increase in the number of cases of PIMS, an anti-inflammatory syndrome that affects children

In a document published Thursday, the Public Health Agency France is alarmed by a “very marked increase” in cases of pediatric multi-system inflammatory syndrome since the beginning of the year, a set of cardiac disorders which often reflect the rare severe forms of Covid-19 in children.

PIMS is spreading among young children. Public Health France is alarmed, in a report released Thursday, of the “very marked increase” in cases of pediatric multi-system inflammatory syndromes in France since the beginning of the year. She also warns that “the amplitude of the current wave could turn out to be greater than that of the previous wave”.

According to the health authorities, more and more children have been developing serious forms of Covid since the beginning of the year, which are manifested by heart problems often associated with violent digestive symptoms.

Rare but particularly serious cases

The public health agency specifies that the “very clear” and very dreaded “increase in cases of PIMS” corresponds mainly to the “first three weeks of the year 2022”. But serious forms of Covid-19 in children can however be observed since March 2, 2020, the very start of the pandemic in France. In total, 849 cases of PIMS with a proven link to Covid-19 have been identified in the territory, in the majority of cases in children under the age of 11.

The report reveals that 353 of the 849 children who suffered from this syndrome had to be sent to the intensive care unit (42% of them) and 250 to continuing care units (29% of them). Boys also seem to be more affected by this serious form, since they represent 60% of hospitalizations in France. A nine-year-old child who had developed this inflammatory syndrome died of it, we still note in this report.

Fever, nausea, vomiting…

The symptoms of this syndrome are as follows: high fever, intense fatigue and deterioration of general condition, chills, abdominal pain, nausea or vomiting. Santé Publique France also tells us that these serious forms occur some time after infection with Covid-19, that is to say four to five weeks later on average.

In its document, Public Health then warns that the spread of this syndrome is tending to accelerate in the territory. So much so that the agency draws a grim outlook, and warns: “The amplitude of the current wave could prove to be greater than that of the previous wave (related only to the circulation of the Delta variant), with gradual replacement of the Delta variant by the Omicron variant among Covid-19 cases”.

“In France, the cumulative incidence of PIMS in connection with Covid-19 has been estimated at 5.9 cases per 100,000 inhabitants in the population under 18”, further summarizes Public Health France in its report which underlines that the he median age of the young patients concerned is 7 years old.
