Authorities in South Korea, meanwhile, confirmed 242 new cases, bringing the national total to 7,755.

As with China, the infection rate in South Korea had slowed in recent days, bringing hope that the situation was beginning to stabilize. Though one of the world’s worst hit countries, South Korea has been lauded for its widespread testing drive, which has so far seen around 200,000 people screened for the virus.

Western countries are also struggling with their own worsening outbreaks. The number of cases in the US has now reached at least 1,000, with numerous states declaring emergencies.
