Syphilis stage (number)	Mean age ± SD	Median RPR	Percent taking ART	Median CD4 (cells/mL³)^a	Virologic suppression(< 50 copies/mL³)^a	Median viral load (copies/mL³)^a
Primary (5)	34 ± 10.5	1:16	100%	524	60% (n = 3)	49
Secondary (29)	33 ± 10.4	1:64	48%	336	34% (n = 10)	2235
Early latent (6)	38 ± 10.2	1:64	83%	278	0% (n = 0)	283

CD4 count and viral load ± 180 days from syphilis diagnosis.

SD, standard deviation; RPR, rapid plasma reagin; ART, antiretroviral therapy.
