**CDC Updates Travel Advisory Amid Surge in Measles Cases**

The Centers for Disease Control and Prevention (CDC) has updated its travel advisory following a significant increase in measles cases. As part of the new guidance, the CDC is urging all international travelers to ensure they are vaccinated against the measles virus before embarking on their journeys.

According to the latest CDC data, there have been 1,088 confirmed measles cases in the United States in 2025, with 96 percent of these cases occurring in individuals who were either unvaccinated or had unknown vaccination status. Only 12 percent of confirmed cases have resulted in hospitalization. The CDC also noted that 62 of these measles cases have been linked to international travel.

“Measles is an ongoing risk around the world, and more international travelers are getting infected," the CDC advisory states. "Travelers can catch measles in many travel settings including travel hubs like airports and train stations, on public transportation like airplanes and trains, at tourist attractions, and at large, crowded events."

One area of concern is Denver International Airport, where health authorities have closely monitored measles occurrences. The Colorado Department of Public Health and Environment reported that at least four passengers on a recent Turkish Airlines flight contracted measles. These cases were identified among passengers who were at the airport around the same time on May 14.

In response to these developments, the CDC advises all international travelers to be fully vaccinated against measles. For those who are not vaccinated or cannot receive the vaccine, the CDC recommends consulting a medical professional and considering the potential risks before traveling.

The measles virus spreads through coughing and sneezing and can linger in the air for up to two hours, increasing the risk of transmission in crowded and enclosed spaces. The CDC reviewed its advisory most recently on May 28 to reflect the current state of the outbreak and to promote increased vaccination coverage among travelers.
