The Colorado Department of Public Health and Environment (CDPHE) and Lake County Department of Public Health and Environment have identified a case of measles in an unvaccinated child from Lake County. The individual recently traveled to Orlando, Florida. Travel to this area has been associated with other recent measles cases in the U.S. Be aware of measles risk in light of the recent spring break travel season.
New exposure locations are listed on the CDPHE measles exposures website .
Public health has detected measles virus in a wastewater sample from a Broomfield County wastewater utility. A wastewater detection of measles virus indicates that one or more people with a recent measles infection have been in the area. Though we haven't seen an increasing trend of measles in wastewater in Broomfield, the initial detection warrants notification to providers with a reminder that unidentified cases and exposures may occur. The last reported measles case in Broomfield County was in March 2026.

Measles is a highly Contagious respiratory virus that can survive in the air and on surfaces for up to two hours. Measles isn’t just a little rash. Measles can be dangerous, especially for babies and young children.
The most recognizable measles symptom is a very high fever accompanied by a red or brownish blotchy rash that typically starts on the face, although this is not the only symptom.
Before the rash appears, children with measles develop cold-like symptoms, including:
• Cough
• Runny nose
• Fever
• Red, watery eyes
These symptoms tend to get worse during the first 1 to 3 days of the illness.
If you have further questions, call our office and ask to speak to one of our nurses, or to schedule to update your child’s vaccinations please call 970-375-0100 opt 4.
