Research: Evidence of SARS-CoV-2 before Wuhan outbreak in 2019

Angola, Brazil, Coronavirus, Europe, France, Italy, Origins, Spain, USA

“In the USA, SARS-CoV-2 reactive antibodies were detected in over 100 blood samples collected in several different states in early December 2019.

In Brazil, environmental surveillance monitoring demonstrated early SARS-CoV-2 community spread at the end of November 2019 by detecting viral RNA in wastewater.

A study performed in the UK identified a few blood donors in May 2019 whose sera presented SARS-CoV-2 S-reactive antibodies associated with a presumed current immune response.

In France, antibodies against SARS-CoV-2 were found in serum samples collected in November 2019, and viral RNA was detected in December 2019 in a respiratory sample from a patient hospitalised for haemoptysis.”
