Influenza A Virus

Influenza A Virus (subtype H3N2)

Jan 13th – The Flu season is upon us! Influenza A virus subtype H3N2 (A/H3N2) is a subtype of viruses that causes influenza. 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. Fortunately, if you got your flu shot this year, this is the dominant stain that is present in the quatravalent vaccine. #365DaysOfMicroscopy
