DENVER (KDVR) — The Colorado Department of Public Health and Environment has issued an exposure alert to the public for those who might have been exposed to measles.

The CDPHE issued an exposure alert on Saturday, providing exposure locations within the cities of Grand Junction and Fruita, located in Mesa County.

This comes after Colorado health officials confirmed a case of measles in an adult resident within Mesa County on Aug. 15. Officials had previously said the adult resident had no “known connection to other recent exposures reported in Colorado and has not traveled outside the state.”

The public exposure locations, dates, times and when possible symptoms may occur, provided by CDPHE are the following:

Measles symptoms can take up to 21 days to show up after exposure, which can begin with fever, cough, runny nose, and red eyes, followed by a rash that usually starts several days later.

Health officials say that measles is a highly contagious but preventable disease through vaccinations.

CDPHE said that the exposure alerts ” allow Coloradans to get the information they need most quickly, where exposures have occurred, and what action to take.”
