FIG 1.

Patient SC3 HIV viral load and CD4 count at each visit during participation in the WIHS cohort. Sequential study visits occurred about 6 months apart, and blood samples were obtained at each visit. V01 refers to the first visit, V04 to the fourth, etc. Data are missing for unattended visits. HIV sequences could first be amplified from plasma samples obtained at V08 and onwards. However, HIV seroconversion was first appreciated under the WIHS protocol at V10, and viral loads were performed only from this visit on. The patient died after V20.
