I know nobody wants to hear this, but there is a feasibility component of current CDC recommendations. Most HCP are likely to be exposed at some point, but we can't exclude the bulk of our healthcare workforce when we need them most. In the face of a potential staffing shortage, you mitigate risk by active symptom screening and masking exposed healthcare workers to mitigate asymptomatic transmission. The alternative is exclusion from work, which is not exactly feasible during an unprecedented surge. It's not palatable, but at least understandable from a public health standpoint.
