DEVELOPING: Officials are warning residents of South Denver Metro of a possible measles exposure and have issued an alert to anyone who recently visited Target, King Soopers or any of five other locations in the region after a baby with measles was at all of those places sometime last week.

According to reports, Tri-County Health Department Executive Director Dr. John Douglas stated that measles is the most infectious of infectious diseases. It’s a respiratory infection and spread by coughing and sneezing. The baby was at locations in Denver, Parker, Lone Tree, Littleton and Highlands Ranch. The health department has apparently contacted nearly every person known to have been in contact with the baby. The department is now notifying the public out of an abundance of caution.
