flu strains
Influenza genetic variations
Flu strains are distinct genetic variants of the influenza virus.
The flu mutates rapidly, producing new strains that may evade immunity from previous infections or vaccines: This year's vaccine targets three different flu strains.
Strain names like H1N1 or H3N2 identify surface proteins that determine how the virus spreads and how severe infection may be.
