dengue is carried by aegis egypty, a low flying, black and white-spotted mosquito. When it bites you, the virus it carries will travel your bloodstream causing you to have dengue.



Dengue fever is a benign acute febrile syndrome occurring in tropical regions, which is the most important mosquito (Aedes aegypti), transmitted viral disease. The virus causes Dengue shock syndrome in 20-30% of infected cases. There are four types (known as "serotypes") of dengue.
Infection and recovery from one type of dengue does not protect a person from another type. Dengue Hemorrhagic Shock Syndrome (DHSS) is a dangerous implication in which fever is followed by the collapse with shock, decreased blood pressure and signs of hemorrhage. The shock increases the production of the hormone adrenaline, which in turn increases the heartbeat. Blood is pumped faster resulting in more hemorrhage and the heart becomes overworked. Dengue infection weakens the wall of the blood vessels resulting in plasma leakage; disease suppresses the production of platelets that help in the clotting of blood. If the process continues unchecked, the volume of blood decreases due to leakage, the blood pressure drops and the platelet count reduces. Bleeding occurs in patients with severe shock syndrome. "The fever lasts about seven days and the patient has severe body ache. It's in fact known as a bone-breaking fever. But dengue hemorrhagic fever is a far more serious condition, which generally occurs in patients who have already experienced dengue," explains Dr Pradeep Seth,
