Dengue virus belongs to family Flaviviridae that spreads by the bite of infected Aedes mosquitoes.
Approximately, 2.5 billion people live in Dengue risked regions with about 100 million new cases each year worldwide.
The cumulative Dengue disease burden has attained an unprecedented proportion in the recent times with a sharp increase in the size of the human population at risk.
In India, the first epidemic of clinical Dengue-like illness was recorded in Chennai in 1780 and the first virologically proved epidemic of Dengue fever occurred in Kolkata in 1963-1964.
During the last 50 years, a large number of physicians have treated and described Dengue disease in India and a few scientific studies addressing various problems of the Dengue disease have been carried out. Achievements of Indian scientists are considerable.
This research briefly reviews the extent of work done by the various groups of scientists in this country.
