dengue fever

(dĕng`gē, –gā), acute infectious disease caused by four closely related viruses and transmitted by the bite of the female Aedes mosquito; it is also known as breakbone fever and bone-crusher disease. The disease occurs in both epidemic and sporadic form in warm climates (S United States, South America, the E Mediterranean countries, India, and especially SE Asia and the W Pacific). The classic symptoms, following an incubation period of five to eight days, are high fever, chills, severe headache, pain in the joints, pain behind the eyes, rash, sweating, and prostration, but infected persons may experience milder symptoms. 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 can occur when a person who has acquired immunity to one of the viruses that cause dengue fever is infected by a different dengue virus; antibodies to the first dengue infection apparently work to aid the second virus. 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. Both diseases can be controlled by eradicating the mosquitoes and destroying their breeding places. The mosquito population also has been controlled through the release of sterile male mosquitoes and the release of mosquitoes infected with bacteria that makes the insects incapable of transmitting viruses.

Dengue fever

[′deŋ·gē ‚fēv·ər]
An infection borne by the Aedes female mosquito, and caused by one of four closely related but antigenically distinct Dengue virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4). It starts abruptly after an incubation period of 2-7 days with high fever, severe headache, myalgia, and rash. It is found throughout the tropical and subtropical zones. Also known as break-bone fever.

Symptoms of classical dengue fever include sudden high grade fever, headache, retro bulbar pain, severe pain in muscles and joints, nausea, vomiting and skin rash.
In the case of hematocrit increase, since hemoconcentration and plasma overflowing are symptoms of HDF and not determining factors of classical dengue, the hematocrit did not seem altered in the females under analysis.
Regarding DF clinical presentation, most of the physicians knew correctly that they should suspect DF in patients presenting with retro-orbital pain, general body aches, and fever (84.1%); persistent vomiting and abdominal pain are warning signs of severe dengue (81.2%), and the classical dengue rash typically does not appear on the same day of fever (71%).
(1-4) The infection by either of four DENV serotypes-1 to 4 may be asymptomatic or may present as undifferentiated acute febrile illness, classical dengue fever (DF) or as severe dengue-Dengue hemorrhagic fever (DHF) or Dengue shock syndrome (DSS) where the mortality rate is approximately 1-2.5%.
The clinical manifestations reported in this study illustrate the difficulty in differentiating chikungunya infection from classical dengue fever but may help to differentiate this infection from other causes of febrile exanthcma in travelers.
