PRP High illnesses split Louisville reports on hospital count and cause

Louisville, KentuckyPublished 29 Sep 2026

People fell ill Monday at Pleasure Ridge Park High School’s tech building. JCPS later described a dried-out chemistry-lab P-trap. Outlets disagree on how many students went to the hospital and whether a cause is settled.

On Monday, Sept. 21, 2026, people became ill at Pleasure Ridge Park High School in Louisville’s Pleasure Ridge Park neighborhood, in the tech building. Symptoms included nausea, headaches, and fainting. Spectrum News 1 and a JCPS count reported by Shay Informed said six students were taken to the hospital. WSMV said twenty-two students were taken, and Shay Informed said Norton Healthcare saw 22 patients. WDRB said 22 people were treated for illness at the school. JCPS later said testing found a dried-out P-trap in a chemistry lab and described sewer gas as a possible or likely path. Spectrum and WSMV said the water seal was restored. WDRB said JCPS had not confirmed an official cause, WSMV said the investigation was still open, and Shay Informed quoted a letter saying no evidence identified the P-trap, food, water, or trash as the cause. THC-infused candy wrappers were an early lead. Shay Informed also reported a Norton document listing accidental carbon monoxide exposure, a negative carboxyhemoglobin test, and Barnard Baker saying fire tests did not detect carbon monoxide.
