As countries around the globe try to contain the spread of the novel coronavirus, nowhere is the task more challenging and the risk greater than in the developing world.

From Southeast Asia to South America, governments are struggling to enforce severe China-style lockdowns. They lack the resources to deploy the testing-heavy, tech-driven measures used by wealthier countries like Singapore and South Korea, which have had more success in keeping business and society open.

"These countries are facing some pretty dire circumstances,” said Barbara McPake, director of the Nossal Institute for Global Health at the University of Melbourne. "Their ability to lock down and isolate is more limited than developed countries.”
