Felony
Any person who exposes another to HIV by engaging in unprotected sexual activity (anal or vaginal intercourse without a condom) when the infected person knows at the time of the unprotected sex that he or she is infected with HIV, has not disclosed his or her HIV-positive status, and acts with the specific intent to infect the other person with HIV, is guilty of a felony.
