I am completely ready to accept the findings of these, no doubt, carefully managed research cohort studies. The findings across several studies were replicated and are great news and reassuring. There is no wish to restigmatise anyone. Jesus. I recall so clearly how my dear friend didn’t want to tell friends because of fear of rejection.
If there is a ‘political’ aspect, I believe it would be an understandable and laudable desire to perpetuate the message on the importance of getting tested and adhering to the medication regime. This message is vital to reducing transmission rates and I am not trying to take anything away from that message or that goal.
This issue of zero transmission came up in a discussion on informed consent. So, on the one hand, no research deals in absolutes. That language is deliberate to convey this and to convey the parameters of the findings ie using the phrase ‘effectively zero’. This is why the findings state upper 95% CI 0·23 per 100 couple-years of follow-up ie a confidence interval of 95% 0.23 over several years of follow up.
On the other, the HIV medical community may have felt, on balance, population transmission rates will be lower by encouraging people to get tested and stay on the medication and perpetuating the message that there’s no need to inform if risk of transmission is effectively zero. About the latter, I have no knowledge. Is this something explicitly stated by the medical community? Is current advice explicit on ‘no need to inform’ potential partners?
It’s been many many years since I was involved in HIV care and no doubt discussions will have moved on keeping in mind that the medical community is concerned at a population level whereas morality is individualistic ie personal choices about what’s right and wrong. I’m not saying it isn’t difficult to navigate. But agree with @Boiledbeetle that no unprotected sex until tested (after no risk of seroconversion) is the only way to be sure. However, humans being human and complicated, that is never going to be wholly the case. So thank god for ART.
