Is there any evidence that Tier 3 lockdowns work I haven’t seen any figures from Liverpool or Lancashire that show what impact the tightening of restrictions have had on the spread of the virus, and what’s the road map to ease those restrictions without reverting to increasing the infection rate ? What is happening in cities and areas that are still in Tier 1, what are they doing differently that’s controlling the spread of infection ? are the differences environmental, cultural, social or are there better controls in place ? Has the wearing of masks made a difference ?
