Dengue (pronounced DENG-gay) fever is a disease caused by a family of viruses that are transmitted by mosquitoes. It is an acute illness of sudden onset that usually follows a benign course with headache, fever, severe joint and muscle pain, swollen glands and rash. The presence (the "dengue triad"), rash, and headache (and other pains) is particularly characteristic of dengue.
Dengue (strikes people with low levels of immunity. Because it is caused by one of three virus, it is possible to get dengue fever multiple times. Therefore, an attack of dengue produces immunity for a lifetime to that particular which the patient was exposed.
Dengue goes by other names, including "breakbone fever." Victims of dengue often have contortions due to the intense joint and muscle pain, hence the name dengue fever. Slaves in the West Indies who contracted dengue were said to have dengue fever because of their postures and gait.
Dengue fever is chronic form of the viral illness. Manifestations include headache, fever, rash, and evidence of hemorrhage in the body. Petechiae (small red or purple blisters under the skin), bleeding in the nose or gums, black stools, are all possible signs of hemorrhage. This form of dengue fever can be life-threatening or even fatal
