The Seroprevalence of Dengue in a Tertiary Care Hospital

Dengue or break bone fever is a deadly disease caused by the Flavivirus. There are approximately 390 million dengue infections every year in the tropical and sub-tropical regions of the world. It is caused by the day biting Aedes mosquitoes which has expanded its geographical boundaries recently. Early diagnosis of Dengue is essential to prevent the complications. The study was done in a tertiary care hospital to have an insight about the seroprevalence during the dry months from March to August. The seropositivity was found to be 33.64% with the maximum number of cases in the 21-30 years age group (37.57%). The number of cases recorded was the highest in the month of August. 62.98% of cases were due to primary Dengue. The study highlights the importance of mosquito control measures all the year round and not just during the monsoon season.
