A new study uncovers how Oropouche virus is breaking out of the Amazon, spreading across Brazil and beyond. Scientists warn that environmental changes, human mobility, and viral evolution are driving ...
The exchange of genetic material between two closely related strains of the influenza A virus may have caused the 1947 and 1951 human flu epidemics, according to biologists. The findings could help ...
Scientists worry the species could generate a hybrid virus better able to spread to and among people

The latest bird flu outbreak in South Korea is presumed to be a new type of avian influenza strain that is a reassortment of highly pathogenic strains that spread in Europe last year, the quarantine ...
Emory scientists have been probing the RNA packaging factors that limit reassortment between avian H7N9/H5N8 strains and a well-known strain (H3N2) that has been dominating the last few human flu ...
The completion of the genetic sequencing of the 1918 influenza A virus by Taubenberger et al. 1 and the subsequent recovery of the virus by Tumpey et al. 2 using reverse genetic techniques are ...
