St. Louis County Confirms First Measles Case in 20 Years Following Train Exposure
St. Louis County has confirmed its first measles case in 20 years, involving a resident who boarded a train to Chicago in late August. This individual was exposed on a Missouri River Runner (Train 318) that also carried another person later confirmed to have measles by Jackson County health officials. In total, four individuals who rode the train have tested positive for measles. The St. Louis County patient, a teacher from north St. Louis County, is recovering well and has transitioned to virtual classes for isolation. Health officials are actively investigating the case and collaborating with state and local authorities to identify others who may have been exposed. Despite the confirmed case, St. Louis County Health Director Dr. Kanika Cunningham stated that the overall risk for the region remains minimal, and direct contact has been made with identified exposed individuals.
