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

The latest case involves a student 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.

The student is at home and doing well, and the general school population is at low risk of exposure, TCDSB health and safety manager Corrado Maltese said.

Toronto Public Health informed the school board of the case Tuesday afternoon.

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.

Tuberculosis (TB) is caused by a germ called Mycobacterium tuberculosis and it usually infects the lungs, although it can also affect the kidneys, spine and brain.

The main symptoms are a bad cough, fever, weight loss and weakness, the Canadian Lung Association says.

People who are sick with active TB disease spread the germs through the air, and most people catch the contagious disease from an infected person at their home or work.

People with active TB disease can spread the germs in the air by coughing, laughing, sneezing, singing, playing a wind instrument or talking, the Canadian Lung Association says.
