Understanding Ethical and Legal Obligations in a Pandemic: A Taxonomy of "Duty" for Health Practitioners.

From the ethics perspective, "duty of care" is a difficult and contested term, fraught with misconceptions and apparent misappropriations. However, it is a term that clinicians use frequently as they navigate COVID-19, somehow core to their understanding of themselves and their obligations, but with uncertainty as to how to translate or operationalize this in the context of a pandemic. This paper explores the "duty of care" from a legal perspective, distinguishes it from broader notions of duty on professional and personal levels, and proposes a working taxonomy for practitioners to better understand the concept of "duty" in their response to COVID-19.
