The Covid self-reporting app Zoe suggests Bristol is currently one of the worst-affected areas in England for coronavirus infection. Its interactive map estimates that there are more than 91,000 'active cases' of the virus in Bristol city, which dwarfs the latest official figure from the government.
Unlike the government's statistics, which only register positive covid tests and has stopped reporting over Christmas, the Zoe Health Study uses self-reported positive tests and data modelling to calculate how many people in each area are likely to be infected. Bristol and some of the area around it are modelled as having the highest infection rate in the country.
In total, Bristol is estimated to have 91,119 Covid-positive people, from a self-reporting sample of 1,878 people in the city. This would equate to roughly one in five inhabitants. Of the areas covered by the app, Bristol accounts for more than a third of the 234,178 modelled cases in the UK.
