Sentinel surveillance of SARS-CoV-2 in wastewater anticipates the occurrence of COVID-19 cases

(13.06.2020)

This SARS-CoV-2 early detection in sewage supports the idea that COVID-19 cases may have been present in the population beforethe first imported case was reported. COVID-19 carriers may have been misclassified as influenza diagnoses in primary care, boosting community transmission before public health measures were taken(11).

(…)

Most COVID-19 cases show mild influenza-like symptoms (14)and it has been suggested that some uncharacterized influenza cases may have masked COVID-19 cases in the 2019-2020 season (11).

Coronavirus schon im März 2019 im Abwasser in Barcelona nachgewiesen

Und dann beschlossen sie, Proben aus den Jahren 2018 und 2019 Tests zu unterziehen. „Alle Proben waren negativ auf das SARS-CoV-2-Genom mit Ausnahme der Probe vom 12. März 2019, in der die SARS-CoV-2-Werte sehr niedrig waren, aber mittels PCR-Test waren sie eindeutig positiv„, erklärt Albert Bosch, Professor an der Fakultät für Biologie der UB und Koordinator der Studie.

Coronavirus schon im März 2019 in Abwasser von Barcelona nachgewiesen

(28.06.2020)

Wenn das Ergebnis bestätigt werde, würde dies das Datum des ersten Auftretens des neuartigen Coronavirus weltweit bei weitem vorverlegen.

Es bestehe die Möglichkeit, dass viele COVID-19-Infektionen weltweit zunächst als Grippe diagnostiziert und behandelt worden seien, so die Wissenschaftler weiter.

EU will Abwasser untersuchen lassen

Sinkevicius verwies zudem darauf, dass die Analyse von Abwasser „ein bewährtes Konzept bei der öffentlichen Gesundheitsüberwachung ist“. Hintergrund: Beispielsweise nutzen mehrere europäische Metropolen wie Barcelona Stichproben von Abwassern, um Erkenntnisse über die Menge und die Art des Drogenkonsums zu gewinnen.

Researcher confirms detection of coronavirus in Barcelona wastewater on March 12, 2019

Exclusive interview with Professor Albert Bosch, University of Barcelona. He explains how his study detected the novel coronavirus in wastewater samples collected in Barcelona on March 12, 2019.

SARS-CoV-2 detected in waste waters in Barcelona on March 12, 2019

(26.06.2020)

According to the researchers, these results show the validity of the surveillance of waste waters to anticipate cases, specially considering the significant contribution of the asymptomatic and pre-symptomatic carriers in the spreading of the virus. “Those infected with COVID-19 could have been diagnosed with flu in primary care by mistake, contributing to the community transmission before the public health took measures”, notes Albert Bosch, also president of the Spanish Society of Virology.

“In the specific case of Barcelona –the virologist continues–, having detected the SARS-CoV-2 spread a month before could have improved the response to the pandemic”.

Analysis of frozen samples from 2018 and 2019

These results encouraged the researchers to analyse some frozen samples between January 2018 and December 2019, with the shocking results of the presence of SARS-CoV-2 genome in March 2019, before any notification of COVID-19 cases in the world. “All samples were negatives regarding the SARS-CoV-2 genome presence except for March 12, 2019, in which the levels of SARS-CoV-2 were low but were positive, using two different targets”, says the researcher.

Study Suggests Coronavirus Emerged Much Earlier Than Thought. Some Are Skeptical.

Scientists not involved in the study seriously doubt the findings, which challenge the current consensus on where and when the virus originated.

SARS-CoV-2 Traces Detected in Barcelona Waste Water From March 2019

(27.09.2020)

Please note, the study from University of Barcelona is a preprint and as such has not undergone peer review yet.

COVID-19 was announced in Wuhan (China) in early December in 2019 and it would reach every place worldwide later, including Europe.
