Supermarkets, markets, public transport and shopping malls require everyone to wear a mask here in Versailles. Make your own material one or those the local town hall gives out, which can be washed or disposable ones. They don’t stop you catching the the virus but helps to contain it if you an unaware carrier. Medical ones can be given free of charge with a certificate which help to stop the virus entering your body. Sadly those under 35 seem not to wear any in the street, as the are not worried, therefore older people like me have to cross the road to avoid them Under 11s do not wear them to school but older ones do. We are Also asked to use the gel provided at each shop / market entrance. Of course you would not wear any if there were no people nearby
