China’s Progress Against Coronavirus Used Draconian Tactics Not Deployed in the West

这篇文章认为,武汉的两个经验有效的阻止了新冠病毒的传播并降低了死亡率:

  1. 及时的追踪隔离疑似患者和密切接触者;
  2. 将患者按症状分类,重症才进医院,轻症进方舱,降低了医疗系统的负担。

Health experts say other countries short of testing kits can also learn from Wuhan’s experience. Unable to test thousands of suspected cases, on Feb. 4, health authorities allowed doctors to use chest scans to make coronavirus diagnoses in Hubei.

That resulted in a spike in confirmed cases, stunning the outside world. By Feb. 19, however, the number of newly confirmed cases in Wuhan had dropped into the hundreds and by March 11, it was down to single digits. The number of deaths has declined steadily since Feb. 18.

A recent study led by doctors at Wuhan’s Tongji Medical College estimated that the reproduction number of the virus—the average number of people infected by each infected person—was about 3.68 in Wuhan before the lockdown began on Jan. 23.

That number, which has to be reduced to below one to stop an epidemic, dropped to 0.32 between Feb. 2 and 18, the study found.
