Colorado health officials have issued an urgent public health warning following the confirmation of a second measles case involving an unvaccinated student at Broomfield High School. This latest development underscores the critical importance of vaccination in preventing the spread of this highly contagious disease. Residents in Broomfield and Westminster are advised to remain vigilant and monitor for symptoms, especially if they visited specific public locations during potential exposure periods. This marks the second measles incident linked to the school and highlights ongoing concerns about community immunity.
Second Measles Case Confirmed at Broomfield High School
The Colorado Department of Public Health and Environment (CDPHE) and the Adams County Health Department recently confirmed a new measles infection. This new case is the second at Broomfield High School and the third statewide this year, with all confirmed individuals being unvaccinated against the virus. The first case linked to the school was identified just last week. Health officials stress that neither student had received the measles, mumps, and rubella (MMR) vaccine. This detail is central to the ongoing public health response.
Broomfield, a community situated approximately 15 miles northwest of Denver, is now on high alert. The rapid confirmation of multiple cases in a single school setting raises concerns about potential further transmission within the broader community. The focus remains on containing the spread and protecting vulnerable populations.
Understanding Measles: A Highly Contagious Threat
Measles is an extremely contagious respiratory disease. It is caused by a virus that spreads easily through the air when an infected person coughs or sneezes. Dr. Ned Calonge, chief medical officer for the CDPHE, highlights its rapid transmission among unimmunized populations. The virus can remain airborne for up to two hours after an infected person has left a location. This means that numerous individuals could be exposed without direct contact with the infected person.
Symptoms typically manifest within 21 days of exposure. They commonly begin with a high fever, followed by a cough, runny nose, and red, watery eyes. A distinctive rash then appears several days later. This rash usually starts on the face and spreads down to the rest of the body. An individual infected with measles is contagious for four days before the rash appears and for four days after it erupts. However, measles only spreads from symptomatic individuals.
Critical Exposure Locations and Times in Broomfield & Westminster
Public health authorities have identified several key locations and specific timeframes where potential measles exposure may have occurred. Individuals who were present at these sites during the listed times are strongly urged to monitor their health for the next 21 days. Symptoms from the latest possible exposure could develop through March 18, 19, and 20.
The identified exposure locations include:
Broomfield High School: 1 Eagle Way, Broomfield, CO. Potential exposure between 8 a.m. and 6 p.m. on February 24, 25, 26, or 27.
Chick-fil-A: 4260 W. 121st Ave., Broomfield, CO. Potential exposure on Wednesday, February 25, from 11:30 a.m. to 2 p.m.
Chipotle: 5160 W. 120th Ave., Westminster, CO. Potential exposure on Thursday, February 26, from 11:30 a.m. to 2 p.m.
If you suspect you may have been exposed, it is crucial to avoid public gatherings and high-risk settings. Contacting a healthcare provider immediately is the recommended first step.
Immediate Steps for Potential Exposure and Prevention
If you believe you or a family member may have been exposed to measles, prompt action can be vital. Health officials advise contacting your healthcare provider or a doctor without delay. This is particularly important if you are unvaccinated for measles, mumps, and rubella (MMR).
For unvaccinated individuals, post-exposure prevention methods are available:
MMR Vaccine: Receiving the MMR vaccine within 72 hours of exposure can potentially prevent the illness entirely. It can also significantly reduce its severity. This option is effective before symptoms appear.
Immunoglobulin (IG): In certain circumstances, an immunoglobulin treatment may be administered. This treatment, given within six days of exposure, can also help to prevent or lessen the severity of the illness. This is often recommended for vulnerable individuals, such as infants or those with compromised immune systems.
Early intervention is key to mitigating the risks associated with measles infection. Do not wait for symptoms to appear if you suspect exposure.
The Role of Vaccination and Herd Immunity
Vaccination remains the most effective defense against measles. The U.S. Centers for Disease Control and Prevention (CDC) reports that one dose of the MMR vaccine provides approximately 93% protection. A second dose boosts this protection to about 97%. This high efficacy rate is why widespread vaccination is critical for public health.
The concept of “herd immunity” is also vital. This occurs when a large enough percentage of a population is immune to a disease. This immunity provides indirect protection to those who cannot be vaccinated. Public health experts typically recommend a 95% vaccination rate to achieve effective herd immunity for measles.
The Boulder Valley School District, which includes Broomfield High, reported an MMR vaccination rate of 95.7%. While this exceeds the recommended 95% threshold, cases can still emerge. Even with high rates, a small percentage of unvaccinated individuals still represents a “sizable number of susceptible individuals,” as noted by Dr. Ned Calonge. This creates continued risk for outbreaks, especially in highly interconnected environments like schools.
