Greeley, Colorado - March 19th, 2026 - A growing measles outbreak centered in Weld County, Colorado, is raising significant concerns among public health officials, prompting a heightened alert from University of Colorado Health (UCHealth) and a call for increased vaccination rates statewide. The outbreak, initially identified in the Loveland area, has demonstrated a concerning pattern of spread, pushing the Colorado Department of Public Health and Environment (CDPHE) to mobilize resources and implement containment strategies.

As of today, the CDPHE has confirmed 27 cases within Weld County, with suspected cases under investigation in neighboring Adams and Arapahoe counties. The patients range in age from 8 months to 45 years, and preliminary investigations indicate a lack of complete vaccination coverage is a common thread. Several cases are linked to a community event held earlier this month, suggesting potential for broader community transmission.

"Measles is one of the most contagious diseases known to humankind," explains Dr. Emily Carter, spokesperson for the CDPHE. "A single infected person can spread the virus to up to 90% of those who are not immune. This is why even a small number of cases can quickly escalate into a larger outbreak, particularly in areas with lower vaccination coverage."

UCHealth has issued a system-wide alert to its staff, mandating strict adherence to infection control protocols. Emergency departments are being prepped for a potential influx of patients exhibiting measles symptoms - a high fever, persistent cough, runny nose, conjunctivitis (red, watery eyes), and a characteristic rash that typically begins on the face and spreads throughout the body. Patients are strongly advised to call their healthcare provider before seeking in-person care, allowing providers to implement precautionary measures to protect other patients and staff.

The resurgence of measles in Colorado, and across the nation, is a complex issue with roots extending beyond simply vaccine availability. While Colorado declared measles elimination in 2000, a steady erosion of herd immunity over the last two decades, fueled by a combination of waning immunity from older vaccinations and increasing vaccine hesitancy, has left the population more vulnerable. The CDPHE is now analyzing data to determine the vaccination status of confirmed cases and identify specific pockets of low immunity.

"We've seen a worrying trend of misinformation surrounding vaccines, leading some individuals to delay or forgo vaccination for themselves or their children," Dr. Carter stated. "These decisions aren't just personal; they have public health consequences. Measles isn't a mild illness. It can lead to serious complications such as pneumonia, encephalitis (brain swelling), and even death, especially in young children and individuals with compromised immune systems."

The current outbreak also highlights the role of international travel. Several of the initial cases were linked to travelers returning from countries where measles is still endemic. The CDPHE urges anyone traveling internationally to ensure they are fully vaccinated against measles, and to consult with their doctor at least six weeks before departure to allow time for immunity to develop.

The CDPHE is collaborating with local public health agencies to conduct contact tracing, identify potential exposures, and offer vaccination clinics. Mobile vaccination units are being deployed to underserved communities and areas with low vaccination rates. They are also actively working to debunk common myths and provide accurate information about measles and the importance of vaccination.

Looking forward, public health officials are bracing for a potentially challenging spring and summer. Experts predict that if vaccination rates don't improve, this outbreak could continue to grow, potentially impacting schools, childcare facilities, and other public spaces. The CDPHE stresses that vaccination is the most effective means of preventing measles and protecting the health of the community. They implore all residents to review their vaccination records and schedule an appointment to receive the MMR (measles, mumps, and rubella) vaccine if they are not fully vaccinated or are unsure of their vaccination status.
