(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.
