Figure 3. Importance of expanded testing and treatment to impact the global prevalence of HCV infection.

Figure 3

Because the % cured is a function of the distribution of many variables such as genotype, age, and race, the y axis arbitrarily shows the efficacy of treatment, which is increasing but having little impact on the overall burden of disease represented by the total area of the figure. 130–170 million are estimated to have chronic HCV infection, while >185 million were estimated to have HCV antibodies in 200546.
