There are now three confirmed cases of measles in Colorado. All investigations are ongoing and are typically handled at the county level with support from the state.

Colorado has confirmed its second case of measles, this time in Denver. The Colorado Department of Public Health and Environment reports that the patient is an unvaccinated one-year-old who recently traveled to an area in Mexico experiencing an outbreak.

In the state's second measles case of the year, a baby under 1 year old has been confirmed to have the virus. As babies cannot be vaccinated, they are highly vulnerable, health officials warn.

Three cases of measles have now been confirmed in Colorado, and health leaders are encouraging vaccination as one of the best preventative methods to avoid becoming infected with this highly contagious disease.

The Denver patient, an infant under 1 year old, contracted measles during a recent visit to an area of Chihuahua, Mexico, that is currently experiencing an outbreak, according to city and state public health officials.
