WINDSOR, ONT. -- The entire school community at WJ Langlois Catholic Elementary School in Windsor is now being sent home.

Originally there were two confirmed COVID-19 cases in a classroom and the cohort was dismissed, but the Windsor-Essex County Health Unit says there are now four confirmed cases in the school.

The outbreak has forced a full school closure.

The entire school is considered "high risk" and officials are directing staff and students to isolate for 14 days and self-monitor for symptoms.

“It is essential for students and staff of W J Langlois to self-monitor for COVID-19 symptoms every day. If you have any symptoms, go get tested,” says Dr. Wajid Ahmed, medical officer of health with WECHU.
