Hepatitis C incidence rates have been increasing over the past 5 years between 2009 and 2013 in the NWHU area. In this time span, the rate of Hep C has more than doubled, and the difference is statistically significant. Rates in the province remained relatively stable during this time, while a sharp increase in incidence was seen in 2011 in the NWHU area as well as in 2013. Rates in the NWHU in 2013 were statistically significantly higher than in the province as a whole.
About 59% of cases between 2009 and 2013 were female, and almost two-thirds (64.7%) of the cases were in the 20-44 age group.
Upon further analysis, the increased incidence in the past few years can be largely attributed to increased testing in First Nations communities throughout the region which has resulted in more cases being discovered.
