The symptoms, following an incubation period of five to eight days, are fever, chills, severe headache, pain in the joints, sweating, and prostration. Symptoms subside in two to four days, but after a remission lasting from a few hours to two days there is another rise in temperature, and a generalized rash appears.
Convalescence is sometimes prolonged, with weakness and low blood pressure.
Dengue hemorrhagic fever, a severe form of the disease, can cause hemorrhage, shock, and encephalitis. It is a leading cause of death among children in Southeast Asia and in recent years has become increasingly prevalent in tropical America. There is no specific treatment for dengue fever except good nursing care. The disease can be controlled by eradicating the mosquitoes and destroying their breeding places.
