Guidelines for prevention and control of chikungunya fever
Chikungunya is an emerging, epidemic-prone vector-borne disease of considerable significance in the WHO South-East Asia Region. Massive outbreaks of chikungunya fever have occurred in recent years in India and in the island countries of the Indian Ocean. Socioeconomic factors and public health inadequacies that facilitated the spread of this infection in the past continue to exist. Environmental factors and community behaviours plays a significant role in chikungunya outbreak and spread. Specific treatment is not available and there is no vaccine to prevent chikungunya. The socioeconomic burden of the disease can be devastating in the outbreak areas due to very high attach rate affecting a large proportion of the population. Vector control is the only public health strategy to prevent and control the outbreaks. Strategy of integrated vector management is necessary to tackle the vector. The guideline elaborates on the prevention and control strategy developed by the South-East Asia Regional Office of WHO, which consists of six key components including integrated vector management (IVM).
