Summary of the National Advisory Committee on Sexually Transmitted and Blood-Borne Infections (NAC-STBBI) Statement: Recommendations on Screening for Syphilis in Non-Pregnant Adults and Adolescents.

Background: Sustained and significant increases in Canadian rates of infectious syphilis prompted the National Advisory Committee on Sexually Transmitted and Blood-Borne Infections (NAC-STBBI) to update the existing screening recommendation for non-pregnant adults and adolescents.

Methods: These guidelines were developed following the 2014 World Health Organization Handbook. The research question was: "What is the clinical utility of syphilis screening using risk-based versus population-wide approaches for adolescents and adults?" The evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

Risk of sexual transmission of HIV in the context of viral load suppression.

Background: In 2018, the Public Health Agency of Canada (PHAC) published a systematic review to calculate the risk of sexual transmission of human immunodeficiency virus (HIV) in the context of antiretroviral therapy (ART). In 2022, PHAC commissioned the Canadian Agency for Drugs and Technologies in Health (CADTH) to conduct a rapid review of evidence published since 2017. We undertook a meta-analysis of relevant studies from these two reviews.

Translating evidence into practice with the National Advisory Committee on Sexually Transmitted and Blood-Borne Infections.

For over 30 years, the Government of Canada has developed guidelines on sexually transmitted and blood-borne infections (STBBI) with a group of subject matter experts. This expert group provided advice to the Public Health Agency of Canada (PHAC) from 2004 to 2019; transitioning to the National Advisory Committee on STBBI (NAC-STBBI) in 2019. NAC-STBBI supports PHAC's mandate to prevent and control infectious diseases by providing advice for the development of STBBI guidelines.
