Locations of potential measles exposure
You might be at risk of getting measles if both of these apply to you:
- You are not immune to measles OR you are unsure whether you were vaccinated.
- You visited the sites below at the dates and times indicated.
If both of these apply to you, you should do the following:
- Review your immunization records to learn if you are protected against measles. Visit myvaccinerecord.cdph.ca.gov or contact your healthcare provider.
- Call your healthcare provider immediately if you are pregnant, the parent of an infant, have a weakened immune system, or are unimmunized.
- Monitor for symptoms for seven to 21 days after the day of potential exposure.
Symptoms of measles include fever, cough, runny nose, conjunctivitis (red eyes), and a rash which usually appears 10 to 21 days after exposure. If you have symptoms, it is very important to call ahead to any medical facility before going in and tell them that you may have been exposed to measles, so that the facility can take measures to protect other patients and visitors.
| Date | Place | Time of possible exposure |
| May 21 | H Mart 1710 Oakland Rd., San Jose, CA 95131 | 7:15 to 9 p.m. |
| May 23 | Starbucks 35040 Newark Blvd., Newark, CA 94560 | 11:45 a.m. to 2 p.m. |
| May 25 | Trader Joe's 1306 Great Mall Pkwy., Milpitas, CA 95035 | 4:45 to 8 p.m. |
The Bay Area benefits from high rates of vaccination against measles. Most people in the area received two doses of measles vaccine (“MMR vaccine”) as children and are at low risk of getting measles if exposed. Two doses of MMR vaccine is the best protection against measles. The last case of measles in a Santa Clara County resident was in 2019.
