Can You Get the Flu Twice in One Season?

If you have had the flu this season, are you 100% safe for the rest of the season?

Experts say no. Because multiple strains of flu viruses are circulating, even if a person recovers from H3N2 strain infection, it’s possible for him/her to get infected by other viruses, like influenza B.

According to CDC statistics, this year most people were infected H3N2, but a small portion of people were infected H1N1 and influenza B.

H3N2 and H1N1 are strains of influenza A.  Getting sick of one type of influenza A viruses might provide mild protection of other type of influenza A viruses, but it probably doesn’t provide any protection on influenza B.

Therefore, for people recoved from flu, vaccine is still recommended.