School Protocols and Student Exclusions
In response to the confirmed cases, Broomfield High School has implemented strict protocols. Principal Ginger Ramsey communicated directly with parents regarding these measures. Initially, 42 students were excluded from attending classes due to unverified vaccination status. This number was later reduced to 26 after authorities verified vaccination records.
Under Colorado law, students who are unvaccinated or unable to provide proof of immunity are subject to exclusion from school. This exclusion can last for up to 21 days following an exposure. Principal Ramsey strongly encouraged vaccination as a measure to minimize exclusion from school and other activities. Further measles cases at the school could prolong the quarantine period for unvaccinated or immunocompromised students.
The Boulder Valley School District confirmed its adherence to public health agency guidance regarding quarantines and exclusions. While some games have been rescheduled due to student exclusions, the district has not suggested canceling or modifying upcoming spring sports or other school events. The district is also developing plans to provide academic support to students who may be excluded.
Risks and Complications of Measles
While most people recover from measles within two to three weeks, the virus can lead to serious complications. Unvaccinated individuals face significant risks, as highlighted by Dr. Jessica Cataldi, a pediatric infectious disease specialist at Children’s Hospital Colorado. Potential complications include:
Ear infections: A common complication that can sometimes lead to permanent hearing loss.
Pneumonia: A severe lung infection, often requiring hospitalization.
Seizures: Measles can, in rare cases, cause brain swelling and seizures.
Immune amnesia: Measles can temporarily suppress the immune system, making individuals more susceptible to other infections.
Brain damage: A very rare but devastating complication known as subacute sclerosing panencephalitis (SSPE) can occur years after infection.
- Death: Measles can be fatal, especially in young children and those with weakened immune systems.

CDPHE advises individuals vaccinated against measles before 1968 to consult their healthcare providers about a booster shot. Earlier vaccines were less effective. Getting vaccinated is universally recognized as the best way to protect yourself, your family, and your community from these severe outcomes.
Frequently Asked Questions
What are the common symptoms of measles and when should I seek medical help?
Measles symptoms typically begin with a high fever, cough, runny nose, and red, watery eyes. A distinct rash then usually develops three to five days later, starting on the face and spreading to the rest of the body. Symptoms can appear up to 21 days after exposure. If you or someone you know develops these symptoms, especially after potential exposure at Broomfield High School, Chick-fil-A, or Chipotle on the specified dates, contact your healthcare provider immediately. Early diagnosis and intervention are crucial to prevent further spread and manage potential complications.
Where were the potential measles exposure sites in Broomfield and Westminster?
Colorado health officials identified several specific locations where the public might have been exposed to measles. These include Broomfield High School (1 Eagle Way, Broomfield) from 8 a.m. to 6 p.m. on February 24, 25, 26, or 27. Additional sites are Chick-fil-A (4260 W. 121st Ave., Broomfield) on Wednesday, February 25, from 11:30 a.m. to 2 p.m., and Chipotle (5160 W. 120th Ave., Westminster) on Thursday, February 26, from 11:30 a.m. to 2 p.m. Anyone at these locations during these times should monitor their health for 21 days.
What should I do if I think I’ve been exposed to measles and am unvaccinated?
If you are unvaccinated for measles, mumps, and rubella (MMR) and believe you may have been exposed, it is critical to act quickly. Contact your doctor or a healthcare provider immediately. You might be eligible for post-exposure prophylaxis. The MMR vaccine can be given within 72 hours of exposure to potentially prevent or lessen the illness. In some cases, immunoglobulin (IG) can be administered within six days of exposure for the same purpose, especially for vulnerable individuals. Avoid public gatherings and self-monitor for symptoms for 21 days.
A Call to Action for Community Health
The current situation in Broomfield highlights the persistent threat of vaccine-preventable diseases. Colorado has reported measles cases in Adams, Arapahoe, and Broomfield counties this year, contributing to over 1,000 confirmed infections nationwide. This serves as a stark reminder that even with generally high vaccination rates, pockets of unvaccinated individuals can lead to outbreaks.
The CDPHE continues to emphasize that “Getting vaccinated is the best way to protect yourself, your family, and your community.” If you are unsure about your or your child’s vaccination status, consult your healthcare provider or utilize the state’s online immunization portal. Staying informed, taking preventive measures, and ensuring up-to-date vaccinations are the strongest defenses against measles and its potential severe complications. Let’s work together to protect our community.
