatened, and legally protected Hooded Cranes have turned up carrying the H5N1 virus at the national wildlife reserve in Izumi City, Kagoshima Prefecture (see Japan: 5 Hooded Cranes Test Positive For H5N1).

Of the roughly 10,000 Hooded Cranes in the world, roughly 80% are believed to over-winter in Izumi City.

...when the birds in question are a legally protected species, about all wildlife authorities can do is to try to separate sick or enfeebled birds from the rest of the population . . . . and hope the infection dies out.

Fukushima, Japan

http://mdn.mainichi.jp/mdnnews/news/20110120p2a00m0na017000c.html

Highly pathogenic H5N1 bird flu has been detected in the corpses of two migratory wild ducks found at a reservoir here, prefectural authorities announced on Jan. 19.

From Jan. 4 to Jan. 10, the prefecture gathered seven bird corpses from the reservoir and sent them for testing at the National Institute for Environmental Studies in Tsukuba, Ibaraki Prefecture. Four of the corpses tested positive for Type-A influenza, and further investigation at Hokkaido University in Sapporo found that two had the highly pathogenic H5N1 bird flu. The other two are still being investigated.

The prefecture set up a response center on Jan. 19 and on the morning of Jan. 20 began sending inspectors clad in protective suits to 59 poultry farms in a 10-kilometer radius area under supervision that includes neighboring towns. The inspectors are interviewing farmers, looking for signs of contagion such as changes in the death or egg-laying rates of chickens, and checking that farms have anti-contagion measures in place such as nets to keep out wild birds and supplies of disinfectant on hand.
