Heads up, Bay Area residents! Public health officials are issuing an alert regarding potential Bay Area measles exposure after an individual infected with the virus visited several public locations across Santa Clara and Alameda counties earlier this month. This news serves as a crucial reminder that even diseases we consider largely controlled can re-emerge, especially amid concerns about falling vaccination rates nationally.
The infected individual, who had recently returned from international travel, is now recovering in isolation and fortunately did not require hospitalization. However, they were contagious during their visits, prompting health authorities to act swiftly.
Potential Exposure Locations and Times
It’s vital for anyone who was at the following locations during the specified times to be aware of potential Bay Area measles exposure:
- H Mart on 1710 Oakland Road in San Jose:
- Date: May 21
- Starbucks on 35040 Newark Blvd. in Newark (measles exposure Newark Starbucks):
- Date: May 23
- Trader Joe’s on 1306 Great Mall Parkway in Milpitas (measles exposure Milpitas Trader Joe’s):
- Date: May 25
Notices have been posted at these businesses to alert patrons. The exact times of the visits were detailed in a Thursday news release, so if you were at these locations on these dates, it’s highly recommended to check those specific times.
The Local and National Context
This isn’t an isolated incident. While the last confirmed measles case in a Santa Clara County resident was back in 2019, there have been other exposures involving nonresidents since then, including an international traveler earlier in 2024.
The new case arrives as several areas across the nation are contending with measles outbreaks. As of Thursday, the Centers for Disease Control and Prevention (CDC) reported over 1,000 confirmed measles cases in 33 states. Alarmingly, in 96% of those cases, the patients were unvaccinated or their vaccination status was unknown. The situation is serious enough that in Texas, a measles outbreak tragically resulted in the deaths of two children.
As of May 26, California had 11 confirmed measles cases across various counties, including San Mateo, Los Angeles, and Orange.
What Officials Are Saying
During a press conference on Friday, Dr. Sarah Rudman, acting health officer and director of the Santa Clara County Public Health Department, stated, “At this point, we don’t know the number of people who may have been exposed. That’s why we’re asking everyone to take a look at these different locations, the specific times when the contagious person was there, and if they understand that they were in that same location at that same time, they are considered exposed.”
Officials are working to identify contacts, but due to the public nature of these locations like the measles exposure San Jose H Mart, the Newark Starbucks, and the Milpitas Trader Joe’s, it’s impossible to name every individual who might have been present.
Dr. Rudman urged those potentially exposed to:
- Check their vaccination records.
- Contact their healthcare provider, especially if they are in high-risk groups. High-risk groups include parents of young infants, pregnant individuals, and those who are unvaccinated, as they face a higher risk of severe complications.
Measles: Highly Contagious, Highly Preventable
Officials emphasized that measles is extraordinarily contagious. “It’s one of the most contagious diseases we know about,” Dr. Rudman said. “We know that the average person with measles can get up to 14 people sick. And you can imagine 14 times 14 times 14 spreading quickly if the population is unvaccinated.”
According to the CDC:
- Measles can remain airborne for up to 2 hours after an infected person leaves an area.
- It’s so contagious that if an infected person is near others who are not immune, up to 90% of those people will also become infected.
Recognizing Measles Symptoms and Taking Action
Dr. Kavita Trivedi, the communications officer for the Alameda County Public Health Department, outlined common measles symptoms and prevention points.
Common measles symptoms include:
- Fever
- Rash
- Red or irritated eyes
- Runny nose
These symptoms typically appear between seven to 21 days after exposure.
If you develop symptoms:
Dr. Trivedi strongly urged the public to contact their healthcare provider before visiting any clinic. “We want to make sure that you call them in advance to let them know you’re coming,” she said. “We want to protect other people in the waiting room, other susceptible people in the health care facility.” This precautionary step is crucial to prevent further spread.
Vaccination: Your Strongest Defense
Both officials reassured residents that vaccination remains the most robust defense against measles. Before the vaccine’s development in the 1960s, measles was extremely common in children. Its significant reduction was a major public health triumph.
“We are very fortunate in the Bay Area to have the benefit of high vaccination rates throughout all of our Bay Area communities,” Dr. Trivedi noted, highlighting that the MMR (measles, mumps, and rubella) vaccine is the most effective prevention. The CDC states that:
- Two doses of the MMR vaccine are 97% effective against measles.
- One dose is 93% effective.
What You Should Do Now
- Check Exposure: If you were at the H Mart in San Jose on May 21, the Starbucks in Newark on May 23, or the Trader Joe’s in Milpitas on May 25, verify the specific exposure times released by health officials.
- Verify Vaccination Status: Check your and your family’s immunization records for the MMR vaccine.
- Contact Your Doctor If Exposed and Unsure/Unvaccinated/High-Risk: If you believe you were exposed and are unvaccinated, unsure of your status, or fall into a high-risk category, contact your healthcare provider for guidance.
- Monitor for Symptoms: Be aware of the symptoms of measles (fever, rash, red eyes, runny nose) for up to 21 days after potential exposure.
- Call Ahead If Symptomatic: If you develop symptoms, call your doctor before going to any clinic or hospital.
Conclusion: Vigilance and Vaccination are Key
This Bay Area measles exposure event is a serious reminder of the importance of vaccination and public health awareness. Measles is highly contagious, but it is also highly preventable through vaccination. By staying informed about potential exposures like those at the measles exposure San Jose, measles exposure Newark Starbucks, and measles exposure Milpitas Trader Joe’s locations, checking our vaccination status, and knowing the measles symptoms and prevention steps, we can all play a part in protecting ourselves and our community. Let’s heed the advice of our public health officials and ensure we’re taking the necessary precautions.
