Measles Resurgence in Snohomish County: A Warning Sign for Washington State?
Snohomish County health officials are battling a growing measles outbreak, now totaling six confirmed cases, and the situation is raising concerns about declining vaccination rates and the potential for wider spread. The latest case, confirmed Tuesday, involves an unvaccinated child exposed during a service at the Slavic Christian Church Awakening in Mukilteo on January 18th. Anyone who attended the church between 2 p.m. and 6 p.m. that day is urged to monitor for symptoms.
The Anatomy of a Measles Outbreak
This outbreak isn’t an isolated incident. It follows a pattern seen across the US and globally, where measles – once considered eradicated – is making a comeback. The Centers for Disease Control and Prevention (CDC) reported 971 cases in 2024 as of March 21st, a significant increase from previous years. The current Snohomish County outbreak originated with cases linked to a family visiting from South Carolina, highlighting how easily the virus can be imported and spread within communities with pockets of unvaccinated individuals.
Why the Rise in Measles Cases Now?
Several factors contribute to this resurgence. A primary driver is declining vaccination rates. Misinformation about vaccine safety, fueled by online sources, has eroded public trust. Additionally, travel – both international and domestic – facilitates the spread of the virus. The highly contagious nature of measles means that 90% of people who aren’t immune will contract the disease when exposed.
The current outbreak underscores the importance of herd immunity – the protection afforded to those who cannot be vaccinated (infants, individuals with certain medical conditions) when a large percentage of the population is immune. When vaccination rates fall below the threshold needed for herd immunity (around 95%), outbreaks become more likely.
Beyond Snohomish County: A Statewide and National Trend
Washington State isn’t alone. Several states are currently experiencing measles outbreaks, including Ohio, Florida, and Arizona. This suggests a broader national trend. Public health officials are concerned that if vaccination rates don’t improve, measles could become endemic again in the US, meaning it’s constantly present within the population.
The economic impact of outbreaks also shouldn’t be overlooked. Outbreaks require significant public health resources for investigation, contact tracing, and vaccination campaigns. Schools and workplaces may need to close, leading to lost productivity and economic disruption.
What You Need to Know: Symptoms and Prevention
Measles symptoms typically appear 7-14 days after exposure and include:
- High fever (often above 104°F)
- Cough
- Runny nose
- Red, watery eyes
- Tiny white spots inside the mouth (Koplik’s spots)
- A rash that spreads from the head to the body
The MMR (measles, mumps, and rubella) vaccine is highly effective. Two doses are recommended for most individuals. People born before 1957 are generally considered immune due to widespread exposure to measles before the vaccine was available.
What to Do If You Suspect Exposure
If you believe you may have been exposed to measles, it’s crucial to:
- Check your vaccination records.
- Contact your healthcare provider immediately, before visiting a clinic or hospital, to discuss your concerns and arrange for testing.
- Self-isolate to prevent potential spread.
FAQ: Measles and Vaccination
Q: Is the MMR vaccine safe?

Q: What if I’m pregnant and exposed to measles?
A: Exposure to measles during pregnancy can be dangerous. Contact your healthcare provider immediately.
Q: Where can I find more information about measles?
A: The CDC (https://www.cdc.gov/measles/) and the Washington State Department of Health (https://www.doh.wa.gov/emergencies/communicable-diseases/measles) are excellent resources.
The Snohomish County outbreak serves as a stark reminder of the importance of vaccination. Protecting ourselves and our communities requires a collective effort to maintain high vaccination rates and combat misinformation. Staying informed and proactive is key to preventing further spread and safeguarding public health.
