Covid comes to Cartref - or does it?

There are reports that someone who works at Cartref has been confirmed to have Covid-19, with no visible symptoms.
[Edited to add new information] However, someone who works there says that they only know of tests which have turned out to be negative.
We've been fortunate so far in Hay - the epidemic has seemed to be far away - but we all need to be careful, use the hand sanitisers, and wear masks.
I haven't been wearing a mask perhaps as much as I ought to - I'll be trying to do better.
