Worldwide coronavirus cases crossed 40 million on Monday, as the onset of winter in the northern hemisphere fuelled a resurgence in the spread of the disease.
The tally is based on official reporting by individual countries. Experts believe the true numbers of both cases and deaths are likely much higher, given deficiencies in testing and potential under-reporting by some countries.
The pace of the pandemic continues to pick up. It took just 32 days to go from 30 million global cases to 40 million, compared with the 38 days it took to get from 20 to 30 million, the 44 days between 10 and 20 million, and the three months it took to reach 10 million cases from when the first cases were reported in Wuhan, China, in early January.
There were an average of around 347,000 cases each day over the past week, compared with 292,000 in the first week of October.
