Spatial risk mapping for Dengue fever using GIS: A case study of Hyderabad.

There is compelling evidence that changes in the climate of the earth occur which cannot be explained without taking into account human influence. Many vulnerability studies anticipate climate change will lead to increased occurrence of transmittable diseases, including Vector Borne Diseases (VBDs). VBDs are spread by the bite of infected mosquitoes and other insects (vectors). The breeding of species of mosquitoes is strongly associated with demographic factors. Mosquito populations and mosquito density is considered to be the key signs that determine and evaluates risk of dengue in any particular area. Measuring the population of mosquitos requires enormous exertions and use of the latest information ICT techniques. The incidents of dengue can be prevented by timely decision to implement vector control activities. Recent advances in Geographic Information System (GIS) and mapping new technologies have shaped novel opportunities for public health managers to improve, plan, monitor and assess health systems. GIS represents better explanation and analysis for the spread and control of such vector borne diseases. This study used GIS application to identify areas prone tosuch diseases. The results show that Latifabad is a major area prone to VBD followed by Bhitainagar, Qasimabad and Heerabad. The ability to identify likely areas of dengue incidence helps for quick and efficient disease supervision and prevention practices.
