"The outbreak is accelerating and we've clearly not reached the peak of the pandemic," WHO director-general Tedros Adhanom Ghebreyesus told a virtual press conference.

"We acknowledge that there is emerging evidence in this field... therefore we believe that we have to be open to this evidence and understand its implications," the WHO's Professor Benedetta Allegranzi told a virtual press briefing.
