St. Jerome Elementary School in Riverside South has been closed by COVID-19, according to the Ottawa Catholic School Board (OCSB).
The OCSB announced Thursday night that two staff members at the school had tested positive.
Two schools in Ottawa were closed by an outbreak this week: École Horizon-Jeunesse and École secondaire catholique Franco-Cité.
Neither St. Jerome nor the board has said what kind of virtual learning is being offered. It's not known how long the closure may last.
Ottawa Public Health has active outbreaks in 10 schools, according to its most recent update Thursday. It has not listed St. Jerome yet.
An outbreak is when public health officials have reason to believe the coronavirus spread during a school activity, including on a school bus or during before- or after-school care.
More than 150 schools in the wider Ottawa-Gatineau region have now reported at least one case of COVID-19 since classes resumed.
