NYT Summer travel raises fears that the highly infectious virus will spread. Here’s how to protect yourself and your family. Measles, most unfortunately, is back in the news and in the air. In the United States, more than a thousand cases have been reported to the Centers for Disease Control and Prevention in 2025, the majority of them in an outbreak in Texas, which is still going on, and has resulted in at least three deaths.
Because measles is one of the most infectious viruses known, summer travel raises fears that it will spread, and that crowded conditions may place travelers at risk, either en route to or at their destinations. One of the most notorious outbreaks in the United States was, in fact, travel related: a 2014 exposure at Disneyland that resulted in well over 100 cases.
