The standard for criminal HIV transmission (in California, at least; it varies by state) is not "accidentally infecting someone while not knowing your status."

The standard for criminal HIV transmission (in California, at least; it varies by state) is not "accidentally infecting someone while not knowing your status." It's not even "infecting someone without disclosing that you're HIV-positive while knowing you're HIV-positive." It's "intentionally infecting someone with HIV." And, explicitly, your knowledge of your positive status is not sufficient to establish intent.
