Introduction

To facilitate an earlier release of Tuberculosis in Canada, 2008, 5 tables have been extracted from the Canadian Tuberculosis Reporting System (CTBRS) for the year 2008. Data included in this pre-release report should be considered provisional until publication of the full report, Tuberculosis in Canada 2008

Highlights

In total, 1,600 new active and re-treatment tuberculosis (TB) cases (a rate of 4.8 per 100,000 population) were reported to the CTBRS in 2008. These preliminary data suggest that, relative to 2007, the number of cases reported increased by 1.5% from 1,577 to 1,600. The TB case rate in 2008 remained unchanged at 4.8 per 100,000 from that reported in 2007.

The three most populous provinces (British Columbia, Ontario and Quebec) which collectively made up 75% of Canada’s population in 2008, accounted for 69% of the total number of reported cases. The highest rate, 184.4 cases per 100,000 population was reported in Nunavut. For New Brunswick and Nova Scotia the rate was less than 1 per 100,000 population. For Prince Edward Island, no TB cases were reported in 2008.

Individuals between the ages of 25 and 34 years made up the largest number of reported cases, accounting for 18% of the total. However, the corresponding case rate of 6.5 per 100,000 for this age group was surpassed by the age-specific rate 9.1 per 100,000 for those greater than 74 years of age.

In 2008, foreign-born individuals accounted for 62% of all reported TB cases in Canada. Canadian-born non-Aboriginal and Canadian-born Aboriginal cases made up 13% and 21% of all reported cases, respectively.  However, the TB rate in the Canadian-born Aboriginal group continues to be the highest of the three groups, being almost 6 times greater than the overall Canadian rate.

Pulmonary TB, defined as tuberculosis of the lungs and conducting airways, was the most frequently reported main diagnostic site, representing 68% of all reported cases in 2008.  There were a total of 58 cases of primary TB with 66% of these reported in the Canadian-born Aboriginal population.  Of the 174 peripheral lymph node TB cases, 83% were diagnosed in foreign-born individuals.
