I am going to start keeping up with this new flu virus and posting relevant articles. I realize that this has nothing to do with Time Travel but since this virus could mutate into a form where it could be transmitted from humans to other humans and kill potentially millions among millions, I felt as if opening up a thread was the right thing to do. I will look out every day for new articles concerning the Avian Flu.
Background on the Avian Flu - H5N1 Virus
Avian influenza (also known as bird flu) is a type of influenza virulent in birds. It was first identified in Italy in the early 1900s and is now known to exist worldwide.
Infection
The causative agent is the avian influenza (AI) virus. AI viruses all belong to the influenza virus A genus of the Orthomyxoviridae family and are negative-stranded, segmented RNA viruses.
Avian influenza spreads in the air and in manure. Wild fowl often act as resistant carriers, spreading it to more susceptible domestic stocks. It can also be transmitted by contaminated feed, water, equipment and clothing; however, there is no evidence that the virus can survive in well cooked meat.
The incubation period is 3 to 5 days. Symptoms in animals vary, but virulent strains can cause death within a few days
Avian Influenza in Humans
While avian influenza spreads rapidly among birds, it does not infect humans easily, and there is no confirmed evidence of human-to-human transmission. Of the 15 subtypes known, only subtypes H5 and H7 are known to be capable of crossing the species barrier.
The symptoms of avian influenza in humans are akin to those of human influenza, ie. fever, sore throat, cough and in severe cases pneumonia. Human deaths from avian influenza were unknown until 1997, when six people in Hong Kong died from the particularly virulent H5N1 strain.
In January 2004, a major new outbreak of H5N1 avian influenza surfaced again in Vietnam and Thailand's poultry industry, and within weeks spread to ten countries and regions in Asia, including Indonesia, South Korea, Japan and China. Intensive efforts were undertaken to slaughter chickens, ducks and geese (over 40 million chickens alone were slaughtered in high-infection areas), and the outbreak was contained by March, but the total human death toll in Vietnam and Thailand was 23 people.
It is feared that if the avian influenza virus undergoes antigenic shift with a human influenza virus, the new subtype created could be both highly contagious and highly lethal in humans. Such a subtype could cause a global influenza pandemic, similar to the Spanish Flu that killed over 20 million people in 1918. In February 2004, avian influenza virus was detected in pigs in Vietnam, increasing fears of the emergence of new variant strains.
Fresh outbreaks in poultry were confirmed in Ayutthaya and Pathumthani provinces of Thailand, and Chaohu city in Anhui, China, in July 2004.
In North America, the presence of avian influenza was confirmed at several poultry farms in British Columbia in February 2004. As of April 2004, 18 farms have been quarantined to halt the spread of the virus. Two cases of humans with avian influenza have been confirmed in that region.
In August 2004 Avian Flu was confirmed in Kampung Pasir, Kelantan, Malaysia. Two chickens were confirmed to be carrying H5N1. As a result Singapore has imposed a ban on the importation of chickens and poultry products. Similarly the EU has slapped a ban on Malaysian poultry products. A cull of all poultry has been ordered by the government within a 10KM radius of the location of this outbreak
Prevention and Treatment
Avian influenza in humans can be detected reliably with standard influenza tests. Antiviral drugs are clinically effective in both preventing and treating the disease. Vaccines, however, take at least four months to produce and must be prepared for each subtype.
Increasing Virulence
In July 2004 researchers, headed by H. Deng of the Harbin Veterinary Research Institute, Harbin, China and Professor Robert Webster of the St Jude Children's Research Hospital, Memphis, Tennessee, reported results of experiments in which mice had been exposed to 21 isolates of confirmed H5N1 strains obtained from ducks in China between 1999 and 2002. They found "a clear temporal pattern of progressively increasing pathogenicity".

Jan. 23 (Bloomberg) -- Bird flu has killed two more people, bringing the total number of deaths since the virus emerged in humans to at least 82, the World Health Organization said today on its Web site.
The deadly H5N1 virus that causes avian influenza has infected 151 people since 2003, when the first bird-to-human transmission occurred in eastern Asia, the WHO said. The most recently confirmed deaths occurred in Indonesia, the group said.
Bird flu has spread from Southeast Asia to the fringe of Europe in recent weeks, heightening concerns that it may mutate into a form that can be passed from one person to the other. Such a virus may touch off a flu pandemic similar to the one that killed as many as 50 million people in 1918.
The U.S., the European Union, Japan and others last week pledged $1.9 billion to fight the H5N1 virus that causes bird flu and prevent a pandemic should the virus adapt to humans. About 140 million fowl worldwide have died or been culled to stem outbreaks, causing more than $10 billion of economic losses.
In Turkey, the government has confirmed 21 human infections and almost 1 million fowl have died or been killed to stem outbreaks. Analysis of viral material from one patient in Turkey showed genetic mutations where the virus binds to human cells, the WHO said last week. The genetic change indicates the virus may bind more readily to human cells than to avian cells.
China's health ministry reported the nation's 10th case of bird flu infection, the official Xinhua News Agency reported today. A 29-year-old woman from Jinhua Town of Chengdu City, in China's Sichuan Province, has avian influenza, Xinhua said, citing the health ministry. The woman is hospitalized in critical condition, the news agency reported.

If any of you object to this then I am sorry, I just wanted to keep everyone updated on the current flu.
Also, if there are any articles that you wish to show or if there are any comments, feel free to write anything you wish.
