An infected mosquito passes the virus to you through a bite on your skin. The virus enters the bloodstream and spreads throughout the body.

Your risk may be higher if you travel to:
- Southeast Asia and China
- Middle East
- The Caribbean
- Central and South America
- Areas in central and south Pacific
- Parts of Florida and Texas
Children and infants may have not have symptoms or may have flu-like symptoms. Adults may develop a more serious, life-threatening illness. The main symptoms are high fever and at least 2 from the list below:
- Eye pain
- Chills and fever
- Muscle or bone pain
- Red or purple spots in skin
- Minor bleeding in the nose or gums
- Easy bruising
- Nausea or vomiting
The fever goes away within 3-7 days after symptoms start. This is when the warning signs of a serious infection may appear. These may include:
- Severe belly pain
- Frequent vomiting
- Bleeding from the gums or nose that's hard to stop
- Black tarry stools or blood in the urine
- Difficulty breathing
- Pale, cold, or clammy skin
A serious infection can lead to shock and organ failure.
Your doctor will ask about your symptoms, and health and travel history. You will also have:
- A physical exam
- Blood tests
The goal of care is to ease symptoms while the body fights the virus. Care includes:
- Replacing fluids
- Acetaminophen for pain and fever
Talk to your doctor about the medicines you take. You should taking avoid aspirin and similar medicines because it may cause bleeding.
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.
