France has confirmed the first case of a new coronavirus variant that recently emerged in Britain, its health ministry said.
The new strain of the virus, which experts fear is more contagious, has prompted more than 50 countries to impose travel restrictions on the UK.
The first French case – found in a citizen living in Britain who arrived from London on December 19 – is asymptomatic and self-isolating at home in Tours in central France, the ministry said late on Friday.
They were tested in a hospital on December 21, and later found positive for the strain.
Health authorities have carried out contact-tracing for the health professionals taking care of the patient, the ministry said in a statement.
Any of their contacts that were seen as vulnerable would similarly be isolated, it said.
In addition to this first case, several other positive samples that “may suggest the VOC 202012/01 variant are being sequenced” by the specialist laboratories of the national Pasteur Institute, the statement added.
On Monday, France’s health minister Olivier Veran had admitted that it was possible the newly discovered strain was already in the country.
Italian authorities have detected the new strain in a patient in Rome, while the World Health Organisation reported that nine cases have been detected in Denmark and one each in the Netherlands and Australia.
Following the snap 48-hour ban this week, France had reopened its borders to the UK – partly to allow French citizens to return home, as well as to relieve the massive build-up of freight goods – but had instituted a testing policy.
France’s interior ministry said on Thursday that limits on travel from the UK will continue “until at least January 6”.
For now, only citizens of France or the EU, those with residency rights there or business travellers are allowed to make the crossing from the UK – if they can show a negative Covid-19 test less than three days old.
British Prime Minister Boris Johnson has said the new viral strain “may be up to 70 percent more transmissible than the original version of the disease”.
Ahead of Christmas British health minister Matt Hancock announced the expansion of strict lockdown measures across further parts of the south of England to contain the spread of the disease.
With more than 68,000 deaths from the virus, the United Kingdom is one of the hardest hit countries in Europe.
