A new interactive map shows which regions in England could have had the most Covid cases. 

Data from the Office of National Statistics studied antibodies which suggested people could have had Covid in the past. 

In England, an estimated one in eight people would have tested positive for antibodies against SARS-CoV-2 on a blood test in December.

It estimated that 5.4 million people in England aged 16 and over could have had the Covid-19 infection.

The South West is the lowest region in England with only 4.9 per cent of the population estimated to have tested positive for the antibodies. 

The highest region was Yorkshire and The Humber with 16.8 per cent. 

The report from the ONS says: "The analysis uses data taken from December 2020 to produce weighted antibodies estimates.

"There is substantial variation in antibody positivity between regions, from 16.8% (95% confidence interval: 14.5% to 19.3%) in Yorkshire and The Humber compared with 4.9% (95% confidence interval: 3.8% to 6.2%) in the South West.

"The populations in the South and East of England have positivity rates below the England national average.

"Confidence intervals are large for some regions indicating high uncertainty in those estimates but there is still evidence of differences in the percentage of people testing positive for antibodies between regions."

The ONS adds the figures exclude infections reported in hospitals, care homes and other institutional settings.

In Wales, an estimated one in 10 people would have tested positive, one in 13 in Northern Ireland and one in 11 in Scotland.
