The flu has returned to Europe at a faster pace than expected this winter, as it almost disappeared a year ago, raising concerns about a prolonged dual pandemic amid doubts about the effectiveness of flu vaccines.
Isolation, wearing masks and social distancing, which became the norm in Europe during the coronavirus pandemic, almost wiped out the flu last year, temporarily eradicating a virus that kills around 650,000 people a year across the globe. But that has changed now as countries have taken less stringent measures to combat Covid 19, due to widespread vaccination.
Since mid-December, influenza viruses have been circulating in Europe at a faster rate than expected, said the European Center for Disease Prevention and Control. In December, the number of flu cases in intensive care units in Europe increased rapidly and the trend remains the same. The return of the virus, for experts, could be the beginning of an unusual and long flu season that can last until summer.
