Emerging and re-emerging arboviral diseases in Southeast Asia

Resumo: Arthropod-borne viruses (arboviruses) have become significant public health problems, with the emergence - re-emergence of arboviral diseases nearly worldwide. The most populated Southeast Asia region is particularly vulnerable. The arboviral diseases such as dengue (DEN), Japanese encephalitis (JE), West Nile virus (WNV), chikungunya fever (CHIK), hemorrhagic fevers such as Crimean-Congo hemorrhagic (CCHF) fever, Kyasanur forest disease virus (KFDV), etc. are on the rise - have spread unprecedentedly, causing considerable burden of disease. The emergence/re-emergence of these diseases is associated with complex factors, such as viral recombination - mutation, leading to more virulent - adaptive strains, urbanization - human activities creating more permissive environment for vector-host interaction, - increased air travel - commerce. Climate is a major factor in determining the geographic - temporal distribution of arthropods, the characteristics of arthropod life cycles, the consequent dispersal patterns of associated arboviruses, the evolution of arboviruses; - the efficiency with which they are transmitted from arthropods to vertebrate hosts. The present - future arboviral threats must be mitigated by priority actions such as improving surveillance - outbreak response, establishing collaboration - communication intersectorally, - strengthening the prevention - control programmes along with improving biosafety aspects with regards to highly infectious nature of these arboviral diseases. Evidence from research needs to be generated - priority areas for research defined.
