This [1] is a useful summary of statistics comparing the current situation to that of Spring and earlier years. It’s interesting to see that the total number of hospitalised people and deaths are broadly in line with previous years, but the portion tagged as COVID is increasing. There’s lots of discussion around the issues with PCR testing (e.g. picking up old virus fragments & false positives). Difficult to know what to believe but there seems to be a lack of studies/data to back up the accuracy, and the NHS have recently switched to using Lateral Flow devices for regular staff testing due to the volume of asymptomatic staff being require to isolate.
