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.

Clinical and epidemiological characteristics of pediatric SARS-CoV-2 infections in China: A multicenter case series

June 16, 2020

Abstract

As of April 18, 2020, over 2,000,000 patients had been diagnosed with coronavirus disease-2019 (COVID-19) globally, and more than 140,000 deaths had been reported. The clinical and epidemiological characteristics of adult patients have been documented recently. However, information on pediatric patients is limited. We describe the clinical and epidemiological characteristics of pediatric patients to provide valuable insight into the early diagnosis and assessment of COVID-19 in children.
