The new coronavirus pandemic raging around the globe will worsen if countries fail to adhere to strict healthcare precautions, the World Health Organisation (WHO) warned on Monday.
Mr Tedros, whose leadership has been criticised by US president Donald Trump, said that of 230,000 new cases on Sunday, 80 per cent were from 10 nations, and 50 per cent from just two countries.
