So if I have HIV, am I still allowed to go to bars and procure sex, or do I get locked down with police knocking on my door with stay home orders because im infected.
If you sleep with a partner without telling them you are HIV positive, you can be jailed. So yes you can go to bars etc and procure whatever and you must disclose any diseases that could infect them that you are aware of. HIV is only transmitted via blood etc. You can not walk past someone and infect them.
A partner can actually sue you if they can prove you knowingly slept with them knowing you had an STDs. Same way you can be fined or sued for spitting on someone as its known to spread disease of just about anything.
The idea of lockdowns and isolation is to limit the spread opportunity for easily communicable diseases that can transmit easily to unwilling participants.
