I had a minor cold (which was little more than 'a bit of a sniffle') last week.
However it did occur to me that a common cold (of whatever severity) is caused by one of four coronaviruses. So, despite rarely going out, always observing social distancing and always wearing a face mask in shops, etc, I've still managed to get infected by a coronavirus. Fortunately it was a virtually harmless one but it has brought home to me how easily coronaviruses can be picked up, making me even more determined to steer clear of the potentially very nasty one that's about!
