Robert Webster (virologist) - H5N1 Work

H5N1 Work

Webster's work with the avian flu can be said to have sprung from a beach walk with fellow researcher Graeme Laver, on which the men noticed a large number of birds dead along the shoreline. Webster wondered whether it was possible that the birds had died from the avian flu, and subsequently traveled to an island to take samples from hundreds of birds. This led to more trips, and eventually Webster discovered a link between the avian flu and the human flu. This link meant one thing to Webster: that it is possible for the avian and human viruses to combine, creating a new virus that humans would have no antibodies to. In an interview with NBC, he said that when he first reestablished there was a link, few paid attention to what he saw as a great danger. He was quoted as recalling that "The veterinarians said, 'Not a problem.' The medical people said, 'Not a problem.'" However, Webster theorizes that the only event that has to occur to begin a flu pandemic is the mixing of avian and human flu strains in the same mammalian cell - most likely in a pig. Pigs are similar enough in genetic makeup to humans that they are susceptible to the human flu; also, in many areas, pigs come in close contact with chickens or ducks, making it likely that they will catch the avian flu.

Another danger that Webster has uncovered is the duck. Ducks, while capable of catching and transmitting the avian flu virus through contact with chickens, seldom sicken and die from the exposure. Being alive and quite healthy, the ducks are then capable of spreading the virus to other areas.

He "is a world-renowned virologist, an expert in the structure and function of influenza virus proteins and the development of new vaccines and antivirals. He has spent more than 50 years studying influenza, and was the first to isolate and identify Asian lineage HPAI A(H5N1)."
