Hi Yoshii,
Here in the UK we are (so called) ‘living with Covid’.
Hardly anyone wears a mask now as the current variant, for a healthy person who has been vaxinated, is little more than just a cold.
I do see quite a few people with the lingering ‘after Covid’ symptom of persistent cough and runny noise. It can take months for this to clear up and during this period the Covid Flow Test shows negative so I doubt they are infectious to others.
Stay safe my friend,
Tweakie.
