Measles Resurgence: What Travelers Need to Know This Summer

As the United States faces a significant measles outbreak, experts urge travelers to ensure vaccination and consider safety measures in crowded places this summer.

Measles is making headlines once again as an outbreak grips the United States, particularly in Texas, where the Centers for Disease Control and Prevention (CDC) has confirmed over a thousand cases in 2025. This alarming trend has been exacerbated by the onset of summer travel, prompting concerns about the highly contagious virus spreading among vacationers. In addition to the rise in infections, the outbreak has tragically resulted in at least three fatalities.

Travelers need to be vigilant, especially in crowded environments commonly associated with summer trips. Historical data highlights the contagiousness of measles, with a well-documented outbreak stemming from a 2014 Disneyland visit that saw cases leap beyond a hundred. Fortunately, an effective vaccine is available, and ensuring that all family members are vaccinated before embarking on any journey is crucial for safety.

Airports, airplanes, and populated venues can facilitate the virus’s transmission, as it remains airborne and can linger long after an infected individual has left. Even after exposure, individuals experience symptoms before developing the noticeable rash, particularly when they have a runny nose—an early sign that coincides with the presence of the virus in bodily fluids.

For those at risk, including the unvaccinated or immunocompromised, wearing masks in crowded areas is advisable, as it helps mitigate not just measles but other potential infections. Moreover, careful planning for avoiding populous indoor settings can further enhance personal safety during this vulnerable time.
