Measles Exposure Expands to Denver, Glendale, and Windsor Grocery Stores — Here’s What to Know
Health officials are warning of new measles exposure sites in Colorado, tied to an ongoing outbreak that began with an out-of-state traveler who arrived at Denver International Airport last month. A second vaccinated adult in Denver County has now tested positive. That person had been aboard Turkish Airlines Flight 201, which landed at DIA on May 13.
So far, the case count has reached seven, including four passengers from the flight and three others exposed at the airport on May 14. While the infected Denver resident is recovering at home, CDPHE is urging residents to check their vaccine status and monitor for symptoms. Measles is extremely contagious, spreading easily through coughs and sneezes, and can linger in the air for up to two hours. Two doses of the MMR vaccine are about 97% effective, though breakthrough cases can still happen, usually with milder symptoms and reduced spread.
Below are the newest exposure sites linked to the most recent Denver case:

Officials say additional exposure locations have been identified across Aurora, Colorado Springs, Denver, Evergreen, Glendale, Grand Junction, Greenwood Village, and Windsor. The full list is available on the CDPHE website.
Measles symptoms usually appear 7–21 days after exposure and may include high fever, cough, runny nose, and rash. If you were at any listed site during the exposure window and start experiencing symptoms, contact a healthcare provider before visiting to help prevent further spread. If you don’t have a provider, call an urgent care or ER and explain the possible exposure.
According to CDPHE, the last measles case in Colorado before this outbreak was in December 2023. Most cases are linked to travel or occur in under-vaccinated communities. Currently, only 93.7% of Colorado children have received the MMR vaccine — below the 95% threshold for herd immunity.
