For some mosquito transmitted diseases, there are no known drug treatments or vaccines, so prevention becomes extremely important. This is certainly true for dengue fever, which occurs widely in the tropical regions.
Dengue (also called break bone fever) occurs about five to eight days after being bitten by an aides mosquito infected with the virus. Classic symptoms include severe splitting headaches, high fever, backache, muscle and joint pains and skin rashes. The symptoms last from five to seven days.
Occasionally, the illness is complicated by a bleeding tendency and is then called dengue hemorrhagic fever, which sometimes can be fatal. In addition to the symptoms mentioned above, patients may also develop bruises and bleeding of the skin, nose and gums. Intestinal as well as other types of internal bleeding can occur.
