Table 1. Coverage levels for the three scenarios that we modeled.

Parameter estimates for Southwestersn Uganda (SW Uganda) and KwaZulu-Natal (KZN) are separated by commas.

	Coverage Level
	Current	High PMTCT	High ART and PMTCT
PMTCT
PMTCT initiation (weeks)	22, 22	14 [62], 14 [62]	Same as High PMTCT
PMTCT uptake (%)	57 [23], 53 [24]	90, 90 [assumption]	Same as High PMTCT
ART
CD4 count at ART initiation (cells/μl)	131 [26], 100 [63]	131 [26], 100 [26]	350, 350 [assumption]
ART uptake (%)	48 [64], 53 [64]	48 [64], 53 [64]	90, 90 [assumption]
Proportion of those on ART who are virally suppressed (%)	88 [64], 85 [64]	88 [64], 85 [64]	Same as Current
