in scotland, it was one in 11 people with the virus, the highest level ever. in england and in wales, it was one in 16. only in northern ireland did cases actually fall, although at one in 17, they're still pretty high. and yet from monday in wales, masks will no longer be the law in shops and on public transport. self—isolation rules will end, too. but with cases of the ba.2 variant of omicron driving this current surge, some safeguards will remain. one of the reasons why the ba.2 variant may have been able to gain a foothold in wales and in the rest of the uk is because of waning immunity, especially amongst the older and the more vulnerable population. and that's why these folk are being urged to grab a jab. this is the spring booster campaign in the suffolk town of newmarket. the nhs in england is under immense pressure, too. but it's scotland which is currently in the deepest crisis.
