The World Health Organization says the coronavirus is continuing to gain pace globally and warns that a spike in deaths could soon follow.
WHO emergencies program chief Mike Ryan expressed concern about a marked increase in the number of daily cases.
"If you imagine that somewhere in April and May, we were dealing with 100,000 cases a day. Today we are dealing with 200,000 cases a day. That is not purely as a result of testing. This epidemic is accelerating. And we are lucky. I hope part of it is that we have become better."
Ryan says that the number of deaths appear to be stable for the moment.
But he cautions that there's often a lag time between when cases increase and when deaths are reported.
