MSM: men who have sex with men; NA: not available; PWID; people who inject drugs; YDF: yearly diagnosed fraction.

a Defined as CD4 < 350 cells/mm3 and CD4 < 200 cells/mm3.

b Data in this table are underestimated, as in the Central area new diagnoses with missing CD4 count was at 60%.

The YDF is expressed as the yearly number of new diagnoses / (yearly number of new diagnoses + estimated number of undiagnosed people living with HIV).
