Vancouver, WA - March 22, 2026 - Clark County Public Health officials confirmed six cases of measles today, marking the first outbreak in the county in several years and sparking concerns about a potential wider resurgence of the highly contagious disease. The cases, linked to events held in the Portland, Oregon metropolitan area, underscore the ongoing risk posed by declining vaccination rates and the ease with which measles can spread across state lines.

This outbreak arrives at a critical juncture. While measles was declared eliminated in the United States in 2000, imported cases and localized outbreaks have become increasingly common in recent years, fueled by a complex interplay of factors, including vaccine hesitancy, misinformation, and disruptions to routine immunization schedules - particularly those experienced during the COVID-19 pandemic.

"We are taking this outbreak very seriously," stated Dr. Anya Sharma, Clark County Public Health Officer, in a press conference this afternoon. "Measles is not a mild illness. It's highly contagious - meaning it spreads easily through the air when an infected person coughs or sneezes - and can lead to severe complications, especially in vulnerable populations like young children and individuals with weakened immune systems. The fact that these cases are linked to events in Portland highlights the importance of regional collaboration in controlling the spread."

Understanding the Threat: Measles and its Complications

Measles presents with a range of symptoms, beginning with high fever, cough, runny nose, and red, watery eyes. A characteristic rash typically appears a few days later, starting on the face and spreading throughout the body. While most people recover from measles, complications can be severe. The Centers for Disease Control and Prevention (CDC) reports that these complications include pneumonia (accounting for a significant percentage of measles-related hospitalizations), encephalitis (inflammation of the brain which can lead to permanent brain damage), and even death. In rare cases, a more severe, degenerative brain disorder called subacute sclerosing panencephalitis (SSPE) can develop years after a measles infection.

Vaccination: The Cornerstone of Prevention

The measles, mumps, and rubella (MMR) vaccine is remarkably effective. Two doses of the MMR vaccine provide approximately 97% protection against measles. The CDC recommends that all children receive their first dose of the MMR vaccine between 12 and 15 months of age, and the second dose between 4 and 6 years of age. Adults born in 1957 or later who have not had measles or been vaccinated should also receive two doses of the MMR vaccine.

However, vaccination rates have been declining in many parts of the United States, creating pockets of susceptibility. The CDC's most recent data shows that national MMR vaccination coverage among kindergarteners is around 93%, still below the 95% needed to achieve herd immunity. Within Clark County, vaccination rates are reportedly slightly below the national average, contributing to the current heightened risk.

Current Response and Public Health Guidance

Clark County Public Health is actively investigating the source of the outbreak and working to identify and contact individuals who may have been exposed. Contact tracing is proving challenging given the linked cases in the Portland area, requiring close collaboration with Oregon health officials.

Public health officials are urging unvaccinated individuals to schedule vaccinations as soon as possible. Those who may have been exposed are advised to monitor for symptoms (fever, cough, runny nose, rash) and to isolate themselves if symptoms develop, contacting their healthcare provider before seeking medical care to avoid potentially exposing others. Healthcare providers are reminded to promptly report suspected cases of measles to the health department.

The outbreak serves as a stark reminder that infectious diseases, while often preventable, remain a constant threat. Addressing vaccine hesitancy through open communication, accurate information, and community outreach will be crucial in preventing future outbreaks and protecting public health. Further updates will be provided as the investigation progresses.
