Colorado Health Officials Identify More Cases of Measles Connected to Broomfield Schools, Expand Potential Exposure Locations
Seven measles cases linked to unvaccinated students at Broomfield schools have exposed multiple public sites, including Denver International Airport, state health officials said.
- On March 6, 2026, the Colorado Department of Public Health and Environment reported four additional measles cases, raising the outbreak to seven linked to Broomfield High School or Broomfield Heights Middle School.
- Unvaccinated patients tied to Broomfield High School or Broomfield Heights Middle School, health officials said, linked to earlier cases in Adams County.
- Denver International Airport was named among exposure sites on Feb. 16, and CDPHE listed about 11 possible locations across Broomfield, Lafayette, Louisville and Westminster.
- Boulder Valley School District said 80 students, staff and volunteers are excluded, with unvaccinated individuals required to stay home for a 21-day incubation period.
- Health officials urged exposed people to monitor symptoms through March 20; two doses of MMR vaccine reduce infection odds by about 97%, but the 72-hour window for post-exposure MMR has passed and immunoglobulin within six days may help.
