Tailoring Public Health Policies, Govind Persad

Publications

In an effort to contain the spread of COVID-19, many states and countries have adopted public health restrictions on activities previously considered commonplace: crossing state borders, eating indoors, gathering together, and even leaving one's home. These policies often focus on specific activities or groups, rather than imposing the same limits across the board. In this Article, I consider the law and ethics of these policies, which I call tailored policies.In Part II, I identify two types of tailored policies: activity-based and group-based. Activity-based restrictions respond to differences in the risks and benefits of specific activities, such as walking outdoors and …
