With the arrival of the K strain, Italy is facing a surge in influenza cases, particularly affecting the Campania region. This has put a strain on the healthcare system and requires greater attention to prevention, especially in view of the upcoming holidays.
It's not yet Christmas, but Italy is already in bed. The 2025 flu season has accelerated dramatically in the last week, driven by what experts have dubbed the "European variant": the K strain of the A/H3N2 virus.
According to the latest bulletin from the Italian National Institute of Health, 816 Italians have been affected by acute respiratory infections in just seven days, a jump of 100 compared to the previous survey.
The virus that "runs" faster than others
What's worrying health authorities isn't the virus's lethality, which remains similar to previous seasons, but its incredible speed of spread. Strain K has an evolutionary advantage that makes it easier to transmit, in many cases weakening the immune system against infection, although vaccines are holding up well in preventing severe cases and hospitalizations.
While the United Kingdom is seeing the light at the end of the tunnel with an initial decline in the curve, the rest of the continent is in the midst of the storm. In Germany, 7 million people are infected, in France emergency rooms are overrun (6,2% of total admissions), and in Spain, the mortality rate among hospitalized patients has reached 4,1%.
The Campania case: a surge that shakes the hospital network
While Northern Italy currently appears to be managing the influx, the South is experiencing the greatest difficulty. Campania, along with Sardinia, is the region that has seen the most sudden and violent surge.
Why is Campania hit harder?
There are several factors that are making the region a national "case" in these hours:
High population density: In metropolitan areas, particularly in Naples and its hinterland, the transmission rate of the K strain has found fertile ground.
Intergenerational contact: The strong cohabitation between young people (the main vector of the virus) and the elderly is leading to a rapid transfer of the infection to the most vulnerable segments of the population.
Pressure on Emergency Rooms: In key hospitals such as the Cardarelli in Naples and the San Giuseppe Moscati in Avellino, there has already been a significant increase in admissions for respiratory complications, often linked to bacterial superinfections.
Regional health authorities report that, in the last 48 hours, calls to 118 for respiratory crises have increased by 25%. The main concern is the upcoming holidays: Christmas lunches and dinners risk turning into "super-spreader" events, pushing the regional healthcare system close to breaking point during the holidays.
Prevention remains the only weapon
Although the K strain occasionally manages to "break through" the vaccine's protection against mild infection, the ISS reiterates the importance of prophylaxis. Data shows that those who are vaccinated almost always avoid hospitalization. With Molise the only happy island yet untouched by the epidemic, the rest of Italy is preparing for a Christmas of forced confinement, hoping that, as happened in London, the peak is near.
Expert advice: If you experience symptoms, avoid crowding emergency rooms unless absolutely necessary (severe breathing difficulties) and consult your GP by telephone to avoid overloading emergency facilities.
