Mandeville and colleagues describe a fascinating case where Facebook was used to warn potential contacts that their acquaintance had a communicable disease (Mandeville et al., 2013). They are correct that this case raises important issues about social media, confidentiality and the prevention of harm. However, they underestimate both the dangers of overcommunication via Wall and Timeline postings (and Twitter) and the potential utility of Facebook in cases like this one. Increased awareness of Facebook functionality will allow more accurate targeting of (...) those at risk of infection, while also protecting the confidentiality of the index case. (shrink)

Public health ethics is a nascent field, emerging over the past decade as an applied field merging concepts of clinical and research ethics. Because the “patient” in public health is the population rather than the individual, existing principles might be weighted differently, or there might be different ethical principles to consider. This paper reviewed the evolution of public health ethics, the use of bioethics as its model, and the proposed frameworks for public health ethics through 2010. Review of 13 major (...) public health ethics frameworks published over the past 15 years yields a wide variety of theoretical approaches, some similar foundational values, and a few similar operating principles. Coming to a consensus on the reach, purpose, and ends of public health is necessary if we are to agree on what ethical underpinnings drive us, what foundational values bring us to these underpinnings, and what operating principles practitioners must implement to make ethical decisions. If public health is distinct enough from clinical medicine to warrant its own set of ethical and philosophical underpinnings, then a decision must be made as to whether a single approach is warranted or we can tolerate a variety of equal but different perspectives.

After arrival in a hospital, a man with suspected meningococcal septicaemia slips into a coma. One of his friends posts a message on the patient’s Facebook ‘wall’ informing three named contacts that the patient has meningitis and tells them to speak to a doctor. At the request of the Health Protection Unit (HPU), this message is later modified, to reduce unnecessary anxiety and to provide better guidance (Mandeville et al., 2013). Based on the harm principle and considerations of reasonableness, it (...) will be argued that in this case the HPU is justified to contact the close contacts of the patient individually (via Facebook or otherwise), and to require the enterprising ‘friend’ of the patient to post a modified message on the patient’s Facebook wall advising close contacts to contact the HPU, without naming close contacts. Generally, the internal logic of social networking sites like Facebook (sharing personal information with a broad range of ‘friends’) is contrary to the logic of health care systems (keeping breaches of confidentiality to a minimum). Social networking sites (SNS) could justifiably be used for contract tracing, provided that such use complies with the well-established norms of health care systems. (shrink)

This article critically engages with Mandeville et al.'s case discussion of using social networking services for the purposes of contact tracing in infectious disease outbreaks. It will be argued that their discussion may be overstating the utility of such approaches, while simultaneously underestimating the ethical concerns that arise from this method of contact tracing. The article separates between ethical and technological concerns and suggests that due to the particular design of networking sites such as Facebook and the usage patterns of (...) subscribers, the positive effect of contact tracing through such services may be overstated. At the same time, using social networking sites raises serious concerns regarding the privacy of patients and the ownership of information posted online. (shrink)
