The adult patient — Colorado’s fifth confirmed measles case this year — visited the Kaiser urgent care clinic at 8383 W. Alameda Ave. People who spent time in the clinic between 10:30 a.m. and 1 p.m. Saturday could have encountered the virus.

The year's fifth case of measles has been confirmed in Colorado, health officials announced Friday. The adult from Denver County had received the MMR vaccine, according to the Colorado Department of Public Health and Environment.

A fifth case of measles is now confirmed in Colorado. It's the third case in Denver. An adult got measles after traveling to Chihuahua, Mexico -- which is seeing an outbreak right now. That person had received a vaccine at some point.
