One of the key elements in letting the Corona Virus stay negative in one’s life (other then hibernating)is not to be with a large group of people in a closed setting for an extended period of time. For even if 99% of the people in such settings are negative one positive can have it slowly spread to others. This includes concerts, theater and even your local Shul’s, Churches or Mosques. Some how these venues either have to reduce the time that individuals spend together at once or provide protective clothing when attending. In terms of religious observance maybe just selecting the pieces that are essential to be done as a group and leave the rest to individual observance will be the key. All I know is until this factor is considered large indoor gatherings won’t be as large anymore.
FOOTNOTE- Of course these venues can also be conducted outside as long as the weather doesn’t become a factor.
