Which ethical considerations apply to public health surveillance and outbreak investigations, particularly regarding confidentiality?

• A. Respect for persons, beneficence, justice; protect confidentiality by minimizing data collection, de-identifying data, limiting access, and secure storage; informed consent is often not required for routine surveillance.
• B. Respect for persons, beneficence, justice; protect confidentiality by sharing data openly when possible; informed consent is always required.
• C. Confidentiality is optional and not usually enforced in surveillance.
• D. Informed consent is always required for routine surveillance.

Answer: (A)

In public health surveillance and outbreak investigations, the main goal is to protect people while gathering enough information to prevent harm, guided by respect for persons, beneficence, and justice. To protect confidentiality, the approach is to collect only what’s necessary, de-identify data when possible, restrict access to authorized individuals, and store information securely. For routine surveillance, informed consent is often not required because the data collection serves the community and is supported by public health authorities with built-in safeguards. Openly sharing data or requiring consent in all cases would undermine privacy and the practical realities of routine surveillance, so those practices are not consistent with standard ethical practice.
