with multiple waves of flu infections and both H1N1 and H3N2 strains circulating at the same time. The virus normally only sees one peak per season and has a strong predominance of one strain over ...

Levels of the virus remained high for the first seven days after the cheese was made and then dropped a bit in the cheeses produced at pH levels 6.6 and 5.8. But importantly, the virus remained ...

Most flu cases appear to be from influenza A strains, with a split between influenza A/H3N2 and influenza A/H1N1. These are two different subtypes of the influenza A virus. Researchers believe ...
