Second Medford School Closes as Norovirus Suspected in Rapid Stomach Illness Outbreak

Second Medford School Closes as Norovirus Outbreak suspected

MEDFORD, MA – A second local school has canceled classes this week as administrators battle a stomach-illness outbreak believed to be Norovirus spreading through the community.

St. Joseph School, which serves pre‑K through eighth grade and houses roughly 220 students, reported that about 20% of the student body was absent on Monday. In response,leaders announced closures for Tuesday and Wednesday to allow for deep cleaning and disease containment.

This marks the second time in two weeks that a Medford school has halted in-person instruction amid a suspected Norovirus event. Last week, Roberts Elementary School canceled classes on Thursday and Friday after more than 130 students and staff where absent with vomiting and upset stomachs.

Norovirus is a highly contagious virus that commonly triggers vomiting and diarrhea and can spread rapidly in close settings such as schools. The Centers for Disease Control and Prevention identifies Norovirus as a leading cause of vomiting, diarrhea and foodborne illness in the United States. At St. Joseph, officials said there were no medical records confirming Norovirus, but many students were sent home with symptoms consistent with the illness. The two-day closure was planned to allow for thorough cleaning and sanitization to curb further spread. Classes are expected to resume on Thursday.
