Orange County officials have confirmed a second measles case tied to a Disneyland visitor in January 2026. The infectious individual attended both Disneyland Park and Disney California Adventure Park, raising concern for anyone present during those hours. Measles is highly contagious but preventable through vaccination, and early detection and immunization remain crucial to limiting exposure and protecting at-risk populations.

When and Where Did the Exposure Occur?

The exposure took place on January 22, 2026. The visitor was at Disneyland Park from 8 a.m. to 4 p.m. and at Disney California Adventure Park from 3 p.m. until closing. Anyone present at these locations during these times may be at risk of developing measles within 7 to 21 days after exposure.

How Can People Protect Themselves After Potential Exposure?

Health authorities recommend checking your immunity status with a healthcare provider. Those exposed within the past seven days may be advised to receive the MMR vaccine or immune globulin. High-risk groups include infants under 12 months, pregnant individuals without immunity, and people with weakened immune systems. Early consultation with a medical professional is essential.

What Are the Symptoms of Measles to Watch For?

Symptoms typically appear 7 to 21 days after exposure. They include fever, cough, runny nose, red eyes, and a rash that starts on the face and spreads to the body. Anyone experiencing these signs should contact their healthcare provider immediately to prevent further transmission.

Why Is Vaccination So Important?

Measles is a highly contagious viral illness that spreads through respiratory droplets and direct contact with infectious fluids. Two doses of the MMR vaccine provide effective protection. Vaccination not only protects individuals but also safeguards vulnerable populations who cannot receive the vaccine due to age, health conditions, or allergies.
