What is France doing to control the spread of new Covid variants?

New, more infectious variants of Covid first discovered in the UK, South Africa and Brazil are spreading steadily in France, prompting fears of an explosion of cases and a third lockdown. Here's what France is doing to halt the spread.

The emergence just before Christmas of new, more infectious strains of the Covid virus in the UK, South Africa and Brazil has been the cause of much worry in France, with the spread of the new strains one of the major reasons given by people pushing for a third lockdown.

Overall case numbers remain broadly stable in France at around 20,000 new cases a day, with a slight fall observed over the past week. 

In his briefing on Thursday evening, health minister Olivier Véran said that variants now account for 25 percent of cases in France.

The percentage of variants detected has seen a steady rise since January and scientific modelling predicts that the new variants will be the dominant strain of the virus in France by March.

All three seem to be more contagious than the classic Covid virus, and there seems to be some evidence that the AstraZeneca vaccine is less effective against the South African strain.

At present most of the variants are the UK variant, but the South African and Brazilian variants are also seeing a steady growth, representing between 4 and 5 percent of all cases.

In Dordogne 40 cases have been detected, which health bosses say are linked to a cluster.

The département of Moselle in eastern France presents a “very worrying” situation, said Véran, with 300 cases of the Brazilian and South African variants detected. These cannot at present be linked to a single cluster, or to people who have travelled or their contact cases.

Véran travelled to the département on Friday for emergency discussions with local leaders.

While all options remain on the table, including local lockdowns in affected areas, the French government at the beginning of February decided against a third national lockdown for now, but has brought in a collection of new measures aimed at curbing the spread of the variants.

Travel bans

In January France announced the closure of its borders to all non-EU travel, apart from in a limited range of exceptions.

To travel to or from France from a non EU country travellers need a vital reason including essential work or the death of a close family member. Travel from non EU countries, including the UK, is not allowed for tourism, family visits or visits from second home owners.

Anyone who does have an essential reason for travel – which includes an exemption for hauliers coming from the UK – needs a negative Covid test to enter France.

Travel from within the EU is allowed for any reason, but people still need a negative Covid test, with some exemptions including cross-border workers.

New testing

In order to track the progress of the variants, France had conducted several 'flash' surveys of positive test results to screen for variants, but now is screening all tests for the presence of variants.

All PCR tests in France will now be analysed in labs by a new test multiplex – which is capable of detecting the presence of the existing strain of Covid or one of the new variants with a single test, thus saving valuable time in tracking the new variants. These are now being used in labs in France and will shortly completely replace the older style of test, said Véran.

This screening applies only to PCR tests, and not the rapid-result antigen tests which are available in pharmacies.


Those infected by the South African or Brazilian variants must self-isolate for 10 days instead of seven. After that they may only exit quarantine upon taking a test that comes back negative. If the test comes back positive they must self-isolate for another seven days.

Those who test positive for the variant first discovered in the UK are not subject to stricter self-isolation rules and may continue to follow the general rules.

School rules reinforced

The government has also banned the use of fabric masks in schools, asking that all pupils wear surgical masks of the more protective type 'category 1'.

A class will also immediately close if a pupil is discovered to be infected by the variants first discovered in South Africa or the Brazil. If one pupil is a contact case for a parent or sibling diagnosed with the variants, the class will also close. Classes will only close if there are three or more cases of the classic Covid virus or the UK variant, as per the previous rules.

Contact cases

Anyone who is identified as a contact case of either the South African or Brazilian variants are urged to get immediately tested, with health authorities asked to offer them a test the same day, according to the new rules.

Home visits

Anyone identified as having the South African or Brazilian variants will be offered the possibility of having a domestic nurse come check up on them.


Schools have banned fabric masks, which are ruled to be less effective against the new variants. For the rest of the population fabric masks are still allowed, but the government advises the use of surgical masks as the most effective.

New Covid wave in autumn ‘virtually certain’ say French experts

The head of the government's new health advisory body says that a surge of Covid cases when the French head back to work after the summer break is virtually certain.

New Covid wave in autumn 'virtually certain' say French experts

Immunologist Brigitte Autran, president of new government health advisory body the Comité de veille et d’anticipation des risques sanitaires (Committee to monitor and anticipate health risks) which has replaced the Conseil scientifique, told Le Parisien that “the Covid epidemic is not behind us” and said that the French would have to get used to “living with” the virus.

The Covidtracker website currently shows that the virus is in decline across France, with the R-rate currently at 0.7 – any figure lower than one indicates that the number of infections is falling.

Autran, whose appointment as head of the new body was confirmed on Wednesday, said that the most likely scenario was for a “new epidemic peak in the autumn”, when people return to work after the summer holidays.

“Will it be due to a new variant or the return of cold weather?” she said. “We are not soothsayers, but it is almost certain that there will be a wave.”

“Today, we must go towards living with it,” she added, reintroducing the French to an expression previously used by President Emmanuel Macron and several ministers.

“This does not mean accepting the deaths or the severity of the disease,” she went on, pointing to the fact that health authorities in France still have “levers to activate” to fight the virus. 

Despite the fact that nearly 80 percent (79.6 percent) of people over the age of 12 are fully vaccinated against the virus, she said that, “unfortunately there are still too many people who have not been vaccinated or revaccinated.”

And she said the new body would work with the government to improve the public’s access to drugs, such as Paxlovid, and vaccines.

Vaccination is still open to anyone who has not yet had their shots, while a second booster shot is on offer to certain groups including over 60s, pregnant women, those with health conditions or people who are in close contact with vulnerable people.

The French government in August voted to end to State of Emergency that allowed it to impose measures like travel bans and lockdowns, although further restrictions could be put in place if cases rise again and parliament agrees.
