So just how bad is the flu epidemic?
It's bad enough for France's Health Minister Marisol Touraine (see pic below) to call on hospitals across the country to delay non-urgent operations in order to free up hospital beds for patients suffering from flu.
Hospitals were also told to enact emergency plans that allow them to make more beds available.
The move comes after Touraine admitted hospital emergency wards in the country were at breaking point.
"Emergency services are particularly in demand and they're at the limits of their capabilities," she said at a press conference on Tuesday.
Touraine also warned that the “toll would be heavy” given the high number of people suffering from the outbreak.
According to the monitoring site Sentinelles-Inserm, nearly 800,000 people in France have been to consult a GP about flu-like symptoms in the last four weeks. Some 600 have been admitted to intensive care in hospital and 52 have died.
Around the country some 142 hospitals out of a total of 840 were at "stress level".
Why is it so bad?
This year's flu is a virulent strain of the virus type A (H3N2), a cousin of a flu that contributed to 18,000 deaths in France two years ago, public health authorities say. Last year's outbreak of type B flu was far less deadly.
“The H3N2 is a particularly dangerous virus for vulnerable people,” said Daniel Levy-Bruhl, from the health body Santé Public France.
The strain could make existing heart or respiratory conditions worse for those with existing health problems.
This winter's strain is continuing to take lives of mainly elderly people.
At the weekend, the health ministry ordered a probe into the deaths of 13 residents of a nursing home in the eastern city of Lyon late last month.
The Department of Health has said that 11 million people are vulnerable, particularly pregnant women, those over the age of 65, and the chronically ill.
Is it worse than previous years?
At the moment it's not hit as hard as the outbreak in 2014/2015 when some 2.9 million people were struck down with flu and the virus contributed to the deaths of 18,000. But authorities fear it is heading that way.
What has made matters worse is that the outbreak hit France a month earlier than normal. In December the health ministry said the epidemic has hit around a month earlier than it did in the past two years, and reportedly the earliest it has come in the last ten years.
And it hit hard. A December 21st bulletin from the Ministry of Health noted that nine out of France's 13 regions were already at "epidemic" level.
"As soon as we identified the virus we knew the impact would be serious,” said Daniel Levy Bruhl from Santé Publique France, adding that the number of people hit is no more than in an average year, but the number of people hospitalized is far higher.
Are certain regions worse than others?
The outbreak began in Brittany and the greater Paris region in December, before spreading around the country.
The latest reports say it is easing off in several regions, including Hauts de France in the north, Brittany in the west, Auvergne-Rhône Alpes in the centre and Occitanie in the south west.
The number of flu cases were also dropping in Burgundy, according to a report in Le Monde.
But the Paris region continues to be badly hit with hospitals talking of an “exceptional saturation”.
“We're cracking, everywhere,” said one hospital staff union chief in Paris.
The latest map below from the website Sentinelles-Inserm shows the worst hit areas.
So is the worst behind us?
Not really. According to predictions from health officials the flu epidemic will peak at some point next week, although in some regions it may have peaked already.
What is France doing about it?
Apart from the emergency measures being taken at hospitals, the government is urging members of the public to take their own preventative measures.
It recommended that elderly and vulnerable people in particular seek out vaccinations from their local health care professionals.
The department said that people should take extra measures to ensure they stay healthy, including: Drinking plenty of water to stay hydrated, washing your hands regularly, avoid going out if possible, throwing used tissues in a closed bin.
There is also talk now of forcing health professional to have flu vaccination, currently only around 25 to 40 percent of staff have taken up the option so far.
