Abstract

Vector borne diseases are having increasing trend in both vertical and horizontal structure of the disease
epidemics in India for the recent decades. Filariasis, Japanese Encephalitis, Dengue, Chikungunya,
Leishmaniases, and Malaria are the major vector borne diseases in India for several decades. The increasing
trend of both spatial distribution and magnitude of the disease makes public health challenging problem
in India, especially, for the recent decades. The both spatial extent and magnitude of vector borne disease
outbreaks have been increasingly reported and it has been found ubiquitous across the country. The
geographical extent of endemic regions, the frequency of outbreaks in both urban and rural, and the spatial
and temporal aspects of vector borne disease epidemics were analyzed across the nation for the past 30
years, in order to assess the probability of potential risk of the VBD outbreaks in the country using GIS,
accordingly, the appropriate control strategy will be prepared to manage the future epidemic situations in
a site specific areas of high risk hotspot regions. Spatial and temporal dynamics of vector-borne disease
epidemics across the country have been evidently associated with land use / land cover changes including the
agriculture practices, urban dynamics, industrial growths, population movements, manmade environmental
transition, etc., and have been acted upon the epidemic scenarios change the indigenous territories, and
also intrusion into the non-endemic areas. The concept of control activities of vector borne disease sudden
occurrence could not be achieved with no single intervention will be sufficient to control epidemic diseases,
and therefore, prevention measures and control strategy must have to be advantageously applied during the
intermittent outbreaks situations regularly, so as to move towards the achievement of erratic transmission
control and prevent acceleration in epidemic transmission early in advance successfully.
