some people think 2 weeks isolation will work but only works if you have crovid19 if you isolate thinking you have it you could get it the 1st day after. if you haven't got it and dont want to catch it you need to isolate for about 6 weeks and thats where the bulk buying has come from. asda home delivery have told some of its drivers to just leave the goods at the door and told to knock and leave and some have been asked not to take holidays for the next month or 2.
