Background & ObjectivesImproved dengue cost estimates offer the potential to provide a baseline measure to determine the cost-effectiveness of interventions. The objective of this study was to estimate the cost of dengue prevention, treatment and fatalities in Kerala, India, over a period of one year.MethodsThe study was done in Kerala, a southern State in India. Costing of treatment was done from a family perspective. It was found by primary data collection in a sample of 83 dengue patients from Thiruvananthapuram district and estimated for Kerala using the reported number of cases in 2016. Costing of prevention was done from the government perspective for the entire State. In-depth interviews with State programme officers and experts in the field were conducted. The present value of lifetime earnings was used to value lives.ResultsThe cost of treatment of dengue in the State was ₹137 milion (2.16 million US$). The cost of prevention in the State was ₹535 million (8.3 million US$). The cost of fatalities was the highest among costs at ₹1760 million (27.7 million US$). US$ 38 million was the least possible estimate of total cost of dengue. The total out-of-pocket spending (OOPS) of >60 yr was significantly (P<0.05) higher than other age groups. The total OOPS was significantly (P<0.001) higher in private sector compared to public.Interpretation & ConclusionsAlthough deaths due to dengue were few, the cost of fatalities was 12 times more than the cost of treatment and three times the cost of prevention. Focusing on mortality reduction and disease prevention in elderly would be beneficial.
