Dengue fever cases rise in spring break locations like Mexico, Puerto Rico: CDC

As the spring break season kicks off and travelers head south for warmer weather, there is a growing concern about the increased risk of mosquito-borne diseases, particularly dengue fever. The Centers for Disease Control and Prevention (CDC) has reported a rise in global cases of dengue fever, with a particular warning for U.S. travelers.

In a Health Alert Network advisory released on March 18, the CDC highlighted that dengue activity and transmission remain high in some parts of the U.S. and globally, including Puerto Rico and the U.S. Virgin Islands. As spring and summer travel coincide with the peak season for dengue in many countries, the CDC has issued a level 1 health alert, urging the public to take necessary precautions.

To prevent mosquito bites and reduce the risk of contracting dengue fever, the CDC recommends using EPA-registered insect repellent, wearing long-sleeved shirts and pants outdoors, and sleeping in air-conditioned rooms or those with screened windows. Many countries have reported a higher-than-usual number of dengue cases in recent years, including popular travel destinations like Brazil, Colombia, Mexico, and the Philippines.

Dengue fever is a virus transmitted through mosquito bites and is common in regions such as the Americas, Africa, Asia, and the Pacific Islands. Symptoms of dengue fever include body aches, nausea, vomiting, and rash, typically appearing within two weeks of being bitten. While most cases of dengue fever are mild and resolve within a week, severe cases can lead to complications such as headaches, joint pain, and even death.

There is currently no specific medication to treat dengue fever, and infected individuals are advised to rest, stay hydrated, and manage symptoms with pain relievers like acetaminophen. A vaccine is available for children between 9 and 16 years old who have previously tested positive for dengue and live in high-risk areas.

As travelers embark on spring break adventures, it is essential to be aware of the potential health risks posed by mosquito-borne diseases like dengue fever. By following CDC guidelines, using insect repellent, and taking necessary precautions, travelers can enjoy a safe and healthy vacation experience.
