an unprecedented “triple epidemic” of uncertain evolution, public health alert France

The flu hits the metropolis early, adding to a rebounding Covid and bronchiolitis at record levels.

The “triple epidemic” facing France, with the simultaneous circulation of Covid, bronchiolitis and influenza, is “completely new“And its evolution still difficult to predict, underlined this Friday, December 2 Public Health France.

The flu hits the metropolis early, adding to a rapidly rising Covid and bronchiolitis at record levels for more than 10 years in infants. This situation hits an already tested health system, as in other countries, notably the United States.

An “unprecedented” situation

The situation is completely new» and filled with «uncertainties“, summed up Didier Che, deputy director for infectious diseases, during a press briefing from the public health agency. “In previous years, there were rather respiratory viruses which followed one another: a first circulation of rhinoviruses gave way to RSVs (main virus involved in bronchiolitis Ed), which, very generally, gave way to influenza. There, we have co-circulations“, detailed the epidemiologist Sophie Vaux.

This condition is “disturbing“because the addition of these pathologies can lead to “a fairly strong clinical impact, particularly on hospitals“, she added. And this, even if these viruses do not affect “not exactly the same populations“, the flu and the Covid mainly affecting the oldest and most vulnerable, bronchiolitis mainly infants. He is “difficult to predict the occurrence of peaks» of the three epidemics, in particular a possible simultaneous peak of Covid and influenza, or even bronchiolitis, at Christmas.

One of the big unknowns is a possible competition between the influenza and Covid viruses which could make it difficult for them to coexist and limit the risk of simultaneous peaks. “It still takes a little time to know if this notion of viral cannibalism is confirmed.“, judged Didier Che for which he is also”too early to draw conclusions from the US situation“.

But, he insisted, France is notnot yet completely destitute» and has «a preventive arsenalin the face of this triple epidemic. Public Health France has insisted more than ever on vaccination against Covid but also the flu, as the end of the year celebrations approach with family gatherings conducive to the transmission of viruses. Barrier gestures (mask in closed places, hand washing, ventilation, etc.) are also strongly recommended.
