A 43-year-old client comes to the clinic with her partner for a series of fertility tests. The client’s partner used to be the midwife’s patient from another facility, and the midwife is certain that he tested positive for HIV. The client is unaware of her partner’s diagnosis. The midwife talks to the partner in private, and, although he acknowledges that that he used to be her patient, he denies that he tested positive for HIV and refuses to talk to his partener about his diagnosis. What should the midwife’s next action be?
