Earlier quoted context omitted.
The infecting other people is mostly theoretical. As far as I know there is no actual instance of transmission from a person with an undetectable viral load on antiretroviral drugs to an uninfected person.
> an undetectable viral load on antiretroviral drugs to an uninfected person Can you please put this into simpler terms? I am pretty confused. Because HIV transmission is not a theoretical and is not a myth. My understanding is, OP meant to say "transmission of HIV via known risky activities." --EDIT-- Thank you for those clarifying. Often the unfamiliar technical terms can throw me off.
It's possible, with treatment, for people with HIV to have a viral load labelled undetectable.
To date, from an article I read, there have been no recorded transmissions from people with an undetectable viral load.
