but ahead of that, she said that anyone who tests positive with covid should self—isolate. she also disagrees with any sudden change to testing arrangements. she would prefer a slower move to a more targeted approach. here in scotland, you must wear a face covering in indoor public places and also vaccine passports are required in places like nightclubs and other large gatherings. in wales, the rules on self—isolation remain. there is a review due next month, but for now, if you test positive, here, you have to self—isolate for at least five days. that may now cause confusion for people who have to cross the border with england for work. masks remain mandatory in shops abd on public transport and in health care until the end of this month, but the welsh government's biggest concern is that change on testing.
