Background: The Global Viral Hepatitis Strategy aims to eliminate hepatitis as a public health threat by 2030. The hepatitis C virus (HCV) can be difficult to detect as infection can remain asymptomatic for decades. Individuals are often neither offered nor seek testing until symptoms develop. This highlights the importance of increasing awareness and knowledge among health care providers and the public to reach the viral hepatitis goals.

Objectives: To conduct a scoping review to characterize current awareness and knowledge among health care providers and the public regarding HCV infection, transmission, prevention and treatment and to identify knowledge gaps that public health action could address.

Methods: A literature search was conducted using Embase, Medline and Scopus to find studies published between January 2012 and July 2017. A search for grey literature was also undertaken. The following data were extracted: author, year of publication, study design, population, setting, country, method of data collection, and knowledge and awareness outcomes. Commentaries, letters to the editor and narrative reviews were excluded.

Results: Nineteen studies were included in this review. The definition of awareness and knowledge varied across studies; at times, these terms were used interchangeably. Health care providers identified injection drug use or blood transfusions as routes of HCV transmission more frequently than other routes of transmission such as tattooing with unsterile equipment and sexual transmission. Among the general public, misconceptions about HCV included believing that kissing and casual contact were routes of HCV transmission and that a vaccine to prevent HCV was available. Overall, there was a lack of data on other high-risk populations (e.g., Indigenous, incarcerated).

Conclusion: Continued public and professional education campaigns about HCV could help support HCV risk-based screening and testing. Future research could assess the awareness of other populations at increased risk and include consistent definitions of awareness and knowledge.

Conflict of interest: None.
