At baseline, Weeks 24 and 48, and then every 48 weeks until study completion, women undergo pelvic examination and cervical specimens collection by the following methods: 1) Sno-strip; 2) cervicovaginal lavage; 3) cervical brush method; and 4) Pap smear. A colposcopy is required for any woman who has an abnormal Pap smear reading unless the abnormal Pap smear is thought to be due to an intercurrent infection. A cervical biopsy is strongly recommended in the event of an abnormal colposcopy. Blood is collected for HPV antibody testing, viral load, and CD4 measures.
