Lower Covid-19 lethality raises doubts about confinement, says epidemiologist
Stanford’s John Ioannidis says data on benefits of constraints is missing and decisions need to consider uncertainties
There are still important unanswered questions about Covid-19, but we’ve made enough progress to avoid measures of social restriction as much as possible, says John Ioannidis, professor of epidemiology at Stanford University (USA).
He has just published a paper in which he calculates a lethality rate due to coronavirus infection much lower than the approximately 4% previously predicted. On average, 0.23% of those who contract SARS-Cov-2 die, show Ioannidis calculations, with great variation in relation to age: for those under 70, the lethality is 0.05% of those who are infected .
