San Mateo County Health has issued an urgent public health alert following a confirmed measles case, advising residents about potential exposure at a popular Burlingame restaurant. This crucial notice serves to inform the community, particularly those who visited Panda Express on Burlingame Avenue on specific dates in February 2026, about monitoring for symptoms and taking immediate preventative steps. Prompt action and public awareness are vital in safeguarding our community against this highly contagious viral infection. San Mateo County Health is working diligently with Santa Clara County Public Health officials to manage the situation and ensure public safety.
Understanding the Recent Measles Exposure in Burlingame
A confirmed case of measles has been identified in an adult individual who recently returned from international travel. This person, a Santa Clara County resident, was vaccinated against measles and is currently isolating at home to prevent further transmission. Despite being vaccinated, the individual could still transmit the virus, underscoring the importance of public vigilance.
The potential exposure site is the Panda Express located at 1453 Burlingame Avenue in Burlingame, California. Individuals who were present at this restaurant on February 23 or February 24, 2026, between 11:30 a.m. and 1:30 p.m., may have been exposed to the measles virus.
Who is Most at Risk?
While the risk for fully vaccinated individuals remains low, certain groups are particularly vulnerable if exposed to measles. These include:
Unvaccinated individuals: Those who have not received the measles, mumps, and rubella (MMR) vaccine face the highest risk of contracting the disease if exposed.
Pregnant individuals: Measles infection during pregnancy can lead to serious complications for both the mother and the baby, including miscarriage, premature birth, and low birth weight.
Immunocompromised individuals: People with weakened immune systems due to illness or medication are at a greater risk of severe disease and complications.
If you fall into any of these categories and were at the specified location during the exposure times, it is especially important to monitor your health closely and contact your healthcare provider for guidance.
What is Measles? A Critical Overview of the Disease
Measles is an extremely contagious respiratory disease caused by a virus. It spreads through the air when an infected person coughs or sneezes. The measles virus can remain active and contagious in the air or on surfaces for up to two hours after an infected person leaves the area. This explains why exposure in a public setting like a restaurant can be a serious concern.
Recognizing Measles Symptoms
Symptoms of measles typically appear 7 to 14 days after exposure, though they can manifest up to 21 days later. It’s crucial to be aware of the signs:
High fever: Often the first symptom, temperatures can reach 104°F (40°C) or higher.
Cough: A persistent dry cough is common.
Runny nose: Similar to a common cold.
Red, watery eyes (conjunctivitis): The eyes may also be sensitive to light.
Koplik spots: Tiny white spots with bluish-white centers on a red background, found inside the mouth on the inner lining of the cheek, typically appear 2-3 days after symptoms begin.
Rash: A characteristic red, blotchy rash usually appears 3-5 days after the first symptoms. It often starts on the face and behind the ears, then spreads down the neck, torso, arms, and legs. The rash can last for 5-6 days.
Individuals who remain symptom-free for more than 21 days after their last potential exposure are generally no longer considered at risk of developing measles from that specific exposure incident.
Immediate Steps: What to Do if You Suspect Exposure
If you were at the Panda Express in Burlingame on February 23 or 24, 2026, between 11:30 a.m. and 1:30 p.m., it’s important to take proactive measures.
Monitoring Your Health
Watch for symptoms: Carefully monitor yourself and anyone you were with for the symptoms described above for 21 days from the date of your potential exposure.
Stay home if symptomatic: Should you develop any measles-like symptoms, it is absolutely critical to stay home to prevent further spread of the virus. Do not go to work, school, or public places.
Contact your healthcare provider IMMEDIATELY: Before seeking in-person medical care, call your health care provider right away. Explain your potential exposure and symptoms. This allows them to prepare for your arrival, implement infection control measures, and ensure you receive care without putting others at risk in waiting rooms or clinics.
The Power of Prevention: Measles, Mumps, and Rubella (MMR) Vaccine
The most effective way to protect against measles is through vaccination. The measles, mumps, and rubella (MMR) vaccine is highly effective and safe, providing robust protection against all three diseases. For most people, two doses of the MMR vaccine offer nearly 97% protection against measles.
Importance of Vaccination
Individual Protection: Vaccination significantly reduces your risk of contracting measles and experiencing its potentially severe complications, which can include pneumonia, brain swelling (encephalitis), and even death.
Community Protection (Herd Immunity): When a high percentage of the population is vaccinated, it creates “herd immunity,” protecting those who cannot be vaccinated, such as infants, pregnant women, and immunocompromised individuals.
Accessibility: San Mateo and Santa Clara counties continue to follow existing state vaccination guidelines. The MMR vaccine and other recommended vaccines are covered by health insurance for almost everyone in California, making this vital protection readily accessible.
In 2026, San Mateo County has reported two confirmed cases of measles, following one case in 2025. These numbers underscore the persistent threat of measles, especially with international travel. Adherence to vaccination schedules helps communities live long, healthy lives, free from the burden of preventable diseases.
