H5N1, Bird Flu Updates - page 2
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... Read More
Suphan Buri, Thailand
One thousand dead ducks is not a good sign. This is a bad time of year.
Of course, the Thai also have to deal with swine flu in their country as well so everyone is concerned that a co-infection in human hosts with the H5N1 virus not occur, hence the targeted education campaign on bird flu for the local population.
Quote from enews.mcot.net(hat tip crofsblog)About one thousand ducks were found dead of unknown causes in Suan Taeng sub-district of the Suphan Buri provincial seat on Friday. Government veterinary workers destroyed the rest of the ducks in the flock to prevent a possible outbreak of influenza and are now awaiting for laboratory test results from Kasetsart University.
Director-General Dr Manit Theeratantikanont of the Disease Control Department said that according to the reports from doctors and expert observers following the bird flu situation, the lower northern and central provinces must be more closely monitored as bird flu patients were previously found in Sukhothai, Kamphaeng Phet, Phichit, Phitsanulok, Phetchabun, Uthai Thani, Kanchanaburi and Suphan Buri.
Dr Manit urged local residents to help keep close watch on the situation and inform concerned officials or health volunteers if any wildfowl or domestic fowl is found dead from unknown reason. (TNA)
h5n1 hazards for survivors
there has been much speculation all along that this was a possibility. here is a study in mice looking more closely at this phenomenon. considering the mortality rate for bird flu though, especially in indonesia (over 80%), this might be a relatively rare occurence.
as crofs wonders, whether or not this can occur from other types of infliuenza is indeed, a very good question.
Quote from crofsblogs.typepad.comevidently h5n1, like the spanish flu, may cause longterm harm in its survivors: highly pathogenic h5n1 influenza virus can enter the central nervous system and induce neuroinflammation and neurodegeneration. the abstract:
one of the greatest influenza pandemic threats at this time is posed by the highly pathogenic h5n1 avian influenza viruses. to date, 61% of the 433 known human cases of h5n1 infection have proved fatal.
animals infected by h5n1 viruses have demonstrated acute neurological signs ranging from mild encephalitis to motor disturbances to coma. however, no studies have examined the longer-term neurologic consequences of h5n1 infection among surviving hosts.
Alan Sipress: Playing chicken with a nightmare flu
This is why we continue to watch and worrry about bird flu. Lots of really great info
from this author on the political/economic history involved with bird flu. Information
on contagious diseases tends to be heavily censored in many countries for economic reasons. Everyone knows this, right? Well, it is true. Certainly, everytime an outbreak
of what is always described as a low pathogenic avian virus in North America occurs,
all information is at least somewhat censored here and in Canada as well. The public
is always assured that there is no danger, and most of the time that is probably true.
The USDA has two roles. One is to protect the public but the other is to promote US agricultural products including poultry and livestock. Sometimes, one role takes precedence over the other, and perhaps they are not as transparent about this as we might like. This is no different from countries like Indonesia where bird flu is endemic, and bird flu certainly has been known to occur on the beautiful tourist paradise island of Bali, a source of tourist dollars that would be at risk if Australians were to suddenly hear of an increase in outbreaks of the virus. For two years now, Indonesia has kept silent about those outbreaks.

From the Washington Post today, an outlook & Opinion column by Alan Sipress, WaPo’s economics editor and the author of the book "The Fatal Strain: On the Trail of Avian Flu and the Coming Pandemic."
Sipress has spent years on the trail of avian flu, traveling across much of Asia as he filed reports. He gives us some deep background into the concerns held by many scientists that the H5N1 avian flu virus could meet up with, and swap genetic material, with the pandemic H1N1 virus.
The result could be a new, highly virulent, and easily transmissible pandemic virus.
Nov 18, '09 by indigo girlEgypt: 88th H5N1 Infection Reported
Quote from afludiary.blogspot.comWhile we've seen a steady stream of reports of infected poultry coming out of Egypt over the past few months, this is the first confirmed human infection since late September.
Date of report: 17 November 2009
District: Sedy Baher
Event summary: Man, 21 years old, university student. The patient began to experience fever, cough and difficulty breathing November 11. He was admitted to Maamoura Chest Hospital on November 15 and received Tamiflu. He reported having slaughtered and other close contact with sick poultry. He was reported in stable condition November 17. The MOH reported this was the 88th case of highly pathogenic avian influenza in Egypt.
Nov 18, '09 by indigo girlBeni Suef, Egypt
Quote from www.saidr.org
Date of result: 8 November 2009
Governorate: Beni Suef
Village: El Awawna
Type of rearing: Household
Species: Mixed (Chickens, ducks, turkeys)
Number of birds: Not reported
Vaccination status: Chickens vaccinated
Purpose of sampling: PDS
The mortality started in a turkey provided as a gift from another family in the same village. The turkey died, and a duck developed nervous manifestations.
The layer chickens were vaccinated, were apparently healthy at the date of sampling, and were still alive with neither illness nor mortality for 3 successive days after sampling until the day of culling.
The poultry (pigeons and turkeys) at the household which provided the turkey as a gift had no problems and tested negative by PCR for HPAI.
The team concluded that the vaccinated chickens were previously infected and shedding the HPAI virus, infecting the ducks and newly introduced turkey. This reflects the risk of silent spread of HPAI unless there is an efficient surveillance program to monitor the virus circulation in vaccinated flocks.
Nov 20, '09 by indigo girlH5N1 reminds us it's still here, despite swine flu pandemic
Scott McPherson is the Chief Information Officer [CIO] of the Florida House
of Representatives, and was an invited speaker at the recent CIDRAP
Conference on "Keeping the World Working during the Pandemic" held in
Minneapolis. I had the distinct pleasure of "hanging out" with Scott at most
of the presentations there as well as with my good friend, Mike Coston, author
of the Avian Flu Diary blog as both had been invited as speakers by Dr. Osterholm
as representatives of the "new media" aka bloggers. I was just a tag along
flu buddy but happy to be invited.
Quote from www.scottmcpherson.netMore at:What is interesting is the case of the Egyptian college student. He reportedly had slaughtered poultry just days before his onset of symptoms, and it is to the Egyptian doctors' credit that they had the presence of mind to test the lad for H5N1 as well as H1N1.
There is no word if a co-infection was present, but this does confirm the concern that Egyptian authorities have expressed ever since they ordered the slaughter of every pig in the nation (overkill, to be sure). Namely, they were worried about Egypt becoming the mixing vessel for an H1/H5 mutant virus.
This makes the third time and third locale that H5 and H1 have rubbed elbows. In Vietnam and in Indonesia, the two viruses were in extremely close physical proximity to one another. Now, in the midst of the current (first?) wave of swine flu in Egypt, a young adult acquired bird flu.

