WHO chief: 'Test, test, test” for coronavirus

The World Health Organization (WHO) called on all countries to ramp up their testing programmes as the best way to slow the advance of the coronavirus pandemic.

"You cannot fight a fire blindfolded. We have a simple message for all countries - test, test, test," WHO Director-General Tedros Adhanom Ghebreyesus told a news conference in Geneva.

Without testing, cases could not be isolated and the chain of infection would not be broken, he added.
