General Information about Influenza
Influenza (the flu) is a contagious respiratory illness caused by the influenza virus. Each year there are usually 2 strains of Influenza A virus (H1N1 and H3N2) and one predominant strain of Influenza B that circulate. The flu season in the U.S. usually starts in the late fall, peaks in January/February, and continues through the early spring. The flu season arrived one month earlier than usual this year (November 2012), with the more virulent influenza A (H3N2) being the predominant circulating strain.
