title: Chikungunya virus infection, a threat to public health.
abstract: Many countries in the world have reported human infections by chikungunya virus (CHIKV) a mosquito-borne togavirus belonging to the genus alpha virus. After half a century of focal out breaks of acute febrile poly arthralgia, the disease had spread unexpectedly in the past decade with large outbreaks in Africa around the Indian Ocean and in Bangladesh. In Asia, CHIKV is thought to be transmitted by the same mosquito as dengue, Aedes aegypti and Aedes albopictus. Due to similarities in clinical presentation with dengue, limited awareness and a lack of laboratory diagnostic facilities, CHIKV is probably often under diagnosed or misdiagnosed as dengue. Treatment is supportive. The prognosis is generally good although some patients experience chronic arthritis. There is no vaccine or antiviral therapy against CHIKV. Early identification of disease and control of vector will prevent the spread of disease.
