As I understand it, large studies of couples where one partner has HIV with an undetectable viral load and the other does not have HIV have not recorded any cases of transmission through sexual activity. The question of whether it's "impossible" or "extremely unlikely" comes down more to philosophy than anything pragmatic at this point. Transmission through sharing needles we have less confidence around, because illegal drug use is harder to study. IIRC not everyone reaches an undetectable viral load through antiretroviral medication, so you do need to make sure that's the case. Pre-exposure prophylaxis and general safe sex practices like condoms can mitigate the risk for people with low-but-detectable viral load and their partners. |

When everything seems dark and hopeless, this is one of the examples that always lifts my spirits. Humankind can achieve incredible things together.
