Dengue Fever

Every year, more than 390 million dengue infections are reported from across the world, with around 96 million resulting in illness. The four kind of viruses that causes dengue are DEN-1, DEN-2, DEN-3 and DEN-4. As per the National Vector Borne Disease Control Programme (NVBDCP), around 1.30 lakh cases and 245 deaths were reported across the country due to dengue in 2016. High fever, rashes in skin, headache, muscle and joint pain are some of the common symptoms of Dengue Fever, say health experts at AMRI Hospital, known as best hospital in Eastern India.

West Nile Virus

Caused by Culex mosquitoes, West Nile Virus causes a fatal neurological disease in humans. It is widely spread in African countries, Europe, the Middle East, North America and West Asia. Humans, horses and other mammals are likely to be infected from West Nile Virus. Common symptoms include severe headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis.


Malaria is said to be one of the most severe mosquito-borne diseases, which claims more than 600,000 lives every year. It is mainly caused by a Plasmodium parasite and transmitted to humans through the bite of the Anopheles mosquito. A sensation of cold with shivering, fever, headaches, vomiting, abnormal bleeding and signs of anemia are some of the most common symptoms of malaria.


A viral mosquito-borne disease transmitted to humans by infected mosquitoes, Chikungunya is one of the deadliest diseases, mainly found in Africa, Asia and the Indian subcontinent.
