Classic case of misleading graphics without source.

Title: "Traceable infections outside the home".

Let's see where it comes from.

This is the report.

The pie chart comes from the total row, using the values in brackets (i.e. the last week):

So it does come from the report. But what are "Acute respirtory infection incidents"? (ARI)

They are essentially outbreaks or suspected outbreaks - two people linked to somewhere test positive.

So not "Traceable infections outside the home" at all.

It's likely that the data for ARIs is hugely skewed to schools, care homes and workplaces because people go to the same school, same care home and same worksplace.

They don't have any data that looks appropriate to prove the point that hospitality venues aren't a problem with spreading COVID.
