4Avoid getting mosquito bites:
Use insect repellent on uncovered skin surfaces when outdoors, especially during the day. When using sunscreen, apply it before insect repellent.
Repellents containing 30% to 50% DEET (N,N-diethyl-m-toluamide) are recommended for adults and children over 2 months of age and effective for several hours. Repellents with lower amounts of DEET offer shorter-term protection and must be applied more often.
Repellents containing up to 15% picaridin, which must be applied often, are available in the US. Repellents with higher concentrations of picaridin may be available in some regions outside the US.
Protect infants less than 2 months of age by using a carrier draped with mosquito netting with an elastic edge for a tight fit.
Wear loose, long-sleeved shirts and long pants when outdoors.
Clothing may also be sprayed with repellent containing permethrin or another EPA-registered repellent for greater protection. (Remember: don't use permethrin on skin.)
If traveling in dengue infested areas, stay in hotels or resorts that are well screened or air conditioned and take measures to reduce the mosquito population.
