Wuhan confines one million inhabitants

Two studies point to Wuhan as the origin of COVID


R. Gelfenstein - A district of the Chinese city of Wuhan was confined on Wednesday for the first time since the beginning of the pandemic in this city in 2020, resuming unprecedented measures since April of that year. The district in question, Jiangxia, has locked up the one million people residing there after registering four asymptomatic cases of COVID-19.

Jiangxian authorities have urged residents to stay home and not go out unless absolutely necessary. The measures include the closure of public transport and the closure of entertainment venues for three days.

The COVID policy followed by China aims to eradicate coronavirus infections, known as the COVID zero strategy.

Alarm bells went off again the day after the journal Science published two studies naming Wuhan as the hometown of COVID-19. The investigations, led by Michael Worobey and Jonathan Pekar, have as a novelty the spatial, environmental and molecular analyses of the Huanan market, a place that guarantees to have hosted the first case of coronavirus in the world.

The studies conclude that it is very likely that SARS-CoV-2 was present in live mammals sold in this market at the end of 2019 and also suggest that the genomic diversity of SARS-CoV-2 before February 2020 probably included only two distinct viruses. viral lineages, designated A and B.
