Hopefully it will be just a cold Jerry - there are apparently a lot about at the moment.
My sister was badly last week & was convinced that she had contracated the Chinapox, as others at her workplace had had it. Didn't believe the first negative test as she was getting no better, so had another. Still negative - so "just" a bad cold.
I was the same last Xmas - as Mrs B cares for her vulnerable 90+ year old mother I was sent to be tested when I got symptoms & it came back negative - just the cold I told her I had.
