I was reading this historical fiction book where one of the character said measures like closing markets/linen cloth to cover face and mouth by nuns who treated the sick and washing hands with vinegar were employed in Florence during the pandemic but they were too late.
That got me thinking whether similar measures were taken in real life when the pandemic hit Europe and what were the measures?
Yes, there were some measures. From what I remember of a talk I heard a couple of years ago during Tudor times for example, households could be quarantined, with only 1/infected household allowed out with 4ft white rods to let others know.
Here's a short blog post from the UK National Archives if you would like a bit more information: https://blog.nationalarchives.gov.uk/shut-up-quarantine-and-social-distancing-during-tudor-epidemics/
Edit: admittedly the famous Black Death as opposed to the plague was during the 14th century not under the Tudors, but it was still basically the same disease, just later
