U.S. CDC: Ongoing Risk of Dengue Virus Infections and Updated Testing Recommendations in the United States
Please take a moment to review this U.S. CDC health advisory about an increased risk of dengue virus infections in the U.S. in connection with an ongoing global surge in dengue activity. The risk of locally-transmitted dengue in Maine remains very low. People in Maine are more likely to acquire dengue infection while traveling to locations with ongoing dengue activity. So far in 2025, Maine reported one confirmed dengue case in a returning traveler.
Health care providers should consider a dengue diagnosis in patients with unexplained febrile illness, particularly patients returning from areas with heightened dengue activity. Confirmed and suspected patients with dengue should be reported to the Maine CDC by electronic laboratory reporting.
