Health officials have long been worried that the next deadly global epidemic--a slate wiper, as epidemiologists call it--would be a new kind of deadly flu to which humans have no resistance. And since the 1960s, their fears have been focused on the H5N1 virus, a bird pathogen that is generally harmless in its host species (ducks and other wildfowl) but extremely deadly when contracted by chickens. It was H5N1 that struck Hong Kong in 1997, where it went straight from chickens to humans. Authorities quickly killed 1.4 million birds, and although six people died, the disease never managed...
...Parasites are a very powerful evolutionary source, affecting everything from a bird’s genetic makeup to plumage, to the way it behaves, so we are trying to understand what happens when a bird meets a new pathogen,” Edwards said...
Recently-acquired knowledge of the entire genetic sequences of many deadly pathogens will aid tremendously in the research, he said. Scientists hope to duplicate proteins created by pathogens in order to survive, and then create drugs to inhibit those particular proteins, destroying the pathogen, Kasper said...
...across a hallway to create an isolation ward where one patient already lies feverish. Asked if his facility can cope with SARS, Dr. Li shakes his head. "All we have is our hands," he says. Even those go without basic protection against the virus that causes SARS. As the pathogen migrated from big cities to provinces like Hebei, the government sent Li boxes of latex gloves?all right-handed. He forces one onto his left hand and asks, "How am I supposed to work like this...
