| Summary: | Over the last few decades, reporting of dengue cases has dramatically spread over almost entire India but the disease burden is grossly under- estimated under the current surveillance system.
This review based on literature searches in PubMed and Medline for the period 1961-2012 describes changing epidemiological patterns, emerging challenges to public health intervention for control of dengue transmission in India and estimates magnitude of under-reporting. The annual reported numbers in 10 selected states/Union Territories with the highest number of cases during the years 2008-2012 and the surveillance system estimated expansion factor of 8.9- 9.6 derived from Thailand and Cambodia data respectively were used for new estimates of dengue morbidity in India.
The reporting incidence of dengue is as low as 4/100,000 in 2012. The estimated crude incidence of dengue for 2012 is 53/100,000 to 58.83/100,000 and the country annual health care facility based case load would be around 700,000. India needs to expand surveillance activities to non-hospitalized cases and to the distribution and abundance of Aedes aegypti throughout country and review state and local vector control activities for Aedes aegypti and Aedes albopictus. Knowledge of vector prevalence is essential to estimate the geographical distribution of dengue infection and associated disease. |
