Dengue is the most common and widespread arboviral infection in the world today. It is an increasingly prevalent tropical arbovirus infection with significant morbidity and mortality. Dengue fever is a recurrent problem in West Bengal.The purpose of this study is to present a comprehensive report on the diagnosis of Dengue fever cases with age and sex preponderance, data available from January 2013 to December 2016 at Malda Medical College, Malda, West Bengal. This is a cross-sectional investigative study done at Malda Medical College. In suspected Dengue fever cases, serum samples were tested for presence of Dengue NS1 antigen and presence of Dengue specific IgM antibodies by IgM antibody capture enzyme linked immunosorbent assay (MAC ELISA), strictly following the manufacturer’s protocol.On the year 2013, 2014, 2015 and 2016 Dengue confirmed cases were 25, 33, 68 and 1102 respectively. The number of Dengue cases in 2016 clearly outnumbered the Dengue cases in 2013, 2014 and 2015. In our study the highest numbers of cases were recorded in the age group 11 to 30 years and males were more affected than females. The majority of the cases were reported during the monsoon and post monsoon seasons.Dengue is increasing its geographical areas mostly everywhere now and this Dengue epidemiology demands efforts and support for controlling the disease effectively.
