(Santa Ana, CA) – The OC Health Care Agency (HCA) received notification of a confirmed case of measles who visited Orange County (OC). While infectious, this individual visited the following OC locations:
Thursday, 1/22/26
Disneyland Park, 8 a.m. to 4 p.m.
Disney California Adventure Park, 3 p.m. to closing
People who were at these locations during the date and times listed above may be at risk of developing measles from 7 to 21 days after being exposed and are advised to follow these recommendations:
Check your immunity status: People who are not fully immunized against measles or are unsure of their immunity status, should contact a health care provider about receiving the Measles, Mumps, and Rubella (MMR) vaccine.
If exposure occurred less than 7 days ago: Talk to your health care provider about vaccination or immune globulin for prevention. Immunoglobulin is recommended for certain individuals, such as infants under 12 months, pregnant people without immunity, or those with weakened immune systems.
If exposure occurred more than 7 days ago: Non-immune individuals should stay home and limit interactions with others for 21 days following exposure.
Monitor for symptoms: Watch 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.
If you suspect measles: Call your medical provider before visiting any health care facility to avoid exposing others.
“The best way to protect yourself and others is to get vaccinated before exposure occurs,” said Dr. Anissa Davis, Deputy County Health Officer. “Because measles is highly contagious, it can spread quickly within communities, even among those who haven’t traveled. There are populations who cannot receive the measles vaccine – whether due to age, health conditions or allergies. Those individuals may face significantly higher health risks when exposed to the virus.”
Measles is preventable with two doses of the MMR vaccine. People who are fully vaccinated are considered protected. Adults born before 1957 or who had measles in the past are generally immune.
Measles is a highly contagious viral illness that spreads through the air when an infected person breathes, coughs, or sneezes, and it can also spread through direct contact with infectious droplets. Symptoms typically include fever, cough, runny nose, and red eyes, followed by a rash that begins on the face and spreads to the body. Individuals who have unknown immunization status, or who have not received the measles vaccines, are at high risk of developing measles 7-21 days after being exposed.
Routine Measles Immunization Recommendations:
First MMR dose: 12–15 months of age
Second MMR dose: 4–6 years of age
Infants 6–11 months traveling internationally or to areas with a known outbreak should receive an early dose
Vaccinating children, adolescents, and adults helps protect infants too young for vaccination
The West Coast Health Alliance (WCHA) and recognized national medical associations continue to strongly recommend vaccines to protect children. Learn more here: WCHA Statement on Vaccines.

(Santa Ana, CA) – The OC Health Care Agency (HCA) received confirmation today of a measles case in a toddler. At this time, there is no evidence of public exposure linked to this case. Health officials report that there was no travel prior to infection.
“Measles is highly contagious. The risk is particularly high for any exposed individuals who are not immunized against measles, especially as cases continue to occur across the country and worldwide,” said Dr. Anissa Davis, Deputy County Health Officer. “Vaccination is the best protection.”
According to the Centers for Disease Control and Prevention (CDC), there have already been 588 confirmed measles cases in the United States in 2026, just one month into the year. By comparison, 2025 saw 2,267 cases, the highest annual total in more than 30 years.
Common symptoms include fever, cough, red watery eyes, and a rash that typically begins on the head before spreading to the rest of the body. Measles is the most contagious disease known, and it spreads very easily through the air and by direct contact with an infected person. People are contagious from approximately four days before the rash begins through four days after the rash appears.
Anyone who suspects they may have measles should call their medical provider before arriving at the medical office to avoid exposing others. Clinicians should immediately report any suspected measles cases to the OC Health Care Agency for guidance and testing coordination.
Vaccination remains the most effective way to prevent measles. About measles immunization:
Over 800 million doses of the MMR (Measles, Mumps, and Rubella) vaccine have been administered worldwide. Decades of research and real-world experience show that the vaccine is highly effective at preventing serious illnesses like measles, mumps, and rubella.
While no medical intervention is completely without risk, most side effects from the MMR vaccine are mild - like a sore arm or low fever. Serious reactions are rare, and the vaccine’s protection against dangerous diseases far outweighs the risks.
Public health agencies around the world, including the CDC and World Health Organization (WHO), continue to monitor vaccine safety closely.
The CDC’s Advisory Committee for Immunization Practices and the California Department of Public Health (CDPH) recommend MMR vaccination to protect against measles, mumps, and rubella.
