How do you know you haven't had it.Both the wife and I had a bad cough for about 3 weeks November/December 2019. We did not sleep well and our appetite was affected. We have been lucky in the fact we have not had Covid.
It was prevalent in the UK in sept 2019. And the symptoms that everyone was displaying at the time all point to covid. The original government leaflet highlighting the main symptoms to look out for were symptomatic of what people were suffering from back then.
