Cutting the Slack or a Chancer's Charter?

Staff absenting themselves for 7 days after a positive Covid test, creates problems in many sectors. This is especially true of medical, teaching and hospitality sectors. The UK's minister has now reduced the 'isolation' to 5 days, when the individual has consecutive negative tests on days 4 and 5. Sally Cutler (University of East London) thinks this is 'foolhardy and dangerous' (https://www.theguardian.com/commentisfree/2022/jan/13/cutting-covid-isolation-period-five-days-foolhardy-dangerous). Cutler notes that many people are at their peak of infectiveness around 3-6 days after going down with Covid19. The original rules specified 10 days after infection, before people were free to mix in society. It will be interesting to see whether the reduction to 5 days actually results in a sustainable increase in the availability of 'key workers'. It's also surely not unreasonable to suggest that some 'key workers' are more 'key' than others? Health and education surely trump serving drinks in bars?
