The 32 areas of Berkshire where there are coronavirus cases THERE are 32 areas of Berkshire which are reporting coronavirus cases - but cases continue to fall across the county. An interactive map, which uses Public Health England data, shows how many people have tested positive for the virus in each area of the county over the seven-day period up to Sunday, March 28. Public Health England breaks down the numbers of coronavirus cases into neighbourhoods called 'Middle Super Output Areas' (MSOAs), which are smaller than council wards and based on population rather than geographical area. The interactive map allows users to type in their postcode and see how many cases were reported in their area and if it has increased or decreased from the week before. The darker the colour on the image, the more positive test results have been recorded.
