Introduction: Arboviruses are growing concern for state and central health authorities in India. Prevention of arbovirus infections or to break the chain of infection valuable strategy is by vector control measures. However, it's not effective to control the country's mosquito population. The primary aim of this study was to analyse the epidemiology and demographic characteristics of dengue and chikungunya. Materials And Methods: In this prospective study patients presenting with clinical features suggestive of dengue and chikungunya data was collected. Specimens about 5 ml of blood from each patient were collected for serological testing. Results: The mean age of dengue and chikungunya positive patients was 34.8±2.34 and 43±4.21 respectively with a slight male predominance. Dengue confirmed cases count increased in August and September and more number of cases was noted from November to January. Whereas, Chikungunya confirmed cases didn’t show any much seasonal variation during the studied years. 49.7% positives were detected as IgM antibodies, 28.57% were tested as NS1 antigen positive and remaining 21.6% positives were detected as both NS1 and IgM antibodies. Conclusion: South India region is endemic for dengue & chikungunya, research studies on incidence, demographic parameters and transmission dynamics will be useful for central and state government authorities to implement protocols like vector control measures, early diagnostic testing and health education at higher level.
