A total of 49 of the 211 students from the University of Texas at Austin who traveled to Cabo San Lucas, Mexico, for spring break have tested positive for the coronavirus, according to a statement from the university.
They went on the March 14-19 trip against the advice of White House officials who asked that people avoid gathering in groups of more than 10, and refrain from nonessential air travel.
Texas House Speaker Dennis Bonnen had a blunt message for the spring breakers.
"Quit being an a**," he told CNN affiliate KXAN. "Get over yourselves. Whether you think this is an issue or not, it is. Whether you think it could affect you or not, it does. The reality of it is, if I'm a college kid who's going to spring break in Mexico, you're affecting a lot of people. Grow up."
As some of the spring breakers took commercial flights home, public health officials said dozens of other passengers are being monitored.
The students who tested positive are in self-isolation, health officials said. The Department of State Health Services has been alerted.
