The global coronavirus pandemic has inflicted an economic crisis unlike any in the past century and will require a massive response to ensure recovery, IMF chief Kristalina Georgieva said on Thursday.

The warnings about the damage inflicted by the virus already were stark, but Ms Georgieva said the world should brace for "the worst economic fallout since the Great Depression."

With nearly 89,000 deaths in 192 countries and territories and the number of cases now surpassing 1.5 million worldwide, much of the global economy has been shut down to contain the spread of the virus.

The International Monetary Fund expects "global growth will turn sharply negative in 2020," with 170 of the fund's 180 members experiencing a decline in per capita income, Georgieva said.

Just a few months ago, the fund was expecting 160 countries to see rising per capita income, she said in a speech previewing next week's spring meetings of the IMF and World Bank, which will be held virtually due to the restrictions imposed due to the COVID-19.