Nov 20, '09 by indigo girlKawaoka, UW-Madison receive $9.5 million from Bill Gates for flu research
Quote from www.scottmcpherson.netMore at: http://www.scottmcpherson.net/journa...es-for-fl.htmlThe international team of scientists working on the project will look for mutations in viral proteins that allow avian influenza, commonly called bird flu, to bind to human receptors.
Avian viruses, the release said, don't generally infect humans, but a mutation happens every now and then that could allow the virus to adapt to human cells.
By identifying mutations that might allow this to happen, the project team hopes an early warning system could be developed to make it easier to predict pandemic potential of influenza viruses.
Nov 24, '09 by indigo girlBird Flu Endemic in Three More Countries
Quote from www.manilatimes.net(hat tip flutrackers/treyfish)
Since 2003, outbreaks have been reported in poultry flocks in 60 countries in Asia, Europe and North
Africa. The virus is now considered endemic in Egypt, Indonesia and Vietnam.
"First, it places those in direct contact with birds--usually rural folk and farm workers--at risk of catching the often-fatal disease. Second, the virus could undergo a process of 'reassortment' with another influenza virus and produce a completely new strain," the WHO said in a statement.
Health experts do not count out the possibility that the bird flu virus may combine with the A(H1N1) virus, producing a deadlier and more contagious disease.
Nov 25, '09 by indigo girlChina: Zhong Nanshan On Viral Reassortment
We owe a hugh debt to this man, Dr. Zhong. He is the guy who pressured the Chinese govt into closing down the "wild flavor" restaurants where the animal reservoirs of the SARS virus were being slaughtered and served. The practice of eating many different types of wild animals was a popular symbol of the increasing affluence of prosperous Chinese.
As everyone knows, the govt of China denied the existence of this disease for several months, allowing the virus to be unleashed on the populations of other countries as well.
Dr. Zhong is speaking out publicly again, this time about the cover up of the true number of cases of H1N1 in his country, and also of the danger of a possible co-infection of human hosts with H5N1 bird flu and H1N1 together.
Quote from afludiary.blogspot.comLast week Zhong publicly questioned the official death toll from the H1N1 virus (see Zhong Nanshan On China's Death Toll), which brought a response 24 hours later from the Health Ministry, promising to punish anyone caught hiding fatalities.
Today, Reuters has a long and very informative article regarding his concerns over the possible reassortment of the pandemic H1N1 virus with H5N1 bird flu.
Reassortment occurs when two compatible viruses infect the same host (human, pig, bird, etc.) at the same time, and swap genetic material. This can produce a hybrid virus, with parts of both viral donors.
Nov 28, '09 by indigo girlEgypt: WHO Update On 89th H5N1 Infection
Quote from afludiary.blogspot.comAlthough FluTrackers had word of an 89th confirmed human H5N1 infection out of Egypt a couple of days ago, the WHO has posted an official update today, along with a new table of cases by country.
It should be noted that Indonesia stopped reporting H5N1 cases nearly a year ago, after a couple of years of less than stellar reporting.
Numbers from other countries, where surveillance and reporting may be less than optimal, probably don't reflect the true picture either.
Dec 1, '09 by indigo girlVietnam
According to the translators over at flutrackers, this man had eaten duck soup about 7 days prior to being admitted. The soup is made of raw duck's blood. These ducks can harbor bird flu without showing any s/s of it.
Unfortunately, this is the time of year when we can expect to see more cases of H5N1. Occurring in the same region as the more transmissible swine flu, it is worrisome. Bird flu is endemic in Vietnam.
Quote from crofsblogs.typepad.comUPDATEVia Reuters: PRESS DIGEST - Vietnam newspapers - Dec 1. Excerpt:
The Health Ministry confirmed the H5N1 virus has killed a 23-year-old man last month in the northern province of Dien Bien, the fifth fatality in Vietnam so far this year. Vietnam currently has no outbreaks among poultry, the Agriculture Ministry said.
This link is saying it was duck blood pudding not soup. At any rate, the
exposure to duck blood, is problematic. I wonder, did he slaughter the
bird himself? Very risky with no PPE, and then to eat it raw...

No, bird flu has not disappeared except in our US news reports. It is still
very much an issue.
Quote from afludiary.blogspot.comFor an update go to: http://afludiary.blogspot.com/2009/1...and-egypt.htmlWith the first day of winter less than a week away in the northern hemisphere, and cooler weather already present in many places, we are beginning to see an upsurge in reports of B2B (bird to bird) H5N1 avian flu around the world.
While hardly earth shattering news (we see this pattern every year), it is an important reminder that there are other flu viruses out there that deserve our attention.
