Measure
Chembio HIV/Syphilis Rapid POC Test
Chembio HIV/Syphilis rapid POC test: Participants will undergo the Chembio DPP® HIV-Syphilis rapid POC test by fingerstick. The Chembio test is read by a handheld reader. If positive for syphilis, the participant ill be informed and treated at the same visit with intramuscular (IM) Benzathine penicillin G (BPG) according to clinical stage and will undergo point-of-care ultrasound for the detection of fetal markers for congenital syphilis.If positive for HIV, participant will be started on Bictegravir/Tenofovir Alafenamide (TAF)/Emtricitabine (FTC) per guidelines
