The Government releases new data every week which shows the rates of positive coronavirus tests for each area per 100,000 people. The data is published each week by Public Health England.
A relatively small number of cases can make a large difference to rates and this needs to be considered when looking at weekly changes and comparisons with other areas. It's very difficult to say for certain what the reason for any increase might be. What the data does tell us, is that this is not over and now is not the time for us to be complacent.
Particularly now, with some measures introduced to ease lockdown, please continue to be vigilant and cautious. We still have to social distance and we still have to wash our hands regularly with soap and water.
