Global flu (influenza) activity (summary)

Northern hemisphere temperate zones - influenza activity is low as expected during the summer season.
Tropical Asia - influenza activity has decreased, except in India and Vietnam where influenza A activity remains relatively high.

Southern hemisphere - influenza activity is increasing considerably in South America (especially in Brazil and Venezuela) and in Southern Africa.

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.
