Dengue is a mosquito-borne viral disease that spreads widely in the monsoon season. It is transmitted by the infective bite of the Aedes Aegypti mosquito.
The symptoms of dengue include high fever, headache, rash, muscle and joint pain. It occurs in two forms – Dengue fever and Dengue Haemorrhagic Fever (DHF). Dengue fever is a severe, flu-like illness while DHF is a more severe form of the disease, which may cause death.
