I'm volunteering with the local branch of the Medical Reserve Corps- maybe there is a unit in your area? I believe they are nationwide. It helped that I volunteered with them in the past (2017) but it seemed like they were happy to welcome new members (even non-medical like me) to assist in the community response of COVID. I did things like deliver PPE, do grocery runs for elderly, do health screenings at elder care facilities, assist at flu clinics and more.
Do you have a previous relationship with any volunteer organization/ someone who can connect you to one? That might be a good place to start as well
