Flu season is off to a good start. Since the beginning of autumn, according to the RespiVirNet surveillance system of the Istituto Superiore di Sanità, already 2.1 million Italians are asleep due to respiratory infections. The cause is various viruses that circulate in winter: from Rhinovirus to SarsCoV2. However, in recent weeks, the influenza virus has also grown rapidly, which is also caused by a new variant of the influenza virus A/H3N2 (subclade K), which makes the season 3-4 weeks earlier this year, as reported by the European Center for Disease Prevention and Control recently.
