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.

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 before the 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).

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.

Corona vielleicht schon seit März 2019 in Barcelona

Die Forscher wollten bislang kein weiteres Statement zu ihren Ergebnissen abgeben.
