Scientists believe the increase may be a result of more frequent contact between humans and wild animals, as well as the growing trade in wild animals, both legal and illegal.


Towards the end of the 1990s, several Asian countries lived one of their worst health nightmares. A new, highly pathogenic, strain of Avian Influenza known as H5N1 killed hundreds of people. Over the next years, more than 9-million chickens were destroyed in an effort to stem the epidemic. Scientists believe the H5N1 virus was transmitted from wild birds to domestic poultry and pigs, which then passed it to humans. H5N1 is just the latest of various influenza strains that have killed up to 100 million people over the last century.

Now scientists are concerned about the appearance of new illnesses. Jonathan Sleeman is the director of the National Wildlife Health Center at the U.S. Geological Survey.
