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

The Centers for Disease Control and Prevention (CDC) has updated its travel advisory in light of a worrying uptick in measles cases. With 1,088 confirmed cases of measles in the United States in 2025, the CDC strongly recommends that international travelers ensure they are vaccinated against the disease before venturing abroad.

"Measles is an ongoing risk around the world, and more international travelers are getting infected," the CDC advisory notes. Travelers can contract measles in numerous settings, including airports, train stations, and other high-traffic areas. To mitigate this risk, the CDC advises that all travelers to and from international destinations should be fully vaccinated against measles. Those who are not yet vaccinated or cannot be vaccinated are urged to consult a healthcare professional and potentially delay their travel plans.

One notable hub of concern is Denver International Airport, where several recent measles cases have been reported. According to the Colorado Department of Public Health and Environment, at least four passengers on a Turkish Airlines flight were confirmed to have contracted measles. Public health officials are working to alert the public about the potential areas of exposure linked to these cases.

The spread of measles, which occurs through coughing and sneezing and can linger in the air for up to two hours, remains a significant public health challenge. CDC data indicates that 96 percent of the recent measles cases involve individuals who were either unvaccinated or had an unknown vaccination status, although only 12 percent have required hospitalization.

Given the increased risk, the CDC's advisory, last reviewed on May 28, highlights the need for heightened vigilance among international travelers. With 62 cases in 2025 linked to international travel, ensuring proper vaccination could be key in curbing the transmission of this highly contagious virus. As the CDC continues to monitor the situation, it remains crucial for travelers to take proactive measures to protect their health and the health of others.
