Sentinel Surveillance of SARS-CoV-2 in Wastewater Anticipates the Occurrence of COVID19 Cases
June, 2020
SARS-CoV-2 was detected in Barcelona sewage long before the declaration of the first COVID-19 case, indicating that the infection was present in the population before the first imported case was reported. Sentinel surveillance of SARS-CoV-2 in wastewater would enable adoption of immediate measures in the event of future COVID-19 waves.
Debate: Should Governments Continue Lockdown Strategy?
June, 2020
Should governments continue lockdown to slow the spread of covid-19? Until we have a meaningful alternative, lockdown is the only thing we can do to prevent further catastrophic spread of the virus, says Edward R Melnick.
But John PA Ioannidis argues that any benefits of lockdown depend on its effectiveness and the covid-19 burden—and that the harms are multifarious.
Illusory Effects of Non-pharmaceutical Interventions on COVID19 in Europe
June 8, 2020 - Stefan Homburg, Christof Kuhbandner
Abstract
Flaxman et al. (Nature, 8 June 2020, https://doi.org/10.1038/s41586-020-2405-7, 2020) infer that non-pharmaceutical interventions conducted by several European countries considerably reduced effective reproduction numbers and saved millions of lives. We show that their method is ill-conceived and that the alleged effects are artefacts. Moreover, we demonstrate that the United Kingdom?s lockdown was both superfluous and ineffective.
