Wu Lien-teh and the Manchurian Anti-Plague Campaign
In the winter of 1910, an aggressive outbreak of pneumonic plague swept across the railway networks of northern Manchuria, killing an estimated 60,000 people with a near-100% case fatality rate. Dispatched by the Qing imperial court to the rail hub of Harbin, Cambridge-educated physician Wu Lien-teh conducted

China's first modern post-mortem autopsy and proved the pathogen spread via airborne respiratory droplets rather than rodent fleas. Wu designed multilayer gauze face coveringsโthe direct design ancestor of the modern N95 respiratorโestablished strict cordon sanitaires along the Trans-Siberian lines, and converted empty freight cars into mobile quarantine wards. Facing frozen ground that prevented burials, Wu secured imperial sanction in January 1911 to cremate several thousand corpses across mass pyres, halting transmission and extinguishing the epidemic within four months.
Why today: This early enforcement of airborne infection control and quarantine protocols mirrors the public health protection challenges highlighted by the killing of an Ebola response nurse in the

Democratic Republic of the Congo.
