SECONDARY outcome

Timeframe: HIV diagnosis visit

HIV present in blood samples from recently infected study participants was sequenced. Sequences that were similar to each other were grouped together in clusters. For this analysis, clusters were defined using a patristic distance threshold of 0.01, and a minimum cluster size of two.

SECONDARY outcome

Timeframe: HIV diagnosis visit

Population: Analysis population is limited to HIV-infected participants for whom HIV sequence data are available. Per initial protocol design, this analysis was conducted on all HIV sequences without dividing by randomization arm.

HIV present in blood samples from recently infected study participants was sequenced. Sequences that were similar to each other were grouped together in clusters. For this analysis, clusters were defined using a patristic distance threshold of 0.01, and a minimum cluster size of two.

SECONDARY outcome

Timeframe: within 3 months of diagnosis of acute HIV infection

Population: Analysis population includes only those participants whose HIV infection was diagnosed during the acute phase, that is prior to HIV seroconversion.

To determine the proportion of individuals with evidence of acute infection (HIV-1 RNA-positive) who are successfully contacted for confirmatory HIV testing and are then linked to care.
