Objective: To know the prevalence of dengue arboviral infection in and around Bellary district.
Material and Methods: The laboratory records of clinically suspected dengue patients from January 2009 to December 2011were analyzed retrospectively and results of Ig M anti dengue antibodies tested by Ig M capture enzyme linked immunosorbant assay (Mac ELISA).
Results: A total of 1396 dengue suspected serum samples were analyzed, out of which 160 (11.46%) samples were found positive for dengue virus infection. Maximum positive cases were seen in 2009 (15.72%). The present study emphasizes the continuous sero-epidemiological surveillance for the effective dengue arboviral infection control programme.
