Communicable Disease Report 2002 - Focus on Tuberculosis - Chapter One
- In 1998, the age-standardized incidence of tuberculosis (TB) per 100,000 population was higher in Peel (9.6) than Ontario (6.5) and Canada (5.9).
- In Peel between 1982 and 2001, the number of cases of TB almost doubled (48 to 90 cases), largely due to population growth.
- In Peel from 1992 to 2001, the highest incidence of TB was found in those over 60 years of age. The incidence of TB in men and women in Peel was similar over this same period.
- In Peel from 1992 to 2001, most cases of TB were in foreign-born individuals (range 89 to 97%). The majority of these cases were from three TB-endemic countries: India (31%), the Philippines (14%) and Vietnam (13%).
- The lungs were the predominant site affected by TB in individuals in both Peel and Ontario.
- In Peel from 1992 to 2001, 10% of TB cases tested were resistant to drugs.
- 73% were resistant to isoniazid alone or in combination with another drug
- 7% were multi-drug resistant (resistant to at least isoniazid and rifampin)
- The proportion of drug resistant TB cases was higher among foreign-born individuals than in those born in Canada.
