The world has reached the grim milestone of 20 million confirmed coronavirus cases and is edging closer to 750,000 deaths globally, according to figures from Johns Hopkins University. Case numbers have soared exponentially since the first were reported in China in December. The world recorded one million cases more than three months later, on April 2. The tally hit 10 million cases less than three months after that, on June 28, and it has taken just six weeks to double. The rise in cases remains driven in large part by the region of Latin America and the Caribbean, as well as by Asia, where cases are growing again, according to the JHU figures. Death rates remain highest in the former.
