I recovered from Covid about two weeks back. I wouldn't describe it as unusually mild, it was easily as severe as my worst dose of flu in the UK. Temperature, headache, sore throat, raking cough, shortness of breath and aching joints. Laid me out for about 10 days, wasn't able to do any work around the house. Was either laid on the bed trying to read, or sitting at my computer (didn't have much enthusiasm to do either). Never been so pleased to see the back of an illness.
I don't know how long my natural immunity will last, but I'll certainly be looking to have a jab at the start of the next wet season. I wouldn't like to have to go through the experience again.
