Global flu (influenza) summary

The World Health Organization has reported that flu virus activity in the northern hemisphere temperate zones has remained low during the summer season. In most regions of tropical Asia, influenza activity also decreased. In the Caribbean region of Central America and tropical South America, the flu season appears to have ended. .

In temperate countries of South America and in South Africa, flu activity peaked in late June 2013. In Australia and New Zealand, the number of influenza viruses detected and the rates of influenza-like illness were lower than those at the same time in previous years. However, there was an increasing trend since early August.

Flu (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.
