Chikungunya fever is a viral infection transmitted by mosquito bites. Symptoms include fever, joint pains, muscle aches, headache, and rash. The disease is almost never fatal, but may be complicated by protracted fatigue, malaise, and joint pains, chiefly involving the wrists, ankles, and fingers. Laboratory abnormalities may include low platelet counts and elevated liver enzymes. The diagnosis is confirmed by blood tests, usually an immunocapture ELISA, which show the presence of antibodies against chikungunya virus. Rarely, the infection is complicated by meningoencephalitis, which is usually seen in newborns and those with pre-existing medical conditions. There is no vaccine at present. Travelers may reduce their risk by keeping themselves covered, applying insect repellent, and taking other measures to prevent mosquito bites. Because of the risk of mother-to-child transmission, pregnant women need to take special care to protect themselves from mosquito bites.
