Residence figures are among adults aged 15–64 years.
Note: mean duration recent infection = 130 days (95% CI 118–142 days); proportion false recent = 0.00; time cutoff = 1 year
RPHIA was designed to estimate incidence of HIV at the national level and in the City of Kigali.
Although incidence was estimated for the other provinces, these estimates should be interpreted with caution.
