Participant-reported count of total number of CLAI acts with any non-main partner (insertive or receptive) in the 30 days before the visit. See STAR methods for rationale and details.
EDDI, or Estimated Date of Detectable Infection, is calculated from a published calculator that uses all available HIV test results and methods to calculate the most probable date of HIV acquisition, including uncertainty estimates for First Possible and Last Possible Date of Infection.
