Dengue virus - Wikipedia- Deng Mosquito è spento ,Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. Five serotypes of the virus have been found, all of which can cause the full spectrum of disease.

miR-252 of the Asian tiger mosquito Aedes albopictus regulates dengue virus replication by suppressing the expression of the dengue virus envelope protein. Yan H, Zhou Y, Liu Y, Deng Y, Chen X. The Asian tiger mosquito, Aedes albopictus isa major vector of dengue in mainland China.
The symptoms of these three mosquito-borne diseases are very similar, which makes the diagnosis more difficult. However, there are few differences that can be used to distinguish the disease and avoid misdiagnoses. There is no cure for these virus diseases, the treatment consists on relieving the symptoms and a proper clinical management can improve outcome.
