Abstract :

Background: Dengue virus belongs to family Flaviviridae, having four serotypes that spread by the bite of infected Aedes mosquitoes. It causes a wide spectrum of illness from mild asymptomatic illness to severe fatal dengue haemorrhagic fever/dengue shock syndrome (DHF/DSS). Approximately 2.5 billion people live in dengue risk regions with about 100 million new cases each year worldwide. The incidence of dengue has increased 30–fold over the last 50 years. Methodology: This survey study is designed to find out relationship of dengue fever with climatic factor such as rainfall, temperature and humidity during the period of five months (i.e. August 2016 to December 2016). Results: Total 1226 samples were analyzed for serological test of dengue. 154 (12.56%) found to be positive for dengue test including 108 male and 46 female cases. Maximum number of dengue cases reported was in 21–30 years age group. Maximum positive cases were detected in November. Conclusion: Dengue is one of the major public health problems in India. A large number of cases are reported in the monsoon and post–monsoon period. Preventive measures should be taken both at personal and government level to reduce morbidity and mortality from dengue. < clear="all" style="page–eak–before:always; mso–eak–type:section–eak" />
