Tips on Preventing Mosquito and Other Insect Bites
Many diseases, like malaria and dengue, are spread through insect bites. One of the best protections is to prevent insect bites by:
Using insect repellent (bug spray) with 30%-50% DEET. Picaridin, available in 7% and 15% concentrations, needs more frequent application
There is less information available on how effective picaridin is at protecting against all of the types of mosquitoes that transmit malaria.
Wearing long-sleeved shirts, long pants, and a hat outdoors.
Remaining indoors in a screened or air-conditioned area during the peak biting period for malaria (dusk and dawn).
Sleeping in beds covered by nets treated with permethrin, if not sleeping in an air-conditioned or well-screened room.
Spraying rooms with products effective against flying insects, such as those containing pyrethroid.
Avoiding Other Injuries and Illness
Car crashes are a leading cause of injury among travelers. Protect yourself from these injuries by:
Not drinking and driving.
Wearing your seat belt and using car seats or booster seats in the backseat for children.
Following local traffic laws.
Wearing helmets when you ride bikes, motorcycles, and motor bikes.
Not getting on an overloaded bus or mini-bus.
Hiring a local driver, when possible.
