The rate of Covid cases attributed as being reinfections is rising in France due to the more contagious Omicron variant, health agency Santé publique France (SPF) stated in a report published Friday (April 1).
Reinfections now make up 5.4% of the total positive cases, SPF wrote.
The health authority defines re-infections as being when a person tests positive two or more times 60 days or more apart. On average, there are 242 days (nearly eight months) between reinfections.
In total, 685,858 cases recorded between March 2, 2021 and March 20, 2022 have been identified as reinfections, with 95.2% of those being reported since December 6, around the time that Omicron started to spread in France.
Around half of all reinfections were attributed to people aged between 18 and 40, and 88% were linked to the Omicron variant, SPF wrote.
“It seems likely that the waning of immunity created by vaccines or having been infected is playing a role in the reinfections,” SPF stated.
“This is particularly the case for those who have not had a booster dose.”
"It is also very likely that the high spread of the Omicron variant, characterised by an increased transmissibility and an important immune escape, amplifies this phenomenon.”
The number of reported Covid cases in France has been rising steadily since early March.
Could presidential elections lead to one million more Covid cases?
People who have tested positive for Covid “will be able to go and vote” in April’s presidential election, government spokesperson Gabriel Attal announced on Wednesday (March 30).
Following this announcement, the head of the infectious diseases department at Tenon Hospital in Paris, Gilles Pialoux, said that this could lead to one million new Covid cases.
He said that while it is not possible to prevent people from voting, “between the two rounds, that is a lot of people and if we have a very high circulation of cases…there could be a million cases in a fortnight”, he told RTL.
But other health experts have contested this.
Antoine Flahault, epidemiologist and director of the Institute of Global Health at the University of Geneva, said that the elections representing only a “small risk”.
“The trend in cases should, from next week onwards, reverse and perhaps reach a peak… so the election should not change this,” he told Le Figaro.
Mircea Sofonea, a lecturer in epidemiology and the evolution of infectious diseases at the université de Montpellier, said:
“A million cases is possible in the case of a large spread. But it won't have a dramatic impact on hospital admissions."
