Dengue fever 

Dengue fever (DB) is an acute febrile disease caused by dengue virus, which enters the human bloodstream through a mosquito bite.

Causes of dengue fever:

Aedes aegypti is the vector of dengue virus causes dengue fever.The main cause is a viral disease dengue hemorrhagic fever,which is a virus of the family Flavivirida. Symptoms of dengueemerging as someone who has been infected by one of four types of dengue virus infection by different types of dengue virus.Immune system that has been formed in the body after the first infection would likely result in the emergence of a more severedisease symptoms when infected for a second time. A personcan be infected by at least two types of dengue virus during the lifetime, but the same type of virus can only infect one-time due to the body's immune system is formed.

Dengue virus can enter the human body through the bite of the carrier vector, the Aedes mosquito of the genus such as Aedes aegypti and Aedes albopictus females. Aedes aegypti is thevector of the most common cause of this disease. Mosquitoescan carry the dengue virus after sucking the blood of people whohave been infected with the virus. After an incubation period ofvirus in mosquitoes for 8-10 days, an infected mosquito can transmit dengue virus to humans healthy bite. Female mosquitoes can spread the dengue virus is carried to theoffspring via the egg (transovarial).


Finally, the level of risk of contracting dengue fever increased to a person who has antibodies to dengue virus infection due to the first. In addition, the risk of dengue fever were also higher in women, someone who is younger than 12 years
