1) the number of averted HIV transmissions is estimated by multiplying the number of persons with HIV who became aware of their status and the difference in transmission rates before and after knowing their HIV status. h = d * [f–g].
2) The average HIV transmission rate for all groups was used for the number of averted transmissions.
