If dengue is not severe enough, it causes high fever, rash, muscle and joint pain but if it is severe it can cause severe bleeding, sudden drop in blood pressure and death. Dengue hemorrhagic fever is called severe dengue fever. According to the Directorate of National Vector Borne Disease Control Program (NVBDCP), there have been more than 67,000 cases of dengue fever in India as of 13 October 2019. There are about 12,756 cases reported in the state of Karnataka. In the states and union territories of India, dengue is endemic. It has been observed that due to floods and monsoon season, there is a high probability of dengue outbreak due to rain in some states.

The Aedes aegypti mosquito originated in Africa, but is also found in tropical regions around the world. When a mosquito is infected with the dengue virus and bites a person, the virus enters the mosquito. When this infected mosquito bites another person, the virus enters the person's bloodstream.
According to the World Health Organization, the vaccine itself is not an effective tool to reduce dengue fever in areas where the disease is common. It is necessary to control the mosquito population and human exposure which is the most important part of preventive efforts. To prevent dengue, it is important to avoid mosquito bites.
