International Monetary Fund managing director Kristalina Georgieva has described the scale of the Covid-19 economic crisis as "the worst economic fallout since the Great Depression".
In a speech, the IMF leader said the world was being confronted with a "crisis like no other".
"Covid-19 has disrupted our social and economic order at lightning speed and on a scale that we have not seen in living memory," she said.
"The virus is causing tragic loss of life, and the lockdown needed to fight it has affected billions of people.
"What was normal just a few weeks ago — going to school, going to work, being with family and friends — is now a huge risk."
