L’EMEA si prepara a una possibile epidemia di influenza il prossimo inverno

I dati provenienti dalla sorveglianza dell’influenza nell’emisfero australe potrebbero servire a prevedere le epidemie di influenza nell’emisfero nord1. Intensificando le campagne antinfluenzali, si potrebbe riuscire a prevenire malattie gravi e ricoveri correlati all’influenza2.

Grazie alle misure in atto volte a contenere la pandemia di COVID-19a (ad es. uso di mascherine, distanziamento sociale e limitazione dei viaggi internazionali), i tassi globali di influenza sono stati relativamente bassi nel 2020 e nel 20213.
