Pittsburgh Carmalt PreK-8 will be closed Monday for cleaning after an apparent norovirus outbreak among students and staff members.

Pittsburgh Public School District spokeswoman Ebony Pugh said the schools, located in the Brookline neighborhood, have been receiving a “high volume” of reports of non-COVID-related illness from students and staff since Thursday.

The district, in consultation with the Allegheny County Health Department, determined the illness is most likely norovirus.

Norovirus is a virus that is transmitted through contact with stool or vomit and touching contaminated surfaces.

On Monday, the district’s maintenance team will clean the building “thoroughly” in order to prevent further infections.

Classes will resume on Tuesday, Dec. 14.

Common symptoms associated with norovirus include diarrhea, vomiting and stomach pain. A loss of energy, mild headache and low-grade fever are sometimes present, the district said.

There is no specific treatment for norovirus and symptoms usually resolve within 24-48 hours.
