Most cases of dengue in the U.S. occur in people who contracted the disease elsewhere, the CDC says, while also noting that local transmission is common in American Samoa, Puerto Rico, and the U.S. Virgin Islands. There have been 496 cases of dengue reported in the U.S. so far this year, according to the most recent, data.
About 25% of those who are bitten by an infected mosquito will get sick — and cases can range from mild to severe. Per the CDC, symptoms include fever, nausea, vomiting, rash, and body pains in the muscles and, joints hence the name “breakbone fever.” Treatment includes acetaminophen, rest and fluids.

Those who have had dengue before are more likely to develop a severe case, which the CDC said “can be life-threatening within a few hours.” Symptoms include belly pain, frequent vomiting or internal bleeding.
Anyone who suspects they have severe dengue should “see a healthcare provider or go to the emergency room immediately.” The organization added, “Severe dengue is a medical emergency. It requires immediate medical care.”
