The Huanan Seafood Wholesale Market in Wuhan was the early epicenter of the COVID-19 pandemic  

Another study published in the prestigious Science magazine confirms that the epicenter of the COVID-19 outbreaks was the Huanan Seafood Market in Wuhan, China. Among the tested over 40,000 blood samples collected from patients at Wuhan hospitals between October and December 2019, no positive test result for SARS-CoV-2 was recorded. These results confirm that the epidemic and subsequent COVID-19 pandemic was local and limited to the Huanan Market in its early stages. On the other hand, a wide spatial distribution of cases was observed only in the later stages of the epidemic in January and February.
