The latest session-approved version of the Covid-19 mitigation plan adopts CDC guidance on modifying precautions based on levels of community transmission.  If the level is substantial or high, the CDC -and this plan- recommends mask wear and social distancing by all congregants.  If the level is low or moderate, mask wear and social distancing will be optional for vaccinated and recommended for unvaccinated and immunocompromised.  The level of community transmission will be posted by the entrance.
