To inform efforts to maximize HCV screening coverage, our objective was to identify demographic groups reporting a lack of HCV awareness, particularly by race/ethnicity and age, and sources of health information. We used nationally-representative data of adults (≥18 years) included in the 2019 Health Information National Trends Survey (N = 5438). Awareness of HCV was defined using the following question "Have you ever heard of the Hepatitis C virus (also known as Hep C or HCV)?" We estimated frequencies by demographic groups and computed risk differences (RD) with 95% confidence intervals (CIs) to compare lack of HCV awareness by age (<55 and ≥ 55 years) and race/ethnicity. Overall, 17% of adults never heard of HCV. Younger adults <55 years(21%) were more likely to have never heard of HCV compotentially through social media campaigns. Reported cases of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections are increasing among Canadian men. Estimates of community-based CT/NG prevalence are lacking among gay, bisexual and other men who have sex with men (GBM). Respondent driven sampling was used to recruit GBM in Montréal, Canada between February 2017 and June 2018. Specimens provided from urogenital, rectal and pharyngeal sites were analyzed using nucleic acid amplification test (NAAT) to detect CT/NG. Prevalence estimates of CT/NG, overall and by anatomical site were calculated. All estimates are RDS-adjusted. Among 1177 GBM, the prevalence of rectal, urogenital, pharyngeal and overall were respectively 2.4%, 0.4%, 0.4% and 2.8% for CT infections, and 3.1%, 0.4%, 3.5% and 5.6% for NG infections. If testing had been limited to the urogenital site, 80% and 94% of CT
