“A principle in COVID-19 is to provide as much pastoral care by telephone as possible, or other non face-to-face means, as a means of reducing the spread of the virus.”
A priest having face to face meetings with multiple sick people has the danger of spreading the coronavirus, especially if they were to touch those who are sick.
I know of at least 2 diocesan bishops (and I know there are more) who have put put together a Last Rites team of priests who are non-elderly, non-risk-burdened, equipped with PPE, and pre-trained in the protocols of nursing homes and hospitals.
Well, if physical danger is your primary concern, the safest option would be to immediately give the hospitalized victims lethal injections and then incinerating their corpses.
