Dengue is a vector borne Arboviral disease spread by Aedes mosquitoes.  Four serotypes are recognized 1All four serotypes are prevalent in our country2.

Aim of the study:

To find the prevalence of the dengue infection based on age, sex, seasonal distribution of the disease. Acute infection is detected by detecting both NS1 antigen & IgM antibody.

Methods:

This is a retrospective study of one year duration from January 2018 to December 2018. The serum sample from 1400 suspected cases of dengue were subjected for the ELISA test to see IgM antibody and NS1 antigen.

Results:

Out of 1400 cases tested 216(15%) were positive for dengue by IgM ELISA, 1184(85%) were negative, 4 (0.2%) were positive for both IgM antibody and NS1 antigen

Conclusion:

So early and specific serological marker coinciding with day of illness should be done to diagnose dengue infection.
