There are very few masks in Sweden. There has been no lock down and very little signs of a second wave despite testing for all being readily available. Yes higher incidence rates than Norway and Denmark but with schools, shops, restaurants and pubs being open from the start that is to be expected. Off to a ' Reggae Got Soul' night tonight and will be happily be able to drink to 1.00am.
Social distancing is observed without government intervention, businesses remain open and people are happy. If you want to wear a mask it's personal choice.
