Socio-economic and environmental determinants of dengue and chikungunya transmission: GIS for surveillance and epidemic control - A systematic review

Masimalai Palaniyandi

Abstract :

The geographical distribution and seasonal variations of dengue and chikungunya vector abundance and epidemic transmission have completely been controlled by the socio–cultural, economic, and the environmental variables. Dengue and chikungunya, are arboviral infections transmitted mainly by Aedes aegypti and Ae. albopictus mosquitoes, and emerging as the most important mosquito–borne viral disease, [N1] having a worldwide distribution in tropical and many subtropical areas. The disease is becoming endemic mainly in tropical regions, where the expansion of urban populations, impoverished and crowded areas, and poor infrastructure create ideal habitats for vector proliferation and consequent spread of the virus. Dengue and chikungunya are seasonal disease (in general), whose incidence increase during the months of highest temperature [N2] and precipitation. The dengue epidemic is spatially associated with socio–cultural, economic, and environmental determinants and the context varies according to different geographical areas. Geographical information systems (GIS) based systematic housing and population survey with aid of GPS has been used to collect data pertaining to risk factors affecting dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS), and its association with vector distribution. The spatial distribution of the dengue fever is determined by the geographical extent of the vector or reservoir hosts and their habitat priorities. Change in land–use permits the colonization of new habitats and is strongly related to the dengue incidence. The Aedes aegypti mosquito, a primary vector of dengue is now present in > 20 European countries. The other vector species contributing to dengue outeaks include Ae. albopictus. [N3] A GIS based rapid entomological survey and active community participation for vector eeding source reduction, and web mapping GIS for permanent dengue surveillance could be used to grip the epidemic successfully
