Canada: Twelve latent tuberculosis cases found at Orleans high school

Twelve students at Gisèle-Lalonde High School in Orleans have tested positive for tuberculosis, but all cases are latent and non-infectious, according to public health officials.

Last month, officials from Ottawa Public Health sent a letter to parents saying anyone who attended the French public school between Sept. 15, 2013 and Dec. 24, 2013 may have been exposed.

That’s because two people were found to have contracted TB but did not know they had it at the time they attended school. They may have spread the tuberculosis bacteria.

Students were then tested last week and positive results were expected, officials said.

“Latent TB is not contagious and does not make you sick,” read a statement from Ottawa Public Health, “None of the tested individuals exhibited signs or symptoms of active TB”… (Video at link)
