The 15 areas in Dorset with active coronavirus cases and where ONLY 15 areas of Dorset have reported more than three active coronavirus cases as the spread of Covid-19 continues 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, April 18. 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, which can be found through this link, 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.
