Fig. 3: Density of Infection (DoI) maps and Epidemic Concentration Curves (ECCs).

DoI maps for a Eswatini, b Malawi, and c Zambia showing the number of PWH/km2. ECCs for d Eswatini, e Malawi, and f Zambia. The red dotted lines denote the minimum DoI that would need to be on treatment to achieve each country’s current treatment coverage (estimated at the time their PHIA data were collected); this corresponds to 13.1 PWH/km2 in Malawi, 5.4 PWH/km2 in Eswatini, and 2.8 PWH/km2 in Zambia.
