Fig. 3. Proportion of transmissions by stage in the infection and care continuum, versus proportion of these stages amongst infected men.
(A) Relative frequency of infection/care stages in the population, among potential transmitters that overlap with the infection windows of recipient MSM and could have in principle transmitted to one of the recipient MSM. (stage A in figure 1, colour codes as in figure 2). (B) Proportion of the 617 transmission events attributable to each infection/care stage (bar: 95% bootstrap confidence interval).
