Vaccinated adult from Colorado infected with measles, the state’s first “breakthrough” case this year

Colorado on Friday reported its fifth incidence of measles this year, and, for the first time in the spate of cases, the infection was in a person who had been vaccinated against the disease.

The person, an adult living in Denver, had recently traveled to the Mexican state of Chihuahua, which is seeing an outbreak of measles. Two other cases identified in Colorado — one in a baby in Denver and another in a Pueblo resident — were also connected to travel to Chihuahua.

The Colorado Department of Public Health and Environment identified one location where people may have been exposed to the virus as a result of this case.

Anyone who was at the Kaiser Permanente urgent care clinic at 8383 W. Alameda Ave. in Lakewood between 10:30 a.m. and 1 p.m. on Saturday, April 19, should monitor themselves for symptoms for 21 days and consider avoiding public gatherings.

If you think you may be sick with measles, call ahead to your doctor’s office or emergency clinic before going in to allow the staff to make sure you can be seen without risk of exposing others.
