The Manchurian pandemic of pneumonic plague (1910-1911).

China's winter of 1910-1911 was one of its most difficult. A deadly airborne pneumonic plague, believed to have originated from tarbagan marmots, broke out in October 1910 in a northeastern Chinese province commonly known by the exonym Manchuria. The disease had a near 100 percent mortality rate, affecting mainly the lower socio-economic classes and eventually killing more than 60,000 people over six months. By April 1911, the epidemic was suppressed, in large part due to the efforts of a Western-educated Chinese physician, Wu Lian-Teh. Similar to the recent COVID-19 pandemic, the Great Manchurian Plague outbreak highlighted the importance of personal protective equipment, such as face masks, and a quick and efficient international medical response.
