Trends of dengue viral infection among clinically Suspected cases in allahabad, india

Abstract

Dengue virus infection is a major public health problem in India.  This study was carried out for the period of three years to find out the incidence of dengue virus in a tertiary care hospital at Allahabad, District of Uttar Pradesh India and its association with seasonal, gender and age factors. The study was conducted in Microbiology department of tertiary care hospital of Allahabad district, U.P, India. A total of 2463 blood samples were analyzed for dengue specific IgM antibody, by ELISA method.  The demographic details were collected in a structured proforma. Analysis was performed using statically package SPSS version 17.0 IBM USA. A total of 792/2463(32%) patients were tested positive for dengue IgM antibody. Of the total positive dengue cases, maximum (63%) numbers were from the year 2015 and highest number of transmission was observed in the month of October in all the three years study duration. Male population was more affected (77.50%) than female population and age group 21-30 (41%) was the most affected compared to other age groups. Dengue transmission is augmented in central India. Since young male population was most affected, hence protective measures should be taken by this age group. As vaccines or antiviral drugs are not available for dengue viruses; the only effective way to prevent dengue is to control the mosquito vector, Aedes aegypti and prevent its bite.
