¹ Data are preliminary and expected to change: 2005 data are expected to change more than 2004 data.

² 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.

³ Rate per 100,000 population based on all reported cases for 2004. Total population includes all provinces/territories except Nunavut (See note 5). Population estimates provided by Statistics Canada. (Source: Statistics Canada, Demography Division, Demographic Estimates Section, July Population Estimates, 2004 revised postcensal).

⁴ Rate for 2005 is calculated by projecting current number of cases to 12 months, then calculating the rate (per 100,000). Population estimates provided by Statistics Canada. (Source: Statistics Canada, Demography Division, Demographic Estimates Section, July Population Estimates, 2005 preliminary postcensal). Population includes all provinces/territories except Nunavut. No adjustment has been made for seasonal variability.

⁵ Total population numbers used to calculate rates include all provinces and territories except for Nunavut, where data were not available.

⁶ Reported cases for Ontario in 2005 are underestimates due to transition in the provincial reporting system. Decreases are likely an artifact of reporting delay, not a true reduction in disease incidence. Canadian cases and rates for 2005 are affected.

⁷ 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.
