Association between CVL and HIV transmission for WE and SSA. (A), (B) Incidence (blue), force of infection per year (orange) and CVL measured in HIV RNA copies/mL (black) for WE and SSA. CVL is shown on $lo{g}_{10}$-scale. HIV incidence is shown per 10000 individuals. The force of infection is multiplied by 100 so that it can be shown in the same plot with CVL and incidence. (C), (D) Contributions to the force of infection by unaware, diagnosed untreated and treated individuals. The sum of the three contributions is the total force of infection.
