(Santa Ana, CA) – Summer travel is underway and the OC Health Care Agency (HCA) encourages residents from Orange County (OC) to be up to date on measles vaccinations, following a Health Alert from the Centers for Disease Control and Prevention (CDC). The CDC warns of an increase in measles cases, with 88% of the cases connected to international travel. You can read the CDC’s Health Alert here.

“Measles (rubeola) is extremely contagious,” said Dr. Regina Chinsio-Kwong, County Health Officer and Chief of Public Health Services. “One person infected by measles can infect 9 out of 10 of their unvaccinated close contacts. To prevent infection and spread, residents, especially those planning to travel overseas or who are welcoming visitors from overseas, should make sure they are up to date on their MMR (measles-mumps-rubella) vaccine,” she said.

Follow up with your primary care provider or local pharmacy for more information on where to get a measles vaccine. The HCA Travel Immunization Clinic offers vaccines by appointment. For more information on available vaccines click here.

The CDC has been notified of 16 confirmed U.S. cases of measles since the first of 2023, compared to 3 cases during the same time period in 2022. Most of the cases were among children who had not received the MMR vaccine. To prevent measles infection and spread from importation, all U.S. residents should be up to date on their MMR vaccinations, especially prior to international travel, regardless of the destination.
