What is known about the new Covid subvariant spreading through France?
France has reported the highest number of cases within Europe. It can cause unusual symptoms and one expert says it could lead to a ânew winter Covid waveâ
France has reported the highest number of cases of a new Covid subvariant - dubbed JN.1 or BA.2.86.1.1 - of European countries, health authorities report, warning that it is spreading fast.
Health authority Santé publique France (SPF) issued the warning during its most recent risk analysis report, updated on November 17.
What is the new strain?
The new JN.1 is from the Omicron strain âfamilyâ and is a sub-strain of Pirola (BA.2.86), a sub-variant of Omicron.

SPF said that around 10% of tests in October had been positive for JN.1.
What are the symptoms of the new strain?
The symptoms are in many cases very similar to previous strains of Covid, including fatigue, a cough, headaches, fever, a runny nose, and a loss of smell or taste.
However, in rare cases, Pirola and its sub variants can also cause eye irritation and a rash on the face. It can also cause diarrhoea and stomach cramps.
Is the new strain of particular concern?
Expert epidemiologist Professor Antoine Flahault - who is also Regional Director of WHO-Europe in charge of the stabilisation of Covid-19 - has said that France and Ireland are âthe two epicentres of this [new] emerging epidemicâ, with France a particular âhotspotâ.
However, SPF said that âat this stage, analyses have not identified any signals of concern for either BA.2.86 or JN.1. However, there are still a number of cases under investigation which may affect these resultsâ.
Prof Flahault has said that it could cause a ânew winter waveâ.
âIt could cause an increase in the incidence [number of cases per 100,000 people]â, he said, in an interview with La DĂ©pĂȘche .
âFrance is currently in the midst of an epidemic decline, following a wave that began in mid-summer and peaked a few weeks ago,â he said.
âNow, thanks to the populationâs very solid immunity coverage, thanks to vaccination and the repeated reinfections of recent years, the waves of Covid-19 are no longer creating the hospital overcrowding or excess mortality we saw at the start of the pandemic.
âBut new waves continue to manifest themselves in flu-like syndromes that require sufferers to stay in their rooms for two to four days, and lead to persistent forms of Covid that can be very disabling.â
A new winter wave?
He said that the stopping of barrier measures, such as wearing a mask in crowded spaces, is âfacilitating the spread of respiratory virusesâ.
However, he said that the measures had partly been relaxed due to the drop in Covid mortality, which was âa good thingâ.
But the professor did add that JN.1 could âbecome established in the Ăle de France region over the next few weeks [and] when it exceeds 50-60% of the sequences analysedâŠ[it could] very probably lead to a new wave, this time in winterâ.
Why is France particularly affected?
Professor Flahault said that this was not yet clear.
He said; âFor reasons unknown to me, France is an âepicentreâ of this emerging JN.1 epidemic. We still donât know much about the characteristics of these new variants in terms of transmissibility and virulence.â
Yet, he said that despite the cases identified, âno alarming reports have been received to dateâ.
