The measles outbreak tied to two schools in Broomfield is now up to as many as 10 cases, with two new confirmed infections and one suspected infection reported Thursday.
The new cases involve people who live in the same house as a child previously confirmed to have measles, the Colorado Department of Public Health and Environment said in a news release. Two of these so-called household contacts are unvaccinated and, in keeping with public health protocols, have been told to quarantine. That means they are not suspected of exposing anyone in the public to the disease.
But the third suspected case was vaccinated and was not under a quarantine order. CDPHE said people who were at the Bout Time Pub & Grub at 5225 W. 80th Ave. in Arvada on Tuesday, March 10, between the hours of 8 p.m. and 12:30 a.m. may have been exposed to measles.
CDPHE maintains a list of all current places where people may have been exposed to measles on its website.
People who may have been exposed to measles should watch for symptoms to emerge within 21 days of the exposure. Initial symptoms may include fever, cough, runny nose or red eyes, followed later by the telltale red rash. People who develop possible measles symptoms should call CDPHE at 720-653-3369 or their local public health agency. They should call ahead to the hospital or clinic before seeking medical attention.
The Broomfield outbreak is linked to both Broomfield High School and Broomfield Heights Middle School. Unvaccinated students, staff and visitors have been told to stay away from the schools for 21 days to prevent the outbreak from spreading further.
Colorado has now reported 11 confirmed or suspected measles cases in 2026, a number quickly catching up to the 36 cases reported in all of 2025. All confirmed cases so far this year are in unvaccinated children between the ages of 5 and 17. There have so far been no hospitalizations and no deaths.
