Global influenza update (World Health Organization)

Influenza activity in the northern hemisphere temperate countries decreased to low levels. Influenza activity also decreased in most regions of tropical Asia except for Sri Lanka and Vietnam where flu activity (influenza A) continued increasing. In Central America and the Caribbean, influenza activity remained low, except in Cuba and the Dominican Republic where increasing flu activity was reported. Influenza activity in the southern hemisphere started to increase slightly in South America and in South Africa but remained low in Oceania.

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. Vaccination against influenza is recommended where flu virus activity is high, especially if a person is over 65 years old with a chronic medical condition.
