Measles infections are climbing in the U.S., and California counties are urging residents to get vaccinated.<\/p>\n
Orange County has confirmed two cases of measles in the past week, one involving an international traveler. The infected individual arrived at Los Angeles International Airport (LAX) and visited Disneyland last month.<\/p>\n
The Orange County Health Care Agency (HCA) said in a news release<\/a> that the patient traveled to Orange County on Jan. 28. The individual visited Goofy\u2019s Kitchen at the Disneyland Hotel and spent the day at Disneyland Park and Disney California Adventure Park. The agency stated, \u201cPeople who were at these locations during the date and time listed above may be at risk of developing measles from 7 to 21 days after being exposed.\u201d<\/p>\n The agency advised those who may have been exposed at these locations to check their immunity status and talk to their health care provider about vaccination. The statement added, \u201cWatch for fever and\/or an unexplained rash from 7 to 21 days after exposure. If symptoms develop, call your health care provider immediately for guidance.\u201d<\/p>\n Another recent case in Orange County involved an unvaccinated toddler with no travel history outside the area. Dr. Anissa Davis, deputy county health officer at the HCA, emphasized that everyone is at risk, even if they have not traveled. \u201cBecause measles is highly contagious, it can spread quickly within communities, even among those who haven\u2019t traveled. The best way to protect yourself and your loved ones is to get vaccinated before exposure occurs.\u201d<\/p>\n Continue Reading Article After Our Video<\/p>\n Recommended Fodor\u2019s Video<\/p>\n Meanwhile, Los Angeles County has reported three measles cases<\/a> in the last week, all related to travel.

County residents begin to travel this summer and with measles cases increasing among those who have recently traveled, we remind everyone that the best way to protect yourself and your family from infection is with the highly effective measles vaccine.\u201d<\/p>\n Disneyland Park welcomes about 65,000 visitors daily<\/a>, with a capacity of up to 85,000. Disney California Adventure Park can host as many as 27,000 guests.<\/p>\n Measles Is Back<\/p>\n Measles was declared eliminated in the U.S. in 2000 but has resurged in recent years alongside declining immunization rates. By Jan. 29, 2026, the U.S. had confirmed 588 measles cases<\/a>; 2025 was the worst year since 2000, with 2,267 cases and three deaths.<\/p>\n Measles is highly contagious, but serious illness or death is preventable. Children can receive two doses of the MMR<\/a> (measles, mumps, and rubella) vaccine or the MMRV (measles, mumps, rubella, and varicella) vaccine. The MMR vaccine is 97% effective against measles when both doses have been given, and there is no evidence linking the vaccine to autism. The CDC notes, \u201cAlmost everyone who has not had the MMR vaccine will get sick if they are exposed to those viruses.\u201d<\/p>\n
