Another two people have tested positive for COVID-19 at Saint Michael Catholic High School.
But only one them actually attended the school while they were infectious and Public Health is reaching out to their close contacts.
The principal has sent another letter to all staff and students to fill them in on the situation.
Niagara Catholic says the newest cases are not linked to the other two cases that were reported earlier this week.
