Schoolchildren are tested for TB infection using the tuberculin skin test. |
Of some 170,000 school children in Saskatchewan, 1346 were surveyed, and a stunning 56.6% were found to be infected with TB. Following the results of this survey, the Canadian Tuberculosis Association provided $1000 to each of the other 8 provinces to undertake similar surveys of their schoolchildren.
