A visitor from out of state stopped at the gift shop atop Monarch Pass last week while contagious with measles, possibly exposing others who shopped there.
People could have encountered the measles virus at the Monarch Mountain at the Crest Gift Shop, 24500 U.S. 50, east of Salida, between 4:30 and 7 p.m. July 25.
Anyone who visited the shop during that window should watch for symptoms through Aug. 15, according to the Colorado Department of Public Health and Environment.
Symptoms of measles include a fever, cough, runny nose, red eyes and a rash that usually starts on the face. The rash typically appears about four days after a person becomes contagious, meaning that people who were exposed to the virus could spread it while thinking they have the flu or some other illness.
The state health department urged people who could have measles to call ahead before seeking care, so the clinic or hospital can take steps to protect other patients.
Two doses of the measles vaccine reduce the odds of getting the virus by about 97%.
The department didn’t release any information about the visitor.
The state has found 16 measles cases this year, including four people who needed hospital care. In a typical year, it has two or fewer cases.
