A fresh strain of the H3N2 influenza virus has spurred a surge of cases across Europe, with Italy reporting over 800,000 new acute respiratory infections last week.
Flu Epidemic in Italy
Italy’s National Institute of Health (ISS) recorded roughly 817,000 new cases of acute respiratory infections last week, more than 40 percent caused by influenza viruses, and over half attributed to the novel K strain of H3N2.
ANSA reports the strain has greater transmissibility, but does not appear to cause more severe symptoms; current vaccines still protect against hospitalization, though their efficacy against clinical symptoms cannot yet be determined.
Chill in Europe
On Dec 17 the World Health Organization noted the European flu season began roughly four weeks earlier than in previous years.
At least 27 of 38 reporting countries now record high or very high activity; the new seasonal flu variant accounts for 90 percent of confirmed cases in the region.
Incidence is rising in France, Spain, Italy, and Germany, while falling in the United Kingdom.
When will the flu season end?
WHO forecasts that case numbers will continue to rise until the peak, expected at the end of December or beginning of January.
Most people will recover without medical intervention, but those with underlying conditions or severe symptoms should seek medical help.
Vaccination, personal hygiene, and staying home when symptomatic remain key preventive measures.
