Dengue Clinical Symptoms:
- Clinical disease from dengue ranges from self-limited classic dengue fever to life-threatening dengue hemorrhagic fever with shock syndrome.
- Dengue is symptomatic in at least 80 percent of adults, while infections in children tend to produce either no symptoms or only mild symptoms.
- The incubation after the bite of an infected mosquito is three to fourteen days.
Classic Dengue Fever:
- Patients classically have fever, headache, retroorbital pain behind the eyes, myalgias (muscle pain), and arthralgias (bone and joint pain). For this reason, it has been called "break-bone fever."
- A maculopapular or maculoconfluent rash occurs in at least 50 percent of patients on the face, thorax, and flexor surfaces, with islands of skin sparing. This has been described as "islands of white in a sea of red."
- Fever typically lasts for five to seven days, and may have a second one or-two day febrile phase fever after the initial fever breaks.
- Gastrointestinal symptoms include nausea, vomiting, and diarrhea.
- Respiratory symptoms include cough, sore throat, and nasal congestion.

Dengue is a viral disease that is found worldwide in tropical and subtropical environments, especially in urban and suburban areas, where the Aedes aegypti (and sometimes Aedes albopictus) mosquitoes are found. There is no vaccine against the dengue virus. Soldiers deployed or stationed in an area where there is ongoing transmission of the virus must protect themselves and their families by wearing permethrin-treated uniforms/clothing, using insect repellents containing DEET, picaridin and IR3535, and following the Personal Protection Measures outlined in
Technical Guide 36 . Mosquitoes that spread dengue virus bite both indoors and outdoors, and mostly during the daytime; therefore, it is important to ensure protection from mosquitoes throughout the entire day.
