Twenty-three more students fell ill Friday at McClintock Middle School, and school officials said the cause remains a mystery.
Symptoms appeared to be the same as the ones experienced by 12 students at the school on Thursday, Principal Mark McHugh said in a message to parents.
“Some symptoms today included nausea and vomiting, along with dizziness and lightheadedness,” McHugh said.

Medic arrived to evaluate the students, but the cause of the illness has yet to be determined, according to the principal.
One adult also was checked on Friday by Medic and the school’s nursing supervisor, McHugh said.
Fire department crews checked carbon monoxide levels and found everything to be normal, McHugh added. “Our school is also seeking guidance and monitoring from the Mecklenburg County Health Department’s Communicable Disease and Environmental Health Divisions,” he said.
On Thursday, the school’s HVAC system was being repaired and was not functioning properly to cool the 6th-grade wing of the building, the principal said.
“Many of our student illnesses appeared to have been heat-related at that time,” McHugh said. “CMS Building Services completed the HVAC repair by Thursday afternoon. As a proactive measure, building services also thoroughly cleaned the 6th-grade section of the building last night; additional cleaning efforts will continue this weekend.”
All other students were dismissed at the regular time. After-school activities continued as planned, as well as the school’s production of “Annie.”