Immunizing household members, including children, adolescents, and adults, is the best way to protect infants who are too young to receive the MMR vaccine.
Infants should receive their first MMR vaccine at 12-15 months of age. The second dose of MMR is given between 4 and 6 years of age, before starting school.
Measles is found in many parts of the world, including Europe, Asia, Africa, and the Middle East.
Children 6 to 12 months of age who are traveling internationally are recommended to receive a dose of the MMR vaccine prior to travel, to decrease their risk of infection.
Children 12 months and older, as well as adults, should receive two doses, at least 28 days apart, before travel if not already vaccinated.
A case of measles has been confirmed in an Orange County resident, an unvaccinated young adult, who had recently traveled internationally. They were not infectious while they travelled. The Health Care Agency’s Communicable Disease Control Division (CDCD) is reaching out to identified contacts.
The person was infectious while they visited the following location(s):
EOS Fitness Gym (27702 Antonio Pkwy, Ladera Ranch, CA 92694) on January 23rd between 2:00 and 4:00 PM
AFC Urgent Care Ladera Ranch (27522 Antonio Pkwy SUITE P3, Ladera Ranch, CA 92694) on January 23rd between 4:00 and 6:30 PM and again on January 26th 5:00 and 7:30pm
Measles is an acute viral illness typically presenting with fever, cough, coryza, and conjunctivitis, followed 3-5 days later by a rash. The maculopapular rash typically begins on the face and spreads down the torso and out to the extremities. The incubation period for measles ranges from 7-21 days after exposure and individuals are infectious from 4 days prior to rash onset until 4 days after rash onset. Measles is highly contagious and spreads via airborne transmission.
Individuals can be presumed to be immune to measles if they were:
born prior to 1957, OR
have received two doses of measles containing vaccine, OR
(Santa Ana, CA) — The OC Health Care Agency (HCA) has confirmed a case of measles in a young adult who recently travelled internationally. The HCA is notifying individuals who were exposed to the person in healthcare settings. Potential community exposure locations during their infectious period include the following:
EoS Gym (Ladera Ranch, 1/23/2026) between 2:00-4:00pm
AFC Urgent Care (Ladera Ranch, 1/23/2026 3:30-6:00pm & 1/26/2026 5-7:30pm)
According to the Centers for Disease Control and Prevention (CDC), there have been 416 confirmed cases of measles in the United States so far in 2026, and 2,255 cases in 2025, the highest annual case count in more than 30 years.
“Measles is highly contagious. Anyone planning domestic or international travel—or hosting visitors—should be fully vaccinated at least two weeks beforehand. Adults and others who are not immune remain at risk, especially as outbreaks continue across the country and worldwide,” said Dr. Anissa Davis, Deputy County Health Officer. “Vaccination is the best protection.”
Common symptoms include fever, cough, red watery eyes, and a rash that typically begins on the head before spreading to the rest of the body.

The California Department of Public Health (CDPH), in coordination with its partners in the West Coast Health Alliance (WCHA), endorses the 2026 American Academy of Pediatrics (AAP) Recommended Child and Adolescent Immunization Schedule. This schedule differs from recent national changes issued by the U.S. Centers for Disease Control (CDC).
The 2026 American Academy of Pediatrics (AAP) Immunization recommendations are similar to previous recommendations issued by AAP, adopted by CDPH, and endorsed by the West Coast Health Alliance. CDPH will continue to adopt the most recent AAP immunization recommendations for California pursuant to Health and Safety Code section 120164. This updated 2026 AAP Recommended Child and Adolescent Immunization Schedule will be posted on the CDPH immunizations recommendations website.
“The United States achieved elimination status for measles in 2000 with high vaccination rates. Now, we're seeing the highest numbers of measles cases, outbreaks, hospitalizations and deaths than we’ve seen in more than 30 years, driven by populations with low vaccination rates.” said Dr. Erica Pan, CDPH Director and State Public Health Officer. “We are at risk of losing our measles elimination status, and we all need to work together to share the medical evidence, benefits, and safety of vaccines to provide families the information they need to protect children and our communities."
CDPH has also issued separate recommendations for mpox vaccine to increase access for that vaccine to adolescents at increased risk of infection. Because the 2026 AAP recommendations are essentially unchanged from prior CDPH recommendations, health insurance coverage in California will continue to cover these recommended vaccines. If parents have questions about the effectiveness and safety of vaccines, they should discuss with their healthcare provider.
