Measles Exposure at Broomfield High School Prompts Investigation
Locales: Colorado, UNITED STATES

Broomfield, Colorado - February 28th, 2026 - A potential measles outbreak is brewing in Broomfield, Colorado, following a confirmed exposure at Broomfield High School earlier this week. Health officials from the Tri-County Health Department are actively investigating the situation, and are urging residents to take preventative measures, particularly vaccination.
The initial exposure occurred on Monday, February 26th, 2026, between 7:30 AM and 4:00 PM within the Broomfield High School building. Authorities believe the infected individual was present during peak school hours, potentially exposing a significant number of students, staff, and potentially even visitors. While the specific details of the individual - age, vaccination status, and how they contracted the virus - remain confidential to protect their privacy, health officials confirmed this is not an isolated incident, and are monitoring for secondary cases.
Understanding the Threat: Measles - A Highly Contagious Virus
Measles, also known as rubeola, is a highly contagious viral illness spread through respiratory transmission - coughing and sneezing. It's so contagious that if one person has measles, 90% of those who are not immune around them will also become infected. This makes even brief exposure a cause for concern. The virus remains airborne for extended periods and can linger on surfaces, increasing the risk of transmission.
The symptoms of measles typically appear 7-14 days after exposure, starting with a high fever (often exceeding 104?F), a persistent cough, a runny nose (coryza), and conjunctivitis (red, watery eyes). A characteristic rash then develops, usually starting on the face and spreading down the body. This rash is often described as blotchy and red and is a key indicator of the infection. While the rash itself isn't usually itchy, it's a visible sign of a serious illness.
Complications from measles can be severe, particularly for infants and young children, pregnant women, and individuals with compromised immune systems. These complications can include ear infections, pneumonia, encephalitis (inflammation of the brain), and even death. In rare cases, a delayed complication called Subacute Sclerosing Panencephalitis (SSPE) can develop years after the initial infection, leading to neurological damage.
Public Health Response and Vaccination Efforts
The Tri-County Health Department is actively tracing potential contacts of the confirmed case at Broomfield High School, notifying those who may have been exposed, and offering guidance on symptom monitoring. School officials are cooperating fully with the investigation and have increased cleaning and disinfection protocols throughout the building.
However, officials are stressing that the most effective defense against measles is vaccination. The measles, mumps, and rubella (MMR) vaccine is highly effective - two doses provide approximately 97% protection against measles. The CDC recommends that children receive their first MMR dose 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 haven't had measles or been vaccinated should also receive two doses of the MMR vaccine.
"We're seeing a worrying trend of declining vaccination rates nationally, and unfortunately, Colorado is not immune to that," stated Dr. Emily Carter, Chief Medical Officer for the Tri-County Health Department. "This exposure at Broomfield High School is a stark reminder of the importance of vaccination in protecting our community. Measles is preventable, and we urge everyone to check their vaccination records and ensure they are up-to-date."
The health department has scheduled a free MMR vaccination clinic at the Broomfield Community Center on March 3rd and 4th to address the potential surge in demand. They are also encouraging residents to contact their primary care physicians or local pharmacies to schedule appointments.
Beyond Broomfield: A National Concern
The incident in Broomfield is part of a broader national pattern. The CDC has reported a significant increase in measles cases in recent years, linked to decreasing vaccination rates and increased international travel. Outbreaks have been reported in several states, raising concerns about the potential for a wider resurgence of the disease. Health experts attribute the decline in vaccination rates to a combination of factors, including misinformation about vaccines and access barriers to healthcare.

Early detection and prompt vaccination are crucial in preventing the spread of measles and protecting the health of the community.
