LTC, COVID-19 & Visits

Just wondering if any other LTC nurse's have any input on guidance in regards to out-of-facility visits for the residents and Covid.  It has been said that we can allow out-of-facility visits if they are "low risk" situations, but how are facilities determining that?  Does anyone have some sort of screening tool that they'd be willing to share?  Eager to see our residents doing more and seeing their families more, but want to do so in a safe way.  Thanks in advance!
