I will agree that there are some cases which involve the most draconian impact on Poz Guys are in in need of review. I am not in support of a general repeal of these type of laws when they're constructed in a manner that does not place all HIV Poz guys without any legal protection even when they have done everything in their power to be non-infectious.
i will never agree that when their is an infection of which it is well established can be checked if it is same strain, that anything less than jail is appropriate. Health Authorities need to prioritize public health over the rights of HIV poz men to have sex. I have become aware that in some countries, sexual health advise borders on negligence because they advocate to strongly for Poz mens sex rights which is worthy of support provided they remain legally responsible for transmission. There is no evidence that men will not test because of laws requiring disclosure. Poz men, most of whom would do all they could to not infect others, need not fear legal protection for HIV neg men from those Poz men in the minority who's behavior endangers the sexual health of others.
The plain facts are that free/affordable and confidential testing being available and affordable follow up treatment with the aim of a UVL is what encourages greater numbers being tested. Those men who would avoid testing due to laws requiring disclosure and an onus to be responsible for any infection of others, will not get tested anyway face up to the reality. Those are the very same guys who have multiple other issues and are most likely to suffer medical issues which will provide an opportunity for medical assessment including HIV test of which hospitals who suspect should have the power to do so without consent. The person can then be informed and if they continue to ignore their responsibility to not infect others, take away their freedom.
We shouldn't fear HIV poz men in general at all but that doesn't excuse them from acknowledging they have a responsibility to not infect others or HIV will cease to be a manageable disease and become an epidemic once again. Prep and UVL are great tools but should never become legal defences, if infection happens despite that proper care has not been exercised so full force of the law is appropriate. My public health vs Poz gusy sex rights, hmmmmm, I wonder which is more important to you huh
