What is happening in key countries?
A team of infectious disease experts at Johns Hopkins University, in the US city of Baltimore, have been documenting the global spread of Covid-19 on its tracking website.
According to their data, the US remains by far the worst-hit country in terms of sheer numbers, with more than 6.6 million confirmed infections, and over 197,000 deaths.
The number of new daily infections has been dropping, though, after a spike in July.
Earlier this week, President Donald Trump denied downplaying the seriousness of Covid-19, despite admitting in a recorded interview to having done that.
In India, the number of known infections climbed above five million this week – the second-highest caseload in the world.
When comparing figures from different countries it is important to bear in mind factors such as population size and density. For instance, India has a population of 1.3bn people.
However, the virus appears to be spreading much faster in India than any other country, with daily cases topping 90,000 in recent days. More than 80,000 people have died, amid reports of shortages of intensive care beds and oxygen supplies.
