Public health officials are reporting another case of tuberculosis involving someone at a Toronto high school.

The latest case involves someone at Chaminade College School, an all-boys Catholic school near Jane Street and Highway 400, officials with the Toronto Catholic District School Board confirmed Wednesday.

It is not known if the person is a student or staff member.

The person is at home and doing well, and the general school population is at low risk of exposure, CTV Toronto’s Naomi Parness reported.

Toronto Public Health informed the school board of the case Wednesday morning.

As a precaution, Chaminade College School is doing extra cleaning of surfaces, alerting people who may have had contact with the person, and sending a letter home with students.

In late September, a person at Mary Ward Catholic Secondary School in Scarborough was diagnosed with tuberculosis.

Health officials don’t believe the two cases are linked.
