MIL-OSI United Kingdom: expert reaction to ONS data on coronavirus and self-isolation after testing positive in England: 8 March to 13 March 2021


Source: United Kingdom – Executive Government & Departments

The Office for National Statistics (ONS) have released data from the COVID Test Trace Cases Insights Survey on self-isolation after testing positive for COVID-19 between 8 and 13 March 2021.

Prof Robert West, Department of Behavioural Science and Health, UCL, said:

“There are three important reasons to be cautious about these results.  First, the rate of reported self-isolation is much higher than that found in repeated surveys using a different sampling method.  Secondly, the data rely on self-report in circumstances where the pressure to report having self-isolated is very high.  Thirdly, this is a sample of people who have chosen to get tested, and responded to the survey and are therefore likely to be much more compliant and the average person.  I therefore think there is a high risk that the headline figure is a significant overestimate.”
