According to Public Health Scotland today:
28 (0.1%) [Covid cases] were reported as definite hospital onset (first positive specimen date was 15 or more days after admission to NHS board). In the previous week (week ending 27 June 2021) there were 9 (0.05%).
This not a statistically significant change and, as you can see, tiny in the contest of rates early in the year.
Public Health England has solved its hospital onset problems by not reporting them but there are always leaks?
In the first wave when Scotland peaked at 10% NHS England estimated 20-25%:
In the second wave in NHS England, 17.6% of Covid cases were hospital-acquired infections and in the North West, 25%!
