Dengue fever is a disease caused by a family of viruses that are transmitted by the bite of a striped Aedes aegypti mosquito. Dengue hemorrhagic fever is a more severe form of the viral illness. Manifestations include headache, fever, rash, and evidence of hemorrhage in the body.
Dengue fever should not be confused with Dengue hemorrhagic fever, which is a separate disease that is caused by the same type of virus but has much more severe symptoms.
Symptoms of dengue are:
* Sudden high fever after 4-7 days of infection.
* Occurrence of rashes 2-5 days after fever.
* Increased skin sensitivity.
* Headache (especially behind the eyes)
* Joint aches
* Muscle aches
* Swollen lymph nodes
If you have sudden high fever then you must consult a dengue specialist doctor to get yourself tested and diagnosed for dengue infection. In a small proportion of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
