Abstract: Dengue virus is a positive sense RNA virus of the flavivirus family with at least four distinct serotypes. It is the cause of dengue fever which is associated with headache, retro-orbital pain, joint and bone pain (hence "breakbone fever"), fever and rash. The most serious form of dengue infection is known as dengue hemorrhagic fever which is characterized by thrombocytopenia and potentially multi-system organ failure. Dengue is a mosquito-borne viral illness that is spreading rapidly to become endemic in tropical and subtropical regions of the world. Infection with one serotype results in long-term immunity only to that specific serotype, and not to the others therefore a person can be infected many times with the virus. Dengue often is difficult to diagnose, and a presumptive diagnosis is established initially based on clinical signs and symptoms, while waiting for laboratory confirmation.
