Experts warn leaders of huge social and economic consequences of failing to support developing states against ‘unprecedented threat’

Economists and global health experts have called on G20 leaders to provide trillions of dollars to poorer countries to shore up ailing healthcare systems and economies, or face a disaster that will rebound on wealthier states through migration and health crises.

Twenty experts, among them four Nobel prizewinners, including Joseph Stiglitz, Lord Nicholas Stern and seven chief economists of the World Bank and other development banks, have written to G20 leaders to warn of “unimaginable health and social impacts” as coronavirus rips through the developing world, taking overburdened healthcare systems beyond breaking point, and causing economic and social devastation.
