Colorado has reported 10 measles cases this year, linked to an outbreak at Denver International Airport (DIA). Three new cases were confirmed, bringing the total number of infected individuals to 13.
Two of the new cases were unvaccinated adults who visited DIA on May 14. They developed symptoms and are recovering at home. A third case was a vaccinated resident who contracted measles after being exposed to an infected passenger on Turkish Airlines flight 201, which landed at DIA on May 13.
The Centers for Disease Control and Prevention (CDC) defines an outbreak as three linked cases in a state. Although the CDC has deemed this outbreak, health officials believe the virus has not spread widely within the community.
Residents who visited specific locations during the same period are advised to monitor their symptoms. These include Love’s Travel Stop, Maverick Gas Station, and King Soopers. Public health officials have provided guidance for those exposed.
Measles can be prevented by receiving two doses of the vaccine, which is approximately 97% effective. The virus typically causes fever, cough, runny nose, red eyes, and a rash that develops four days after becoming contagious.
Colorado’s measles cases are rare, with only two or fewer cases reported in typical years. The state’s last outbreak occurred in the 1990s, when more than 10 cases were recorded annually.
