HIV, a Pregnant Wife, and the Limits of Confidentiality
Mr Wong, 34, an accountant, was diagnosed with HIV six weeks ago after a routine insurance test. His CD4 count is 160 cells/µL and viral load 120,000 copies/mL. He has not started antiretroviral therapy. He has been married for six years and has a 3-year-old son; his wife is 10 weeks pregnant with their second child. He has not told her his diagnosis. He says they have sex 'once or twice a month, usually with a condom, but not always'. He begs you not to tell her: 'She will divorce me and take the children. I will lose everything.' He agrees to start treatment and says he will 'deal with it in his own time'. A nurse in your clinic knows his wife socially. He asks you to record in the notes only that he has a 'chronic viral infection'.
1. What are your professional obligations regarding confidentiality and the risk to his wife?
Read the worked answer
Confidentiality is a fundamental professional duty, but it is not absolute. Under the Medical Council of Hong Kong's guidance, disclosure without consent may be justified where there is a serious and identifiable risk to a specific person, the risk cannot be eliminated by less intrusive means, and the public interest in disclosure outweighs the patient's interest in privacy. Here the wife is identifiable, HIV is a serious condition, transmission is preventable, and she is pregnant, which raises the stakes for her and the fetus. However, the first obligation is to work with Mr Wong to enable him to disclose. You should not promise unconditional secrecy. Explain the limits of confidentiality at the outset, explore his fears, correct misconceptions about transmission and treatment, and emphasise that starting antiretroviral therapy will reduce risk but does not eliminate it immediately. The nurse who knows his wife must be reminded of her own confidentiality obligations and excluded from his care if there is a conflict of interest. Record the discussion, but do not falsify the diagnosis in the notes.
2. Outline the steps you would take before considering disclosure without consent.

First, discuss the situation fully with Mr Wong: the risk to his wife, the importance of her knowing so she can be tested and, if positive, treated; the risk to the pregnancy; and the practical consequences he fears. Offer to help him tell her, or to have a counsellor or social worker support a joint disclosure. Offer partner notification services, including the option of provider-assisted notification, and clarify what would be disclosed and by whom. Address his fear of divorce and loss of contact with his children, and consider involving a medical social worker for financial and legal concerns. Give him a clear but reasonable timeframe to disclose, for example one to two weeks, and arrange follow-up. Start antiretroviral therapy promptly to benefit his own health and reduce transmission risk. Document the counselling, his refusal, and the agreed plan. Seek advice from your hospital's ethics committee or legal team before any disclosure. Only if he still refuses, and the risk remains serious and imminent, should you consider disclosing the minimum necessary information to the wife.
3. If he continues to refuse, may you disclose? If so, to whom and how much?

Yes, disclosure without consent may be justified in these limited circumstances, but it should be the last resort. The person to inform is the wife, because she is the identifiable person at risk. Disclose only the minimum necessary: that she may have been exposed to HIV and should seek testing and counselling, without revealing unnecessary details about her husband's health or lifestyle. Ideally, tell Mr Wong first what you intend to do, when, and why, so that he is not blindsided and can prepare. Do not disclose to his employer, friends, or extended family. Record the rationale: the nature of the risk, the attempts to persuade him, the advice sought, and exactly what was disclosed. Continue to support him and offer to help him tell her himself. If he threatens self-harm or violence, address that separately. The aim is to protect the wife's health while preserving as much of Mr Wong's confidentiality and trust as possible.
