Measles 101: Protection Starts with Knowing
Measles is a highly contagious disease that can be serious, and in recent years we’ve seen a resurgence of cases in the United States. While measles has been around for a long time and is well understood by medical and public health professionals, it remains an immediately reportable disease in Washington State, with well-established response protocols in place. Measles is also vaccine-preventable: one dose of the MMR vaccine is 93% effective, and two doses are 97% effective.
Because MMR vaccination is required for school attendance in Washington, most people are protected—helping reduce the spread through what’s known as community immunity. However, there are still areas with lower vaccination coverage where outbreaks can spread more easily. The good news is that rapid detection, isolation, and coordination between healthcare providers and Snohomish County public health can effectively stop further spread. Everyone is encouraged to know their immunity status. If you’re unsure or can’t locate your immunization records, a blood test can check for measles antibodies. If you’re not immune and haven’t been exposed, getting an MMR vaccine is a simple and effective way to protect yourself and your community.
