The number of COVID-19 cases globally is likely to pass 200 million in the next two weeks, World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus said on Friday.

"Almost four million cases were reported to WHO last week, and on current trends, we expect the total number of cases to pass 200 million within the next two weeks. And we know that is an underestimate," Tedros said at a press conference.
