Covid's first case in France may have clues to the start of the pandemic

A study that suggests a man was infected with Covid-19 as early as December 27, almost a month earlier France The first confirmed cases could be important in evaluating when and where the new one emerged, experts said Tuesday.

French researchers led by Yves Cohen, head of resuscitation at the Avicenne and Jean Verdier hospitals, retested samples from 24 patients treated in December and January who had tested negative for flu before Covid-19 developed into a pandemic. The results, published in the International Journal of Antimicrobial Agents, showed that one patient — a 42-year-old man born in , who had lived in France for many years and worked as a fishmonger — was infected with Covid-19 “one month before the first reported cases in our country”, they said.

The WHO said the results were not surprising. It is also possible that more early cases will be found, WHO spokesman Christian Lindmeier said at a UN briefing in Geneva. He encouraged other countries to investigate case records in late 2019, saying this would give the world a new, clearer picture of the outbreak.

Independent experts said the findings needed further investigation. , an expert at the University of Leeds Medical Research Institute, said it was a potentially important finding, adding: We must be cautious in interpreting these findings.

Cohen told French television on Monday it was too early to know if the patient, whose last trip to Algeria had been in August 2019, was France ’s “patient zero”. But “identifying the first infected patient is of great epidemiological interest as it changes dramatically our knowledge regarding SARS-COV-2 (the coronavirus) and its spreading in the country,” he and his coresearchers wrote in the paper.

They said the absence of a link with China and the lack of recent travel “suggest that the disease was already spreading among the French population at the end of December 2019”. France , where almost 25,000 people have died from Covid-19 since March 1, confirmed its first three cases on January 24.

Meanwhile, the United Kingdom became the first country in Europe to confirm more than 30,000 deaths. The government said 29,502 people with Covid-19 had died in UK hospitals. However, official UK statistics that take into account people who died with the suspected Covid-19 put the number of victims in Britain at over 30,000. China marked its third week without new virus deaths, as the global number exceeded 2.50,000.
