A RETROSPECTIVE STUDY TO DETECT DENGUE INFECTION IN UNSUSPECTED FEVER CASES
Dengue is endemic in Kolkata, India. Outbreaks of dengue cases often occur regularly at short intervals. This retrospective seroepidemiological surveillance was conducted longitudinally. Dengue cases were diagnosed in the laboratories from suspected patients by dengue specific IgG, IgM antibodies and NS1 antigen, from suspected persons to investigate, analyze and categorize the cases who were actually suffering from dengue to diagnose a dengue patient in the laboratory practice along with the status of the patient related to the detection of disease and duration of primary and secondary infection for effective monitoring of the patient. Age and Sex of the dengue patients were determined. Detection of dengue in unsuspected fever cases in unfavorable transmission season was evaluated. The transmission of dengue infection in the non-transmission season is not remarkable and often remains submerged. Proper measure at this stage may prevent the epidemic outbreak in the transmission season. This sort of experience will help to enrich the effective control and case management of the menace.
