  • ‘They are leading us to catastrophe’: Sweden’s coronavirus stoicism begins to jar | World news | The Guardian

    A petition signed by more than 2,000 doctors, scientists, and professors last week – including the chairman of the Nobel Foundation, Prof Carl-Henrik Heldin – called on the government to introduce more stringent containment measures. “We’re not testing enough, we’re not tracking, we’re not isolating enough – we have let the virus loose,” said Prof Cecilia Söderberg-Nauclér, a virus immunology researcher at the Karolinska Institute. “They are leading us to catastrophe.”

  • ‘Estimating the number of infections and the impact of nonpharmaceutical interventions on COVID-19 in 11 European countries’

    new paper from the Imperial College COVID-19 epidemiological team: ‘Following the emergence of a novel coronavirus (SARS-CoV-2) and its spread outside of China, Europe is now experiencing large epidemics. In response, many European countries have implemented unprecedented non-pharmaceutical interventions including case isolation, the closure of schools and universities, banning of mass gatherings and/or public events, and most recently, widescale social distancing including local and national lockdowns. In this report, we use a semi-mechanistic Bayesian hierarchical model to attempt to infer the impact of these interventions across 11 European countries. Our methods assume that changes in the reproductive number – a measure of transmission – are an immediate response to these interventions being implemented rather than broader gradual changes in behaviour. Our model estimates these changes by calculating backwards from the deaths observed over time to estimate transmission that occurred several weeks prior, allowing for the time lag between infection and death.’
