A second measles case has been confirmed in Orange County this week, with health officials warning that visitors to Disneyland Resort on January 28, 2026 may have been exposed to the highly contagious virus. The infected individual, an international traveler who arrived through Los Angeles International Airport, spent several hours at both theme parks and a popular character dining restaurant before their diagnosis, creating multiple potential exposure points for other guests.
The OC Health Care Agency issued a public health alert Saturday after receiving notification from state and Los Angeles County health departments about the case. Officials have identified specific timeframes when other visitors may have been at risk, including a morning visit to Goofy's Kitchen at the Disneyland Hotel and an afternoon and evening spent in both Disneyland Park and Disney California Adventure. The extended exposure windows mean potentially hundreds or even thousands of guests could have been in proximity to the infected traveler during their visit.
This marks Orange County's second confirmed measles case in less than a week, with the first case announced Wednesday involving another international traveler. The back-to-back cases highlight ongoing concerns about measles importation into California communities, particularly given the virus's extraordinary contagiousness and ability to spread through airborne transmission. Public health experts note that measles can remain infectious in the air for up to two hours after an infected person leaves a location, making crowded venues like theme parks especially vulnerable to transmission events.
The situation has prompted coordinated response efforts across multiple health jurisdictions and organizations. County health officials are working directly with Disneyland management to notify potentially exposed employees, while also coordinating with Los Angeles County authorities and airport officials to track the infected individual's movements and identify anyone else who may have been exposed during their travel through Southern California.
Where and When Exposure Occurred
Health officials have released detailed information about the specific locations and times when Disneyland Resort visitors may have encountered the infected traveler on Wednesday, January 28. The first identified exposure site is Goofy's Kitchen, the character dining experience located within the Disneyland Hotel, where potential exposure occurred between 10:30 a.m. and 1:30 p.m. This three-hour window encompasses a typical meal service period when multiple families would have been dining in the same enclosed restaurant space.
Following the Goofy's Kitchen visit, the infected individual entered the theme parks, creating a second exposure window from 12:30 p.m. until park closing at both Disneyland Park and Disney California Adventure. This timeframe represents the majority of a typical park day and means the traveler potentially moved through numerous attractions, dining locations, retail shops, and crowded walkways while infectious.
The extended nature of the park exposure window significantly complicates contact tracing efforts, as the infected person could have been anywhere within the two parks over several hours. Unlike the confined restaurant setting at Goofy's Kitchen, the theme park exposure involves both indoor and outdoor spaces across hundreds of acres, making it impossible to pinpoint exactly which specific attractions or areas posed the highest risk.
Anyone present at either identified location during the specified times on January 28 should consider themselves potentially exposed to measles and follow the health department's recommended precautions.
Recommended Actions for Potentially Exposed Individuals
The OC Health Care Agency has outlined specific steps that potentially exposed individuals should take to protect themselves and prevent further spread of the disease. The first priority is verifying immunity status through consultation with a healthcare provider about MMR vaccination history. Many adults received childhood vaccines but may not have documentation readily available, making it necessary to review medical records or undergo antibody testing to confirm protection.
Timing matters significantly in post-exposure prevention. People whose exposure occurred within the past seven days should contact their healthcare provider immediately about receiving either the MMR vaccine or immune globulin as preventive measures. Immune globulin is particularly important for high-risk populations who cannot receive the standard vaccine, including infants younger than 12 months, pregnant individuals without documented immunity, and people with compromised immune systems due to medical conditions or treatments.
Health officials emphasize the importance of symptom monitoring during the incubation period. All potentially exposed individuals should watch for fever or unexplained rash developing between seven and 21 days after the January 28 exposure date. These symptoms represent the hallmark signs of measles infection and require immediate medical evaluation.
However, anyone who develops symptoms consistent with measles should call their healthcare provider before visiting a medical facility. This critical step prevents further disease transmission in waiting rooms, examination areas, and other healthcare settings where vulnerable patients may be present. Healthcare providers can arrange for isolated evaluation procedures that minimize exposure risk to other patients and staff.
How Measles Spreads and Manifests
Measles ranks among the most contagious infectious diseases, spreading primarily through airborne transmission when infected individuals breathe, cough, or sneeze. The virus particles can remain suspended in air for extended periods, meaning people can become infected simply by entering a space where an infectious person was present hours earlier. Direct contact with infectious droplets on surfaces provides another transmission route, though airborne spread represents the primary concern.
The disease typically begins with nonspecific symptoms including fever, cough, runny nose, and red watery eyes. These initial signs emerge before the characteristic measles rash appears, creating a window when infected individuals are contagious but may not yet realize they have measles. Many people in this early stage might attribute their symptoms to a common cold or seasonal allergies, potentially continuing their normal activities and unknowingly exposing others.
The distinctive measles rash typically appears three to five days after initial symptoms begin, starting on the face before spreading downward across the rest of the body. The rash consists of flat red spots that may merge together as they spread, eventually covering large areas of skin.
Unvaccinated individuals face particularly high risk after exposure, with the disease typically manifesting seven to 21 days after contact with the virus. The MMR vaccine provides effective protection when administered in the recommended two-dose series. Public health authorities consider fully vaccinated individuals protected from measles infection even after known exposure events.
Context of Orange County Cases
This latest case follows Wednesday's announcement of Orange County's first measles infection of 2026, also involving a young adult with recent international travel history. The appearance of two imported measles cases within days of each other reflects broader patterns of disease movement across international borders and into communities with variable vaccination coverage.
Dr. Anissa Davis, Orange County's Deputy Health Officer, emphasized that measles risk extends beyond international travelers themselves. “Measles doesn't only affect people who travel internationally, everyone is at risk if they're not protected,” Davis stated in the health agency's announcement. “Because measles is highly contagious, it can spread quickly within communities, even among those who haven't traveled. The best way to protect yourself and your loved ones is to get vaccinated before exposure occurs.”
The statement reflects public health concern that imported measles cases can trigger secondary transmission chains within local communities, particularly in areas where vaccination rates have declined or where pockets of unvaccinated individuals exist. Unlike diseases requiring prolonged close contact for transmission, measles can spread through casual proximity in public spaces, making comprehensive vaccination coverage essential for preventing community outbreaks.
Ongoing Response Efforts
The HCA Communicable Disease Control Division has initiated coordinated response efforts involving multiple agencies and organizations. Disneyland Resort management is working closely with health officials to identify and notify employees who worked at the identified exposure locations during the relevant timeframes on January 28. Theme park cast members interact with thousands of guests daily across multiple locations, making their potential exposure a significant concern for ongoing transmission risk.
Coordination extends beyond Orange County's boundaries through partnerships with Los Angeles County health authorities and officials at LAX, where the infected traveler first entered California. This multi-jurisdictional approach recognizes that the individual's movement through Southern California created potential exposure points across multiple communities and public spaces.
The coordinated response aims to identify all potential exposures, notify at-risk individuals, and prevent secondary transmission that could lead to broader community spread. Health officials continue monitoring for additional cases that might emerge during the 21-day incubation period following the Disneyland exposures.
Were you at Disneyland on January 28? Check your vaccination records now and keep an eye out for any symptoms over the next couple weeks. Pass this along to anyone who might have been there that day, especially if they've got young kids or family members who can't get vaccinated.
