AN AREA of Portland has yet again recorded the highest number of Covid-19 cases in Dorset – one week after cases in the area surged. Public Health England breaks down the numbers of Covid-19 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 online, 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.
