HIV transmission rates from persons living with HIV who are aware and unaware of their infection.
Transmission rate modeling estimated secondary infections from those aware and unaware of their HIV infection. An estimated 49% of transmissions were from the 20% of persons living with HIV unaware of their infection. About eight transmissions would be averted per 100 persons newly aware of their infection; with more infections averted the higher the percentage of persons with viral suppression who can be linked to care. Improving all stages of HIV care would substantially reduce transmission rates.
