Dengue Fever Information

Dengue Fever is a type of fever caused by an RNA virus(flavivirus) and transmitted by the Aedes Aegypti. In order to understand how dengue fever is transmitted, several terms need to be defined. The word "host" means an animal (including a human) that can be infected with a particular disease. Dengue hemorrhagic fever is a severe, often fatal, complication of dengue fever which is spread by the bite of an Aedes mosquito. The mosquito transmits the disease by biting an infected person and then biting someone else. Because this illness may lead to potentially severe complications, you should contact your doctor immediately if you suspect that you have dengue fever. With a diagnosis of Dengue fever, it is also important to consider whether there is an underlying condition causing Dengue fever.

Dengue fever can occur when a mosquito carrying the arbovirus bites a human, passing the virus on to the new host. Most dengue infections result in relatively mild illness, but some can progress to dengue hemorrhagic fever. With dengue hemorrhagic fever, the blood vessels start to leak and cause bleeding from the nose, mouth, and gums. Bruising can be a sign of bleeding inside the body. There are no medications available that can cure dengue fever. Treatment addresses the symptoms and attempts to avoid potential complications. However, in some cases a person may have already had dengue fever at one time, recovered, and then is reinfected with the virus. In these cases, the first infection teaches the immune system to recognize the presence of the arbovirus.
