Washington State Faces Growing Measles Outbreak: 124 Cases Confirmed
Locales: Pennsylvania, Ohio, Michigan, Illinois, UNITED STATES

OLYMPIA, WA - February 1, 2026 - Washington State is facing a significant public health challenge as a measles outbreak continues to spread, with the Washington State Department of Health (DPH) confirming a total of 124 cases as of January 31, 2026. This represents a substantial increase from initial reports in late 2025 and signifies the largest measles outbreak in the state in recent history. The outbreak, initially concentrated in Clark County, is now being reported across multiple counties, prompting urgent calls for vaccination and increased vigilance from health officials.
Measles, a highly contagious viral infection, presents a serious threat, particularly to vulnerable populations like young children, pregnant women, and individuals with weakened immune systems. Symptoms typically begin with fever, cough, runny nose, and conjunctivitis (red eyes), followed by a characteristic rash that spreads from the head to the body. While most people recover, measles can lead to severe complications, including pneumonia, encephalitis (brain swelling), and even death. The highly contagious nature of the virus - spread through respiratory droplets produced by coughing or sneezing - means that one infected person can easily transmit the disease to a large number of unvaccinated individuals.
Dr. Emily Carter, Washington State Health Officer, emphasized the preventable nature of the disease. "Measles is preventable with vaccination. This outbreak underscores the critical importance of maintaining high vaccination rates to protect our communities. We strongly encourage everyone who is not vaccinated, or who is unsure of their vaccination status, to get the MMR (Measles, Mumps, and Rubella) vaccine as soon as possible," she stated. The MMR vaccine is highly effective, providing approximately 97% protection against measles after two doses.
The DPH believes the current outbreak is fueled by a confluence of factors. Increased international travel, particularly to regions where measles is endemic, is considered a primary contributor. Travelers can unknowingly bring the virus back to Washington, where it can quickly spread within unvaccinated communities. However, a more concerning trend is the decline in vaccination rates observed in certain areas of the state. This decline, linked to vaccine hesitancy and misinformation, has created pockets of susceptibility, allowing the virus to gain a foothold and proliferate.
Local health departments are working tirelessly with healthcare providers to ramp up vaccination efforts. Mass vaccination clinics are being organized, and public awareness campaigns are being launched to address concerns and provide accurate information about the safety and efficacy of the MMR vaccine. The DPH is also actively tracing the source of the outbreak, investigating each case to identify potential transmission chains and implement targeted interventions. This includes contact tracing, where health officials identify and notify individuals who may have been exposed to the virus.
The economic impact of the outbreak extends beyond healthcare costs. Schools and daycare centers may experience closures due to confirmed cases, disrupting education and creating childcare challenges for working families. Businesses may also suffer from reduced productivity as employees stay home sick or care for ill children. The cost of controlling the outbreak - including investigation, vaccination campaigns, and medical treatment - will place a further strain on public health resources.
Experts warn that the situation could worsen if vaccination rates don't improve. A sustained decline in immunity could lead to a resurgence of measles, transforming it from a preventable disease into a common occurrence. This would not only endanger the health of individuals but also undermine the progress made in eliminating measles as a public health threat.
The DPH urges any individual experiencing symptoms consistent with measles - fever, cough, runny nose, red eyes, and rash - to stay home, isolate themselves from others, and contact their healthcare provider immediately. Early diagnosis and prompt medical attention are crucial to prevent complications and limit further spread of the virus. Washingtonians are also encouraged to review their vaccination records and ensure they and their families are adequately protected. Resources and information about measles and vaccination are available on the DPH website and through local health departments.
