Addition
Chikungunya fever is an acute viral infectious disease characterized by high fever, general intoxication, and hemorrhagic manifestations. It belongs to arboviral infections and is classified as one of the so-called "neglected tropical diseases." The disease is included in the list of major "travelers' diseases."
Chikungunya fever is not endemic to mainland EU/EEA. Most cases are imported. However, in regions where Aedes albopictus mosquitoes are present, local spread of the virus is possible under favorable conditions. Such cases have been recorded since 2007. Cases of this infection being imported have also been recorded in Ukraine.
The optimal average daily temperature for Chikungunya virus transmission in a temperate climate is 24–26 °C, with a possible range of 12–30 °C. Historically, Chikungunya virus was considered a potential biological weapon agent.
