Dengue fever which is also known as bone breaking fever, is an infectious tropical disease caused by the dengue virus. Symptoms of the virus include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles.
In a small proportion of cases the disease develops into the life-threatening Dengue Outbreaks hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or a state where dangerously low blood pressure occurs.
Dengue is transmitted by several species of mosquito. The virus has four different types; infection with one type usually gives lifelong immunity to that type, but only short term immunity to others. Subsequent infection with a different type increases the risk of severe complications. As there is no vaccine, prevention is sought by reducing the habitat and the number of mosquitoes and limiting exposure to bites.
Treatment of acute Dengue Outbreaks us supportive, using either oral or intravenous rehydration for mild or moderate disease, and intravenous fluids and blood transfusion for more severe cases.
