if you have sex while you know you have a STD, it’s a misdeameanor in most states. I doubt you can be prosecuted outside the US for that kind of things. If the disease can cause death (such as HIV or hepatitis B) it may be considered a felony (in the US and in most Western countries).
It varies a lot between states. In Illinois, only HIV is prosecuted. In Texas, knowingly transmitting gonorrha is considered assault and is either a a misdemeanor or a felony.
