Estimated proportion of PLHIV and transmission proportion attributable to PLHIV subgroups in Nigeria, Ethiopia, Rwanda, Lesotho, 2010–2020.

Countries chosen as illustrative examples as their transmission proportion patterns are similar to other countries in their regions. See S12 Fig for all countries in analysis.</p
