Colorado Confirms Second Measles Case Tied to Broomfield High School

Officials warn of potential exposure at two busy restaurants, urging post-exposure MMR within 72 hours.

Overview

State health authorities reported a second linked infection involving an unvaccinated Adams County student connected to last week’s Broomfield High School case.
Potential exposure was identified during lunch at the Chick-fil-A on Feb. 25 in Broomfield and the Chipotle on Feb. 26 in Westminster.
Anyone at Broomfield High School from 8 a.m. to 6 p.m. on Feb. 24–27 may have been exposed, and unvaccinated students and staff were instructed to stay home starting Friday.
Health guidance includes MMR vaccination within 72 hours of exposure, immunoglobulin within six days for high‑risk contacts, and calling a provider before seeking in‑person care if symptoms arise.
Officials are notifying contacts and assessing additional sites, with symptom watch windows extending into March 18–20 during a broader U.S. measles surge approaching 1,000 cases this year.
