Chikungunya virus disease

Chikungunya virus is a mosquito-borne alphavirus found in Africa, Asia, and Europe. In late 2013, locally acquired cases appeared for the first time in the Americas on the Caribbean island of St. Martin, and the virus subsequently has spread throughout Central and South America. The virus is transmitted by the same Aedes spp. mosquitoes (Ae. aegypti and Ae. albopictus) that also transmit dengue and Zika viruses.

Unlike many other mosquito-borne viruses, most people who are infected with chikungunya develop symptoms. The most common symptoms are fever and joint pain, but patients may also experience headache, muscle aches, or rash. Symptoms usually begin 3-7 days after a person is bitten by an infected mosquito, and most recover within a week. Joint pain may persist for weeks to years after the initial illness.
