Clark County Identifies New Measles Exposure Site
Locales: Washington, UNITED STATES

Vancouver, WA - January 31st, 2026 - Clark County Public Health officials announced today a new potential measles exposure site, adding to the growing concern surrounding the ongoing measles outbreak in the region. This latest development underscores the highly contagious nature of the disease and reinforces the critical need for vaccination. While specific location details and dates/times have been temporarily redacted to protect individual privacy during contact tracing, health officials emphasize the importance of vigilance and proactive health measures.
This isn't an isolated incident. Measles, once considered largely eradicated in the United States thanks to widespread vaccination, has been making a concerning resurgence in recent years. The current outbreak in Clark County follows a pattern seen nationally and globally - a decline in vaccination rates coupled with international travel contributing to the re-introduction and spread of the virus. While cases have been relatively contained until now, the identification of another exposure site suggests the outbreak is expanding, and officials fear a wider community impact if preventative steps aren't taken.
Understanding the Threat: Measles and Its Impact
Measles is a highly contagious viral infection spread through respiratory droplets produced when an infected person coughs or sneezes. It's so contagious that if one person has measles, 90% of those who are not immune and are exposed will also become infected. This makes rapid response and containment crucial. Symptoms typically manifest 7-14 days after exposure, beginning with a fever, cough, runny nose, and conjunctivitis (red, watery eyes). This is followed by the characteristic rash, which usually starts on the face and spreads throughout the body. While often described as simply a childhood illness, measles can lead to serious complications, including pneumonia, encephalitis (brain swelling), and even death. Young children, pregnant women, and individuals with compromised immune systems are particularly vulnerable.
The Power of Prevention: Vaccination Remains the Best Defense The cornerstone of measles prevention is vaccination. The measles, mumps, and rubella (MMR) vaccine is remarkably effective, providing approximately 97% protection with two doses. The CDC recommends that 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 been vaccinated or do not have evidence of immunity should also receive the MMR vaccine. Health officials are strongly urging anyone unsure of their vaccination status to contact their healthcare provider or local health department.
"We are deeply concerned about this expanding outbreak," stated Dr. Emily Carter, Clark County Public Health Officer. "Vaccination is not just about protecting yourself; it's about protecting vulnerable members of our community who cannot be vaccinated, such as infants too young to receive the vaccine or individuals with certain medical conditions. It's a collective responsibility."
Outbreak Investigation and Ongoing Efforts
Public health officials are working tirelessly to trace the source of the current outbreak and identify all individuals who may have been exposed. This includes reviewing medical records, conducting interviews with confirmed cases, and meticulously mapping potential exposure sites. The process is complex and requires significant resources. The redacted details regarding the new exposure site are being carefully managed to allow for thorough investigation and individual notification while maintaining privacy.
The Washington State Department of Health is providing support to Clark County, offering additional expertise and resources to aid in the investigation and response. The CDC is also monitoring the situation closely, offering guidance and assistance as needed.
