The World Health Organisation says wearing a mask will not protect you. It has to be 3 layers thick and cover the mouth, nose and chin. Hand washing is vital especially when you get home. Most people do not wash and dry their hands properly. It should be done for 20 seconds minimum with soap and hot water starting with the wrists, working your way down in between fingers, backs of hands in hot water. Equally important is thoroughly drying hands. Most do not do anything like that.
So they say
All I know is that 2 sisters in law and I travelled together to the S of France by Eurostar and TGV in August.
A man sitting near me on the €* coughed most of his way to Paris.
I went down with Covid the day before came home, 1 sister in law went down a couple of days after me but the third, who lives in London and always wears a mask on public transport because she has bronchiectasis didn't get it despite proximity on the trains and in cars during most of the week.
Anecdotal, maybe but my experience.
