So far, rehearsal is on tonight for the church I play at this Sunday, and AFAIK, for rehearsal for my home church for Sunday. Most are huggers, and I'll just avoid handshakes and face-licking.
One thing the news media and health organizations don't seem to be saying (at least here) is to remember to keep your immune system as healthy as you can. Exercise, eat well, and take reasonable vitamins and supplements. This can help keep you healthy in case of marginal contact, and reduce the symptoms if you do get sick.
And of course, it lets you play your THUNDERBIRDS mo betta mo longa! At least that's what I hoid on the grapevine while running through the jungle down in the bayou...
