Current, the novel coronavirus variant strain that discovers in the ground such as Brazil, England, South Africa spreads continuously in European many countries.
On 28 February, Public Health England said the UK had confirmed a total of six cases of the novel coronavirus variant, first discovered in Brazil.
In France, more than 50 per cent of confirmed cases have been infected with the mutant strain found in the UK.
Public Health England said the mutant strain, known as P.1, was first detected in Manaus, Brazil, and three related cases have been confirmed in England and Scotland.
Two of the confirmed cases in England are from the same family with a history of travel to Brazil, and the circumstances of the other case are still being investigated.
The three confirmed cases in Scotland all have a history of travel to Brazil but are not linked to the confirmed cases in England, the Scottish government said.
Public Health England said the P.1 strain shares some characteristics with the one first discovered in South Africa, and that further research was needed on the effectiveness of the existing vaccine against the P.1 strain.
But no matter how the novel coronavirus mutates, it spreads in the same way, meaning prevention measures have not changed.
Nearly half of the new infections confirmed in France were with mutated strains
French Health Minister Jean-Claude Salomon said on February 28 that the novel coronavirus variant, first discovered in the UK, has become the main virus circulating in France, accounting for 53% of positive cases.
Some border areas between Germany and France have been strengthened to control the movement of people
In addition, the recent spread of a mutated strain, initially detected in South Africa, has accelerated in the eastern French province of Moselle, which borders Germany.
French and German officials recently held consultations on the situation and epidemic prevention measures in the border areas.
After consultations, Germany and France have agreed not to close the border, but to submit a 48-hour proof of a negative nucleic acid test for people crossing between the two countries, French State Secretary for European Affairs Clement Bona said February 28.
