So, still a crime, even if a misdemeanor? Pretty sure it's still negligence if you actually infect someone, as per your link:

> A defendant might be negligent for infecting a partner with HIV if:

    The defendant knew he or she had AIDS or was HIV-positive;
    The defendant was negligent in not disclosing his/her status and/or not using a condom or dental dam; and
    As a result of that negligence, the plaintiff acquired the disease through the transmission of HIV and suffered damages  (such as medical bills and/or pain and suffering).
