A patient tests positive for HIV test. They have requested the test, but then decided that they didn’t want to know the results, Should the person be told anyway? Should the risk to others be considered in the decision whether to inform them against their will? Do you have an obligation to tell them or to tell their loved ones? If the person refuses information, is it a breech of confidentiality if sexual partners are informed? Explain your reasoning.
