A bird flu resource guide
World health experts have been alarmed by this new, deadly strain of bird flu since it killed more than 30 people in Thailand and Vietnam last year. And television outlets ranging from PBS to local television stations have weighed in on the chances of a bird flu outbreak in the United States.
On Tuesday, President Bush called on Congress to spend $7.1 billion on preparedness for a pandemic, which could be brought on by a mutated strain of bird flu (technically, the H5N1 virus). Experts have warned that in such an event millions of people worldwide could be killed.
To health experts, the proposal seemed long overdue. To the public, it was a double-edged sword, offering a sense of relief that the government was acting to protect the country, but also stoking fears that a superflu is on its way.
Nevertheless, no one really knows if the latter is really true.
"In terms of the bird flu, which is currently devastating the bird population and has made 150 people sick (worldwide), half of which have died, nobody knows if that would ever cause a human pandemic, or if so, when," said Arthur Reingold, professor of epidemiology at the School of Public Health at the University of California at Berkeley.
"But it's possible," Reingold said. "That's what has people nervous, appropriately."
Nonetheless, there are good resources on the Internet where people can get factual, lucid information about the bird flu, its danger and its spread. Here are a few of them.
The Centers for Disease Control and Prevention hosts Web pages devoted to the subject, offering facts about previous flu pandemics and bird flu.
The federal government recently set up an
The World Health Organization offers regular updates on what's happening globally with the spread of avian flu.
The National Institute of Allergy and Infections Diseases has a newly expanded Web site called Focus on the Flu. The site has 30 reports on research in the field.
Certainly, there's good cause for concern, if history is a guide.
There have been three flu pandemics in the last century, the largest being in 1918, when between 25 percent and 35 percent of the world's population was affected. Known as the "Spanish flu," the virus killed more than 500,000 people in the United States, and about 50 million people worldwide.
Scientists are currently researching genetic mutations of the Spanish flu virus to understand what caused it and to compare it with the H5N1 virus.
Health experts have cautioned that regardless of whether it involves an avian flu or another strain of virus, another human pandemic is as inevitable as devastating earthquakes in California and hurricanes on the Florida coast.
"What are the chances that some kind of pandemic flu will devastate world populations again? It's almost certain," Reingold said.
Avian flu is a contagious disease caused by viruses that normally infect birds and, occasionally, pigs, according to the World Health Organization. The avian flu has also, rarely, crossed the species barrier to infect humans.
