Visit a travel clinic or your healthcare provider for pre-travel medical care.
Pack acetaminophen (also known as paracetamol outside of the United States) in your first aid kit. These medications can be used to manage fever and body pain in case you get dengue.
Use a bed net if air conditioned or screened rooms are not available or if sleeping outdoors.
Even if you do not feel sick, travelers returning from an area with risk of dengue should take steps to prevent mosquito bites for 3 weeks so they do not spread dengue to mosquitoes that could spread the virus to other people.
Symptoms of dengue usually begin within 2 weeks after being bitten by an infected mosquito.
See a healthcare provider if you develop a fever or have symptoms of dengue. Tell him or her about your travel.
