As Europeans brace for a grim winter with the threat of rising COVID-19 infections, minimal numbers of flu cases recorded so far point to a possible silver lining.

Data available for Europe since the beginning of October, when flu case numbers usually start to ramp up, mirror shallow figures seen in the Southern Hemisphere earlier this year and in the United States where the flu season has also just begun.

Some doctors say a combination of lockdowns, mask wearing and handwashing appear to have hampered transmission of the flu, while warning that the data should be treated with caution because the peak of the season is weeks or even months away.
