THREE colours on an official map - blue, green and yellow - illustrate the stark differences between the Covid rate in three adjacent districts in the York area.

The Public Health England map shows the Selby district, which is the UK's worst Covid hotspot, shaded in blue because its seven-day rolling rate for the week to April 24 is above 100, standing at 109.2 cases per 100,000 population.

The district's figures are being inflated by a Covid outbreak at Clipper Logistics in Selby.

The City of York Council area is shaded in green, because its rolling rate is between 10 and 49, standing at 21.4 cases per 100,000 population, which is just below the national average.

The Ryedale district, to the north-east of York, is shaded in yellow because its rate is between 0 and 9, standing at just 9 cases per 100,000.
