This is the dashboard report on STI and HIV trends in BC for the third quarter of 2016 (July – September). These reports are posted quarterly to provide a snapshot of HIV and sexually transmitted infections in British Columbia.
The dashboard below describes the number of HIV and STI cases reported to public health in the third quarter (Q3) of 2016. The risk factor categories for HIV — MSM, PWID, and HET — are from the first quarter (Q1) of 2016 due to expected reporting delays.
There were 75 new diagnoses of HIV in BC in 2016 Q1-3, which is slightly higher than this time last year. However, it is in keeping with the previous 4 years. The greatest increase in new HIV diagnoses was among females, though the numbers are small.
There was a 6% increase in chlamydia cases reported in BC for 2016 Q1-3 compared with 2015 Q1-3. This is consistent with the average year-to-year increase in chlamydia cases over the past decade.
There was a small increase in gonorrhea cases reported in BC this year-to-date compared with last year-to-date.
There were 581 cases of infectious syphilis reported in BC for 2016 Q1-3, which is about 10% higher than 2015 Q1-3. However, if this trend continues, we anticipate a similar number of infectious syphilis cases in 2016 compared to 2015. This is because there was a substantial increase in infectious syphilis cases reported in the last quarter of 2015.
Gay, bisexual, and other men who have sex with men continue to be the group most affected by infectious syphilis. There has been a rise in infectious syphilis cases reported among heterosexual individuals, although the numbers are small.
