Multiple Measles Cases Confirmed in Colorado, New Jersey amid National Outbreak

Health officials in New Jersey and Colorado have confirmed new cases of measles in out-of-state residents who potentially exposed others in public locations. In New Jersey, a case was identified in Passaic County linked to international travel, with possible exposure on August 1, 2025, and residents are urged to stay current on MMR vaccinations amid a national rise in measles cases. Colorado health departments confirmed a case involving a visitor to the Crest Gift Shop at Monarch Mountain on July 25, with exposure monitoring advised through August 15. Colorado has reported 16 measles cases in 2025, with several hospitalizations but no deaths, and officials emphasize vaccination as the primary defense against the highly contagious virus. Both states recommend individuals who may have been exposed monitor symptoms such as fever, cough, runny nose, red eyes, and rash, and to contact healthcare providers by phone before visiting medical facilities. Public health agencies continue contact tracing and outreach to prevent further spread amid the highest national measles incidence since 1992.
