HIV transmission rates from persons living with HIV who are aware and unaware of their infection

AIDS. 2012 Apr 24;26(7):893-6. doi: 10.1097/QAD.0b013e328351f73f.


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.
