Deep vein thrombosis (DVT) occurs when a blood clot develops in a vein deep in the body. Blood returns to the heart through veins. When the blood clumps together and turn into solid material, it is called a blood clot. When the clot is in the deep vein it is called Deep Vein Thrombosis (DVT).
Dengue fever is caused by the dengue virus. The virus is spread by the Aedes mosquito, which also transmits Zika and Chikungunya viruses. Dengue fever has been discovered as a major source of sickness in mosquito-infested locations around the world. Dengue virus is divided into four varieties, each of which can infect you four times over your lifetime.
