While most fans who caught “Avengers: Endgame” this past weekend walked out with a sense of joy after seeing a great movie, some fans in California may have walked out with something else – Measles.

Well, not exactly but theatergoers in Orange Country, California may have been exposed to the disease thanks to a 20-something from Placentia who was recently diagnosed with Measles, who caught the flick at the AMC Movie Theater in Fullerton somewhere between 11 pm April 25th and 4 am April 26th.

Officials at the Orange County Health Care Agency say the woman, who is now “under voluntary isolation at home,” recently traveled to “one of many countries currently experiencing widespread measles activity.” Source: Atlanta News Now
