The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Advisory to notify healthcare providers, public health authorities and the public of an increased risk of dengue virus (DENV) infections in the United States in 2024. In the United States, Puerto Rico has declared a public health emergency (1,498 cases) and a higher-than-expected number of dengue cases have been identified among U.S. travelers (745 cases) from January 1 – June 24, 2024.

Recommendations for the Public

• Learn how to prevent mosquito bites.

o Use Environmental Protection Agency-approved repellents during travel to and after returning from areas with frequent or continuous dengue transmission.

o Wear loose-fitting, long-sleeved pants and shirts.

• Control mosquitos at home indoors and outdoors.

o Use air conditioning and window screens, when possible, to lower risk for mosquito bites indoors.

o Dump and drain containers that hold water to reduce mosquito egg-laying sites in your home and neighborhood.

• Seek medical care if you have a fever or have dengue symptoms and live in or traveled

to an area with dengue outbreaks.

• If you plan international travel to an area with frequent or continuous dengue

transmission, protect yourself from mosquito bites during and after your trip.
