H3N2 News and Research

RSS

Influenza A virus subtype H3N2 (also H3N2) is a subtype of viruses that cause influenza (flu). H3N2 viruses can infect birds and mammals. In birds, humans, and pigs, the virus has mutated into many strains. H3N2 is increasingly abundant in seasonal influenza, which kills an estimated 36,000 people in the United States each year.

Flu cases continue to rise throughout the U.S.

The rate of influenza cases throughout the U.S. continues to rise.
