I had a hacking dry cough - especially at night - for our entire three week stay in Italy over Christmas and New Year 2019/20. It was so bad that, after two nights, my wife banished me to the spare room for the rest of our stay, to enable her to get some sleep. After a couple of weeks with no let-up, I went to see the village doctor, who diagnosed acute bronchitis and prescribed a week's worth of strong antibiotics.....after which it cleared up. However, we now know that Covid-19 was already circulating in Italy at that time and I've never before had a bronchial cough that doesn't produce phlegm. I didn't have any of the other classic Covid symptoms and never got around to having an antibody test, so I suppose that I'll never know for certain. One thing's for sure, however, is that common colds and 'flu seem to have been almost eradicated in our part of the world since the first lockdown....presumably as a result of much improved hand hygene and a lack of hugging and kissing.
