Two Patients

You are the primary care physician of a patient with the HIV virus, but no AIDS symptoms. One day you greet him in the waiting room and see another female patient of yours. You are surprised to see her because she does not have an appointment with you that day, but she explains that your male patient is her boyfriend and she drove him to his appointment. You ask him in the examining room if he has notified his girlfriend about the HIV, and he says “no.” Do you notify her?
