Chikungunya fever is a mosquito-borne viral disease caused by the chikungunya virus. The disease has been identified in over 110 countries in Africa, Asia, Europe, the Americas and islands in the Indian and Pacific Oceans.
Symptoms are generally self-limiting and last for a few days. Most patients recover fully. Joint pain may persist for several months or even years, but severe symptoms and deaths are rare.
In Hong Kong, Aedes aegypti is not found, but Aedes albopictus is commonly found. These mosquitoes bite throughout daylight hours with peaks in early morning and late afternoon.
