Currently, there is no vaccine available for prevention of dengue infections; however, research is ongoing and it is expected that an effective dengue vaccine will be available within five to ten years.
Visitors to endemic areas are advised to protect against the dengue virus vector – the Aedes aegypti mosquito. The Aedes aegypti mosquito is also the vector for yellow fever, so dengue and yellow fever infection prevention strategies are similar, although a yellow fever vaccine is available and immunization is recommended when traveling to endemic areas (Yellow fever prevention). Avoiding mosquito bites is the best way to reduce the risk of dengue virus infection. Aedes aegypti is a daytime biting mosquito that prefers humans. The most common exposure times are early morning and late afternoon and evening.
Avoiding mosquito bites:
- Wear clothes that cover the arms and legs.
- Wear light-colored clothing (mosquitos are attracted to dark colors).
- Do not wear scented products.
- Apply DEET-containing insect repellent to skin and clothing every 6 hours.
- Remain in well-screened or air-conditioned areas when possible.
- Use mosquito netting.
