The CDC has issued a global travel alert for dengue, noting that travelers returning to the U.S. have tested positive for the mosquito-borne illness. This alert, classified as a “Level 1” notice, encourages travelers to practice basic precautions.
Key Points:
- Dengue Overview: Also known as “breakbone fever,” dengue is transmitted through infected mosquito bites. Symptoms can include fever, headache, muscle pain, and in severe cases, can lead to hemorrhaging and organ failure.
- Severity: While many infected individuals may experience mild symptoms or none at all, severe cases can be life-threatening, especially for children and those with underlying health conditions.
- Current Risk: Dengue poses a continuous risk in several countries. The CDC has identified regions with elevated risk including Afghanistan, Bolivia, Colombia, Cuba, and Vietnam, among others.
- Cases in the U.S.: Over 525 dengue cases have been reported in the U.S. in 2026.
Prevention Tips:
- Use insect repellent.
- Wear long sleeves and pants.
- Stay in air-conditioned or screened-in accommodations.
Travel Guidance:
The CDC’s advisory does not recommend canceling travel plans but serves as a reminder for travelers to remain vigilant, especially in tropical and subtropical areas where outbreaks are common.
