Understanding what works: How some countries are beating back the coronavirus
With Europe and the United States locked in deadly battle with the coronavirus that causes Covid-19, a number of countries that were hit early by the virus are doing a far better job of beating it back.
China, which is now diagnosing more cases in returning travelers than in people infected at home, reported no new domestically acquired cases on Wednesday, for the first time in more than two months. South Korea, which had an explosive outbreak that began in February, is aggressively battering down its epidemic curve. Singapore, Hong Kong, and Taiwan have together reported only about 600 cases.
