Do we have a policy for attendance after Covid exposure (not Covid)?

   I did an extra volunteer shift on Tuesday at MGH.  One of my colleagues 
tested positive that night (asymptomatic).  I was masked the whole time I 
was in the building. He wasn't.  My most recent shot was in December. I am 
hoping I am protected enough by my actions and will be testing daily for a 
while to be sure. I was negative today. Short-term question - presuming I 
test negative tomorrow and on the weekend days, do I skip practice on 
Saturday or service ringing on Sunday?  Do we have a general policy based 
on number of negative days since exposure?
