Has the current wave peaked?
From our UK edition
Yesterday, the news was dominated by Imperial College’s React study which suggested – in contrast to the fall in recorded new infections – that the prevalence of Covid-19 in the general population was either static during the first ten days of lockdown (between 6 and 15 January), or could even have risen slightly. This morning, however, we have a second opinion in the form of the ONS infection survey, which like React is based on testing a randomised sample of the population. It suggests that the prevalence of Covid-19 did indeed fall in the first half of January – but not by all that much. Between 9 and 16 January, the ONS estimates, 1.024 million people in England and Wales were infected, the equivalent to 1 in 55 of the population.
