I think I may have had it too.
I stayed in since last Friday up to yesterday, but I had three deliveries. After receiving the second one, I left it in the porch, washed my hands and carried on with my usual activities. The day after I thought I’d better put the delivery away (a big sack of Epsom salts - for my daily baths!) I felt an unusual pin-prick type sensation in the palm of my hand. Washed hands as usual (always do whenever I pick up mail or receive a delivery - even before Coronavirus) but that night I felt a strong urge to rub my eyes as well. I was in the bath so figured clean enough to!
Same and following day I got that sensation you often get at the beginning of a sore throat, a pin prick burning type feeling in the back of my throat on swelling (just once), and then later down my food or wind pipe. I also experienced a few twinges in my chest. Also have a slight feeling similar to the aftermath of having a head-cold. I’ve coughed a few times too - but I am actually pretty good at surprising a cough. No temperature tho.
So I would say it’s possible I have had it, and (so far anyway) there’s been no major or debilitating symptoms… yet.
A friend from the gym (early 20s, in great shape) has got it (now confirmed) and had to go into hospital as he had chest pains on top of a cough. He’s now self-isolating. Just goes to show this can affect anyone of any age.
