Treatments
Prevention
If you travel to areas where dengue fever is common:
- Stay in places with screens or air conditioning.
- Cover your skin with long clothes, socks, and shoes.
- Use bug sprays that contain DEET.
- Use mosquito netting treated with bug spray.
- Keep in mind mosquitoes are more active during early morning, late afternoon, and early evening.
- Tip out standing water in buckets, flower pots, or other containers. Mosquitoes breed in standing water.
