How is dengue contracted?

It comes from a virus (the dengue virus) carried by the striped Aedes aegypti mosquito. The mosquito flourishes during rainy seasons but can breed in water-filled flower pots, plastic bags and cans year round. One mosquito bite can inflict the disease. The incubation period ranges from 3 to 15 (usually 5 to 8) days before the signs and symptoms of dengue appear.

Dengue fever is a disease caused by a virus that is transmitted by mosquitos. It is an acute illness of sudden onset that usually follows a benign course with headache, fever, prostration, severe joint and muscle pain, swollen glands (lymphadenopathy) and rash. The presence (the "dengue triad") of fever, rash, and headache (and other pains) is particularly characteristic of dengue.

Dengue (pronounced DENG-gay) is now reaching the peak of a roughly five-year cycle. It strikes people with low levels of immunity. An attack of dengue produces immunity for a year or more. Once this outbreak ebbs, more people will be resistant to the viral disease and the cycle will begin again.

Dengue goes by other names including breakbone or dandy fever. Victims of dengue often have contortions due to the intense joint and muscle pain. Hence, the name "breakbone fever." Slaves in the West Indies who contracted dengue were said to have "dandy fever" because of their postures and gait.
