Dengue virus is a mosquito-borne flavivirus and one of the most prevalent arbovirus in tropical and subtropical regions of the world. Dengue virus infection has emerged as notable public health problem in recent decades especially in the tropical and subtropical countries because of high mortality and morbidity associated with it. The study was performed in the record department of Medical College & Hospital, pune over a period of three years (From January 2014 to December 2016) with2490 clinically suspected patients attending the hospital & suffering from fever for at least five days. Blood was collected aseptically from suspected cases, serum was separated and analyzed by IgM capture ELISA technique to detect Dengue specific IgM antibodies. In this study, the highest numbers of cases (57.31%) were recorded in the age group 10–29 yrs with male preponderance and majority belonging to urban area. In present study the positivity rate of the dengue positive cases were decreasing over study period from 24.04% to 11.92%. A seasonal variation is also observed as there is an increasing no. of cases from July onward i.e. monsoon period in months from August to November. The no. of cases started rising from August and peaks at October, during all three years of the study. Community awareness, early diagnosis and management and vector control measures need to be strengthened in order to reduce the increasing number of dengue cases. Special preventive strategies should be planned during post monsoon period. Every case of fever should visit physician immediately to prevent complications, in rural as well as urban areas.
