The epidemic rebound of Covid-19 continues to ebb in France this Wednesday July 27, where 20,662 people are currently hospitalized.
1,761 patients have arrived in hospitals in the past 24 hours, including 188 in critical care.
Within these intensive care units, a total of 1,253 patients were treated.
What to remember from this Wednesday
Two studies published Tuesday in the prestigious journal Science conclude that the Covid-19 pandemic began in the market of the city of Wuhan, China, thus pointing to a very probable animal origin of the virus.
The first study is a geographical analysis showing that the first cases detected in December 2019 were concentrated around the market.
The second is a genomic analysis of the virus from the first cases, showing that the virus is very unlikely to have circulated widely in humans before November 2019.
