Abstract
Dengue is a mosquito borne viral fever transmitted by Aedes aegypti and albopictus mosquito. The globally estimated burden of symptomatic cases ranges to 96 million and 58.4 million cases/year). The estimated mortality amounts 2.5% and the endemicity is spread around 128 countries of the world. The aim of our study is to identify the prevalence of dengue to the patients reporting to our tertiary care hospital in Puducherry. A prospective crosssectional study was conducted at our tertiary care hospital in Puducherry. The study was conducted over a period of 4 years from January 2013 to December 2016. The serum samples were tested by Rapid immunochromatography test. Around 272 (12.3%) cases of both primary and secondary dengue were identified. The age wise distribution of cases showed more cases in 21 to 30 age group (38.6%). The seasonal distribution shows more cases were present from September to January. There was a gradual increase in the positive cases from 2013 onwards with a peak during 2016. Being a persistent viral infection a proper vector control measure, concomitant monitoring on the Seroprevalence of dengue among the population is needed.
