HIV negative people are able to take PrEP, an antiretroviral medicine that stops the virus replicating in the body.Medication has got progressively better, says Hall, whose experience has gone from having to take multiple tablets down to just one a day.
The side effects have also "hugely reduced", he says, and "people like me can't pass on" the virus."Now I'm in a relationship with somebody who's HIV negative and he takes PrEP, I take my medication, and we have unprotected sex, we have sex without a condom.
If I think back to my younger adult years, I can't even imagine this being the case. It's a revelation."As an HIV activist, Hall says he is very aware that his is the "archetypal" story of someone with the virus.
