Global coronavirus infections exceeded 50 million on Sunday, according to a Reuters tally, with a second wave of the virus in the past 30 days accounting for a quarter of the total.
October was the worst month for the pandemic so far, with the United States becoming the first country to report more than 100,000 daily cases. A surge in Europe contributed to the rise.
The latest seven-day average shows global daily infections are rising by more than 540,000.
More than 1.25 million people have died from the respiratory disease that emerged in China late last year.
