What Can and Can’t Be Learned From a Doctor in China Who Pioneered Masks
The New York Times
Dr. Wu Lien-Teh helped change the course of a plague epidemic in the early 20th century and promoted the use of masks as a public health tool.
In late 1910, a deadly plague started spreading in the northeast reaches of China, reaching the large city of Harbin. Tens of thousands of people coughed up blood; their skin pruned and turned purple. They all died. This outbreak sent the Qing government into a tailspin: They didn’t know what illness was causing these deaths, let alone how to control it. So they brought in one of the best trained doctors in Asia at the time, Dr. Wu Lien-Teh. After performing autopsies, Dr. Wu found Yersinia pestis, a bacterium similar to the one that had caused bubonic plague in the West. He recognized Manchuria’s plague as a respiratory disease and urged everyone, especially health care professionals and law enforcement, to wear masks. Chinese authorities, heeding his call, coupled masking with stringent lockdowns enforced by the police. Four months after the doctor was summoned, the plague ended. Although often overlooked in Western countries, Dr. Wu is recognized in world history as a pioneer of public health, helping to change the course of a respiratory disease spread by droplets that could have devastated China in the early 20th century, and perhaps spread far beyond its borders.
