A student at Nora Frances Henderson Secondary School tested positive for COVID-19 on Wednesday.

Public health and school administrators have notified anyone identified as a close contact. Students and staff linked to the case will need to self-isolate for 14 days.

"Public health has determined there is no epidemiological link between this and previous cases at our school, and therefore no outbreak will be declared," reads the letter to families from principal Timothy Powell-McBride.

A student at Helen Detwiler was also infected by COVID-19, but was not in the building when they were infectious and had no close contacts within the school.
