Two public schools in Wellesley, Massachusetts, were dismissed early on Friday after a parent reportedly tested positive for the coronavirus.
Upham Elementary School and Wellesley Middle School were the two schools dismissed at 11:45 a.m.
"We learned a short while ago that a Wellesley resident has tested positive for COVID-19," the school said in an email to parents. "This individual is a parent of children who attend the Upham Elementary School and Wellesley Middle School."
The school district said the children are showing no symptoms and are healthy.
"Out of an abundance of caution, we have made the proactive decision to release students early at Upham and WMS in order to fully clean and sanitize both buildings," the district's statement said.
All other Wellesley Public Schools will complete their day on a regular schedule.
