Dengue is most common in the tropics and subtropics, such as Southeast Asia, Central and South America, and the Caribbean

Dengue is caused by the dengue virus. This virus is present in most tropical and subtropical parts of the world. It's most common in Southeast Asia and the Caribbean. But a few people have gotten dengue in the southern United States and Hawaii.
When a mosquito bites an infected person, it picks up the virus and gives it to the next person it bites.
For 2 to 3 days, you'll feel weak and tired and have:
After you have these symptoms, you may feel better for a day, and then the fever and rash may come back, this time on your chest, back, arms, and face.
In more severe cases, people may feel weak for several weeks, but it's rare to die from dengue fever.
Dengue hemorrhagic fever is a much more severe type of dengue. It mainly affects children younger than 10 in areas where dengue is common.
If you have dengue hemorrhagic fever, you have dengue symptoms and also:
Bleeding from your nose, mouth, rectum, and any puncture wounds
Pain in your belly
Throwing up blood
Blood in your stool or in urine
Purple spots on your skin from bleeding under your skin
Very low blood pressure (shock)
Go to the hospital right away if you have symptoms of dengue hemorrhagic fever.
There's no medicine to kill the dengue virus. Doctors will:
Don’t take aspirin or ibuprofen because they can cause bleeding or make it worse.
Doctors will keep you under mosquito nets while you're sick so mosquitoes don't pick up the infection from you and spread it to other people.
