On January 22, 2026, a new case of measles was reported by the Orange County Health Care Agency, found from a guest who visited both Disneyland Park, Disney California Adventure Park, and a restaurant at a Disney hotel in Anaheim. This visitor was at Disneyland between the times of 8 a.m. to 4 p.m., and at the California Adventure from 3 p.m. to closing time. Orange County health officials have reported this to be the second case of measles, just one week after the first case.
On February 9, a fourth case of measles was confirmed by L.A. County Department of Public Health. The infected traveler flew from Singapore to Los Angeles International Airport on February 9th aboard the Singapore Airlines flight 38. The plane followed a 14-hour flight and landed at 7 p.m. according to the L.A. County Department of Public Health. Over the following days, the traveler visited a few San Gabriel Valley fast food restaurants and potentially exposed the disease to others.
Measles is a highly contagious disease that can be spread easily within communities and travelers. Measles spread when an infected person breathes, coughs, or sneezes; tiny airborne particles linger in the air and stay on surfaces for hours.
Orange County health officials warn visitors that after initially being exposed to measles, symptoms may develop 7 to 21 days later. Symptoms of measles include fever, cough, runny nose, and red eyes. Infected individuals may be contagious for up to four days before a rash appears. Within a couple days, a red blotchy rash appears, starting from the face and spreading throughout the body. Measles could also lead to serious complications such as pneumonia, brain swelling, and even death.
Health officials recommend that the best way to protect oneself from measles is to get vaccinated before exposure to measles even occurs. Measles are preventable if visitors get two doses of the measles, mumps and rubella (MMR) vaccine before travelling.
According to the U.S. Centers for Disease Control and Prevention, there were a total of 2,280 confirmed cases of measles reported in the U.S. last year, the highest annual total since 1991. As of February 12, 2026, there have been a total of 910 confirmed cases nationwide, including 15 cases from California.
