Influenza viruses are transmitted from person to person by inhaling small airborne respiratory droplets created when infectious persons cough, sneeze or laugh. These viruses are also spread by hand-to-hand and hand-to-mouth contact. Maintaining a small distance (1 meter) from a person with a respiratory illness and frequent hand washing will help reduce the risk of exposure. This year, the currently available vaccine provides a fair degree of protection (up to 65%) against the currently circulating influenza viruses.
