The world's richest nations prepared more costly measures on Tuesday to combat the global fallout of the coronavirus that has infected tens of thousands of people, triggered social restrictions unseen since World War II and sent economies spinning toward recession.

With the highly contagious respiratory disease that originated in China racing across the world to infect more than 196,000 people so far, governments on every continent have implemented draconian containment measures from halting travel to stopping sporting events and religious gatherings.

While the main aim is to avoid deaths — currently at over 7,800 — global powers were also focusing on how to limit the inevitably devastating economic impact.
