Impact of the COVID-19 pandemic on reported hepatitis C case counts and rates in 2020
The COVID-19 pandemic reduced the demand for and access to services related to sexually transmitted and blood-borne infections, including harm reduction and testingFootnote 1. This likely impacted new hepatitis C diagnosis rates in 2020, by artificially reducing them. As parts of the country experienced different levels of disruptions due to COVID-19 during 2020, comparisons of hepatitis C case counts and rates between the provinces and territories may also be inaccurate.
Hepatitis C
Figure 1 shows the number and rates of reported hepatitis C from 2011 to 2020. The trends in this figure are described below:
- In 2020, a total of 6,736 cases of hepatitis C (acute, chronic, and unspecified combined) were reported from 12 provinces and territories, for a rate of 18.4 cases per 100,000 people. Of these, there were:
- 186 reported acute cases from sixFootnote 2 provinces and territories for a rate of 1.0 cases per 100,000 people
- 2,012 reported chronic cases from fiveFootnote 3 provinces and territories for a rate of 18.6 cases per 100,000 people
- 4,538 reported unspecified cases from tenFootnote 4 provinces and territories for a rate of 14.4 cases per 100,0000 people
- From 2011 to 2018, total reported hepatitis C rates increased slightly
- From 2018 to 2019, the total reported hepatitis C rate decreased by 9.9%. Whether this decrease observed in 2019 represents a trend remains to be confirmed.
- From 2019 to 2020, the total reported hepatitis C rate dropped by 39.9%
Note: Hepatitis C reporting differed by province and territory from 2011 to 2020. See Appendix B for provincial and territorial hepatitis C reporting patterns.
Hepatitis C by sex and age group
Figure 1 shows the number and rates of reported hepatitis C from 2011 to 2020 and Table 3 summarizes the number of cases, rates, and proportions of hepatitis C by sex and age group reported in 2020. The trends in this figure and in this table are described below:
- In 2020, 62.3% of reported hepatitis C cases were male
- In 2020, the rate of reported hepatitis C among males was 22.9 cases per 100,000 males, and the rate among females was 13.7 cases per 100,000 females
- In 2020, among males, those aged 30 to 39 years had the highest reported hepatitis C rate at 43.1 cases per 100,000 males 30 to 39 years old
- In 2020, among females, those aged 25 to 29 years had the highest reported hepatitis C rate at 32.3 cases per 100,000 females 25 to 29 years old

- In 2020, among females, the largest proportion of reported cases was among females aged 40 to 59 years (27.8%)
- From 2011 to 2020, reported hepatitis C rates were higher among males than females
- Among males:
- from 2011 to 2014, rates of reported hepatitis C fluctuated but were stable overall

The ‘total’ case count and rate include all males, females and those who did not disclose their sex (unknown sex). |
Hepatitis C by province and territory
In 2020, the national reported hepatitis C rate was 18.4 cases per 100,000 people. Provinces and territories that had rates of reported hepatitis C above the national rate included:
- Saskatchewan (38.5 cases per 100,000 population)
- British Columbia (27.8 cases per 100,000 population)
- Yukon Territory (26.1 cases per 100,000 population)Footnote 5
- Newfoundland and Labrador (26.0 cases per 100,000 population)Footnote 5
- Nova Scotia (25.2 cases per 100,000 population)Footnote 5
- New Brunswick (23.9 cases per 100,000 population)Footnote 5
- Prince Edward Island (19.9 cases per 100,000 population)Footnote 5
- Ontario (19.2 cases per 100,000 population)
In 2020, provinces and territories with rates of reported hepatitis C below the national rate included:
- Alberta (13.6 cases per 100,000 population)
- Quebec (9.2 cases per 100,000 population)
- Nunavut (DS cases per 100,000 population)
- Northwest Territories (DS cases per 100,000 population)
DS: Data not shown where case counts are between one and four, inclusive.
In 2020, Manitoba did not provide hepatitis C surveillance data.
- In 2020, the greatest proportion of reported hepatitis C cases came from Ontario (42.1%), followed by British Columbia (21.3%) and Quebec (11.8%)
Acute hepatitis C in Canada, 2020
- In 2020, 186 cases of acute hepatitis C were reported by six provinces and territories (British Columbia, Alberta, Saskatchewan, Quebec, Nunavut, and Yukon Territories) for a rate of 1.0 case per 100,000 people
- In 2020, individuals aged 25 to 29 years had the highest reported acute hepatitis rate C rate (2.8 cases per 100,000 25 to 29-year-olds), followed by individuals aged 30 to 39 years (2.5 cases per 100,000 30 to 39-year-olds)
- In 2020, the largest proportion of reported acute hepatitis C cases was among people aged 30 to 39 years (37.1%)
Acute hepatitis C by sex and age group, 2020
- In 2020, 58.7% of reported acute hepatitis C cases were male
- In 2020, the rate of reported acute hepatitis C among males was 1.1 cases per 100,000 males and among females was 0.8 cases per 100,000 females
- In 2020, among males, those aged 30 to 39 years had the highest reported acute hepatitis C rate (3.1 cases per 100,000 males 30 to 39 years old)
- In 2020, among females, those aged 25 to 29 years had the highest reported acute hepatitis C rate (3.1 cases per 100,000 females 25 to 29 years old)
- In 2020, among males, the largest proportion of reported acute hepatitis C cases was among 30 to 39-year-old males (40.7%)
- In 2020, among females, the largest proportion of reported acute hepatitis C cases was among 30 to 39-year-old females (31.6%)
Hepatitis C continues to be a public health concern
- In 2019, it was estimated that one in four people in Canada who ever had hepatitis C were not aware of their current or past infection and could benefit from testingFootnote 6
- Hepatitis C disproportionately affects certain populations and communities in Canada, including people who inject drugs; people who are incarcerated; First Nations, Inuit, and Métis people; gay, bisexual, and other men who have sex with men; immigrant populations; and the 1945-1975 birth cohortFootnote 7
- Hepatitis C is curable
- Early diagnosis and treatment leads to better health outcomes

Notes
Observed differences in the data published here and the data published in provincial and territorial surveillance products may be due to reporting delays, differences in the date data were extracted from the provincial and territorial surveillance databases or other reporting variations. Where such differences are noted, it is recommended that data and results from provincial and territorial products be used.
