World Health Organization says 'test, test, test' for coronavirus

The World Health Organization called on all countries on Monday to ramp up their testing programmes as the best way to slow the advance of the coronavirus pandemic. "We have a simple message to all countries - test, test, test," WHO Director General Tedros Adhanom Ghebreyesus told a press conference in Geneva.

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