If penitent is CONFIRMED OR SUSPECTED COVID+ and is self-isolating at home or hospitalized

Given the Catholic Church’s norms for confession:

the priest must be physically present to the penitent in person, and must be able to hear the penitent without the aid of electronic devices (that is, independently of a wired phone, a mobile phone, an intercom, or other audio or video transmitting device).
Amplification of natural sound is permitted (e.g., the priest or penitent uses a hearing aid) but only if the natural sound also reaches the ear.
As always, the priest should take great care to ensure that the conversation with the penitent remains ABSOLUTELY CONFIDENTIAL.

If the penitent is a minor or vulnerable adult, the parent or guardian must be within the line of sight of the child/vulnerable adult and priest at all times.
