Manchurian plague
pneumonic plague outbreak in 1910–1911

The Manchurian plague was an outbreak of pneumonic plague that occurred mainly in Manchuria in 1910–1911. It killed 60,000 people, stimulating a multinational medical response and the wearing of the first personal protective equipment (PPE).
The outbreak is thought to have originated from a tarbagan marmot which was carrying Yersinia pestis. The disease was spread when marmot fur hunters gathered together during the winter months, and then infected migrant workers during the Chinese New Year. The Cambridge-trained doctor Wu Lien-teh led Chinese efforts to end the plague, and promoted quarantine and the wearing of cloth face masks as safety measures. The hardest hit cities included Changchun, Harbin, and Mukden (now Shenyang). Although the disease was largely confined to Manchuria, a number of plague cases were reported in cities such as Beijing and Tianjin.
The Manchurian plague highlighted the importance of a multinational medical response, setting precedents for organizations such as the World Health Organization. Wu Lien-teh's widespread promotion of cloth face mask-wearing by doctors, nurses, patients, contacts, and (to the degree that it was possible) the population at large was the first time such an epidemic containment measure had been attempted. The event was also influential in establishing the use of personal protective equipment to stop the spread of disease, and is credited for the origins of the modern hazmat suit.

Why this record matters
“Manchurian plague” is worth following because a concise public description often conceals a longer documentary argument. Here, Manchurian, plague and pneumonic provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q91900320. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1910 and 1911.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
