With 517 cases of invasive infections in three months, GAS, a group A streptococcus bacteria, is causing panic in Japan, even leading to the cancellation of a qualifying match for the 2026 World Cup. Most of the time harmless , she can prove to be a formidable “flesh eater”. It has already occurred in France. Should we be worried? Professor Loubet, infectious diseases specialist in Nîmes, deciphers the truth/false facts regarding the microorganism.
Professor Paul Loubet is head of the infectious diseases department at Nîmes University Hospital.

Should we be afraid of “flesh-eating bacteria”?
It is a Streptococcus A, a bacteria that is mostly not very pathogenic, which lodges either on the skin or in the oropharyngeal sphere, causing mild infections in children and adults.
But it happens to pass under the skin and it then causes dermatitis. Most of the time it is at the level of the legs.
Under the skin, it can destroy tissues, leading to necrotizing fasciitis. This is relatively rare but the situation then requires surgical treatment in the emergency room, sometimes a stay in intensive care, antibiotic therapy, etc.
In the most serious cases, we can go as far as toxic shock: the bacteria releases toxins which cause an inflammatory reaction in all organs.
But once once more, in 95% of cases, the bacteria causes benign conditions.
So you’re not worried?
No, the situation is being monitored by learned societies.
Have you ever encountered a patient in a critical situation due to Strep A?
Never.
What makes the situation turn upside down?
Because the treatment of a patient is too late, because we are weakened by age, illness, cancer, because we are in the presence of a particular strain.
“With wearing a mask, our immune system did not work to protect us”
How is it transmitted?
Human to human, by air. To protect yourself, you must wear a surgical mask. It is also the diligent wearing of the mask, during the Covid years, which might explain why we find ourselves today exposed to the emergence of this problem, our immune system has not “worked” to protect us. It is today a problem in Japan, but we had the same phenomenon in France in December 2022 ((Editor’s note: the general directorate of health had alerted regarding the situation. In the first quarter of 2023, 1152 serious cases were thus recorded in France, ten times more than in the first quarter of 2022).
And it is once more the same phenomenon which might explain why we had a resurgence of other bacteria, mycoplasma, in France, last fall, following an outbreak in China, where the use of drugs might lead to resistance. .
Streptococcus A is not a resistant bacteria…
No, it is sensitive to amoxicillin, but you should be wary of the resistance that certain strains might acquire.
Is it the “nastiest” of bacteria?
No, there are more invasive ones! And we must not forget Staphylococcus aureus…
“Bacteria are everywhere in our body”
With global warming, is there a risk of unknown, potentially dangerous bacteria appearing?
There are no major discoveries.
I remind you that this is an “old” bacteria. We’ve known her for a long time.
Unlike viruses, there are “good” bacteria…
Yes, and bacteria are everywhere in our body. To take the example of the intestinal microbiota, it is rich in more than 7000 strains of bacteria without which we might not live…
The “colonization” of the body by bacteria is not a problem. The problem, revealed by symptoms (fever, cough, etc.), can only arise when there is an infection.
