Flu Viruses Take One-Way Ticket out of Asia, Then Travel the World

Seasonal influenza strains constantly evolve in overlapping epidemics in Asia and sweep the rest of the world each year, according to an international research team publishing in the 18 April issue of the journal Science. The findings suggest that by focusing surveillance efforts on East and Southeast Asia, researchers may be able to extend their forecast of the flu strains most likely to cause epidemics, which may in turn help experts decide which strains should go in the flu vaccine each year.
