Clinical dengue fever begins with sudden onset of high fever, myalgias and retro-orbital headache that typically increases with eye movement. Patients may also experience a metallic taste, minor bleeding problems and rash, particularly at the conclusion of the illness. Severe hemorrhage and encephalitis are rare complications. Dengue hemorrhagic fever may develop in children and adolescents, and can lead to death through hemorrhage and intravascular volume depletion. The diagnosis of dengue fever is clinical, supported by the laboratory finding of a rise in specific IgM titers.
Treatment is symptomatic and supportive.
Public health measures to control mosquitoes and relieve overcrowding are essential to prevent further spread of dengue fever. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference.
