According to a report by the Institut national de santé publique du Québec (2014), more than 29,000 cases of STBBIs were reported in Quebec in 2014 and they represent 75% of all infections recorded in the database of diseases that must be reported.
- The incidence of reported cases of Chlamydia trachomatis and gonococcal infections is steadily increasing, particularly among young people aged 15 to 24, with the increase more pronounced among young men.
- The resistance of the gonococcus bacterium to antibiotics used to treat this infection poses several challenges, including the ability to track the resistance (and the resulting treatment failures) and propose new treatment regimens in the event that the resistance spreads.
- Almost half (47%) of gonococcal infections in men are only rectal and pharyngeal infections.
- The infectious syphilis epidemic, initially concentrated in the Montreal area, now affects most regions of Quebec. The significant increase observed in recent years now seems to be stabilizing.
- An outbreak of lymphogranuloma venereum has been observed since spring 2013. This increase intensified sharply in 2014 and 2015.
- The incidence rate of reported cases of hepatitis B has stabilized in recent years in Quebec, underscoring the importance of continuing vaccinations against hepatitis B, particularly among people at risk who have not benefitted from a school-based program.
- Approximately 1,100 cases of hepatitis C were reported in 2014, increasing the pool of infected individuals and highlighting the need for access to treatment to prevent liver complications.
- The annual number of new HIV diagnoses is decreasing. An upward trend was observed between 2009 and 2013 among 15- to 24-year-old men who have sex with men (MSM), but this increase did not seem to continue into 2014. This trend should be interpreted with caution, however, due to the small number of cases.
