Would someone in this scenario be liable? I just want to first say that this isn't me by any means, I would never do such a scummy thing.
One of my workmates and close friends told me that she found out her husband was cheating on her. She also suspect he might have done it when he was abroad in SE Asia. She's gotten tested and thankfully come back as negative for all STD's.
Knowing the rate of HIV in SE Asia, if he had contracted HIV and passed it on to her, would he be criminally responsible? I know in the UK and US, it can only happen if there is proof that the person had unprotected sex knowing that they were positive.
I do find it interesting how many people cheat but we rarely hear about incurable STD's being passed on.
