An outbreak of chikungunya virus is currently ongoing in many countries in Indian Ocean sinceJanuary 2005. The current outbreak appears to be the most severe and one of the biggest outbreakscaused by this virus. India, where this virus was last reported in 1973, is also amongst affectedcountries. Chikungunya virus has affected millions of the people in Africa and Southeast Asia, sinceit was first reported in 1952 in Tanzania. Even then, natural history of this disease is not fully understood.The intra-outbreak studies, point towards recent changes in the viral genome facilitatingthe rapid spread and enhanced pathogenecity. The available published scientific literature on chikungunyavirus was searched to understand the natural history of this disease, reasons for the currentoutbreak and the causes behind re-emergence of the virus in India.The paucity of the scientific information on various epidemiological aspects of chikungunya virusthreatens off an epidemic as control of spread of virus might be difficult in the absence of appropriateknowledge. There is an immediate need of the research on chikungunya virus, for an effectivevaccine besides strengthening the existing diagnostic laboratory facilities. The current outbreak canalso be taken as a lesson for establishment of a system for continuous surveillance of diseases, considereddisappeared from the countries. The re-emergence and epidemics are unpredictable phenomenabut the impact of such events can be ameliorated by appropriate knowledge and by being in theright state of preparedness |
