if that is the truth Clonadmad, and that is what I am also hearing, then this one fellow should have had the cop on to self isolate. If you are in a potentially hazardous environment, be it home or work, then you have no business getting involved in any multi group setting.
for instance if someone from one of the senior club football panels, has just returned from a holiday in Spain/France/Portugal, then he has no business joining his club squad this weekend.
