1 The term STI (Sexually Transmitted Infection) is now commonly used in place of STD (Sexually Transmitted Disease). STI is more encompassing, including infections that may be asymptomatic.
2 Data are preliminary and expected to change: 2008 data are expected to change more than 2007 data.
3 Rate (per 100,000) based on all reported cases for 2007. Population estimates provided by Statistics Canada. (Source: Statistics Canada, Demography Division, Demographic Estimates Section, July Population Estimates, 2007 preliminary postcensal estimates).
4 Rate for 2008 is calculated by projecting the cumulative number of cases reported between January 1 and June 30 and then calculating the rate (per 100,000). Population estimates provided by Statistics Canada. (Source: Statistics Canada, Demography Division, Demographic Estimates Section, July Population Estimates, 2007 preliminary postcensal estimates). No adjustment has been made for seasonal variability.
5 Prior to June 2007, Cadham Provincial Laboratory used a non-amplified nucleic acid test for swab specimens and a nucleic acid amplified test (NAAT) for urine specimens to test for chlamydia and gonorrhea. From late June 2007 to September 2007, a new NAAT assay was phased in for swab and urine specimens. The spike in the proportion of tests positive for Chlamydia trachomatis observed during this time is consistent with the sensitivity and specificity of the new test.
6 Infectious syphilis: primary, secondary and early latent stages.
Note: Small variability may exist between data reported by the provinces/territories and the Public Health Agency of Canada. Provincial/territorial data are definitive should a discrepancy exist.
