A discovery made during an examination of a pre-pandemic sewage sample now threatens to upend conventional thinking on the origins of the virus behind COVID-19.
University scientists first went looking for traces of the coronavirus in samples from Barcelona's sewage system to determine if wastewater could be an accurate predictor of COVID-19 outbreaks.
Reexamining stored samples from 2018 and 2019, researchers made a seemingly impossible discovery.
"All samples came out to be negative for the presence of SARS-CoV-2 genomes with the exception of March 12, 2019," the team revealed, using the scientific designation for the coronavirus.
Do you think the coronavirus was circulating before the outbreak in Wuhan, China?
The discovery would place SARS-CoV-2 half a world away from Wuhan, China, nine months before China's own uncontrolled outbreak threw the world into a pandemic.
While the positive March 2019 sample does indicate the virus' presence in the world well before the Wuhan outbreak, it does not change the fact that China's lies and the World Health Organization's ineptitude helped the pandemic bloom.
