A new variant of the COVVI-19, derived from omicron, could impose themselves in France if the most vulnerable populations are not better protected by vaccination. This is in any case the meaning of the press release published this Wednesday, June 25 by the National Academy of Medicine. The wise men fear a rebound in cases during the summer, a period conducive to the circulation of the virus.
An omicron varying virus is currently circulating
This variant, baptized NB.1.8.1, was placed under surveillance by the World Health Organization (WHO) from May 23.
Although it was not associated with more severe clinical forms, it caused an epidemic outbreak in Asia. And now, its presence is now growing in North America as well as in several European countries, according to the Academy.
Why this variant worries the health authorities
According to Dr Gérald Kierzek, emergency doctor and medical director of True Medical, “We could see new omicron singers appear or other more transmitted, even partially resistant “variants.
In a context where closed places, transport or festivals promote transmission, “COVVI-19 could circulate more in summer in air-conditioned areas“He warns.
In addition, health professionals fear the circulation of several viruses, already observed last winter. “A co-circulation with other viruses such as flu or VRS is possible”underlines the emergency doctor again.
Vaccination coverage, weak link in the current strategy
Vaccination remains the main lever to limit serious forms. However, only 21.7 % of the over 65s were vaccinated in February. A figure deemed “very insufficient” by the Academy of Medicine, which calls for priority to vaccinate the older people over 80 years old, immunocompromised and all people at high risk, even if they have already received a dose last fall.
“”You have to update your vaccination diagram according to the recommendations, with a possible annual reminder, especially for people at risk “, Dr. Kierzek insists. Pregnant women and adults with comorbidities are also eligible for a recall dose, if they have not received it since the end of 2024.
Beyond vaccines, “Barrier gestures remain essential: regular hand washing, disinfection of surfaces, and ventilation of enclosed spaces “he recalls. In the unveiled places, “You can open windows or use air purifiers “And “It is best to favor outdoor activities“As much as possible.
A more discreet covid, but always to monitor
Even if the profile of the virus evolves, caution remains in order. “In 2025, COVVI-19 could look like a seasonal flu for the majority of the population, but it will remain dangerous for fragile people“, estimates Dr. Kierzek. He tries on”moderate vigilance, with vaccination and barriers if necessary“, To maintain the circulation of the virus at a manageable level.
In terms of symptoms, nothing very new. “The symptoms are close to those of the recent variants of omicron: cough, fever, fatigue, sore throat, nasal flow and headache dominate, with sometimes a loss of taste or smell, less frequent than in 2020”he describes. Serious forms, “mainly concern the elderly or immunocompromised“.
In case of symptoms, its recommendation is simple. “”We isolate ourselves, we wear a mask, but the tests are not necessary “.
