Once the authorities in Manchuria had secured a firm handle on the plague outbreak in Heilongjiang, Kirin and Fengtian provinces by February 1911, little time was wasted calling for a conference of international medical specialists to enquire into all aspects of the epidemic and promote the advancement of future disease control. Scientists including disease specialists from many countries were invited to attend the location chosen for the conference, Mukden (Shenyang), which was one of the cities in North-East China hardest hit by the pneumonic epidemic.

Despite the pressingly urgent need to canvas expert international input into the dire health catastrophe, China must have had some reservations about what it was doing. Both Russia and Japan with undisguised Manchurian ambitions already held firm footholds in N.E. China (control over railway lines, ports, territorial concessions, etc), plus other Western powers controlled Chinese treaty ports further south. But with no politicians taking part in the conference and all attendees pledging that it’s focus was to be on scientific investigation and not about imposing any further external controls on China, the central government pushed on with it [‘In 1911, another epidemic swept through China. That time, the world came together’, (Paul French), CNN, 19-Apr-2020, www.cnn.com]. Dr Wu Lien-teh, the “plague fighter-general” of Harbin, was appointed conference chairperson. There were a few “nationalistic frictions” with the Japanese mainly resulting from some anti-Chinese remarks injudiciously made by the Japanese delegate, Professor Kitasato, before leaving Tokyo for the conference, but this did not impede the cohesion of the conference  [Eli Chernin (1989). “Richard Pearson Strong and the Manchurian Epidemic of Pneumonic Plague, 1910—1911” (PDF). Journal of the History of Medicine and Allied Sciences. 44(3): 296–319. doi:101093/jhmas/44.3.296. PMID 2671146].

A congress of international disease experts
The International Plague Conference (IPC) was a ground-breaking series of ‘firsts’, the first international scientific symposium held in China, the first time in modern history of a multi-nation approach focusing on disease control. The conference also anticipated the purpose of later world bodies dedicated to international health maintenance, the League of Nations’ Health Organisation (LNHO), established in 1923, and  it’s successor, the UN’s World Health Organisation (WHO), created after the Second World War.

Scientists from ten countries joined host China at the Plague Conference in the repurposed Shao Ho Yien palace – the US, UK, France, Russia, Japan, Italy, Germany, Austro-Hungary, Netherlands and Mexico, an indication of how seriously the international medical community took the Manchurian outbreak and its implications. The delegates were drawn from several relevant and related fields including epidemiologists, virologists, bacteriologists, tropical medicine specialists and illness consultants.

The conference, getting into the “nitty-gritty’ 
High on the conference’s agenda was the question of aetiology, what were the Great Manchurian Plague’s causal factors? American delegate Richard P Strong, who arrived prior to the conference, undertook pathological experimentation which verified the infectious role played by tarbagan marmots in the plague (which he published in the Philippine Journal of Science, 1912). The experts had to sift through a raft of unhelpful faux-scientific beliefs and assumptions to get to “the scientific root of the bacteria”, again underlining the IPC’s emphasis on science and medicine. Containment was another key issue at the conference. The discussion was around what worked best in the plague? Measures like ‘blanket’ quarantines, travel bans, face masks and ad hoc plague hospitals (swiftly assembled to isolate the infected from the healthy), all got a big tick…an endorsement of Dr Wu Lien-teh’s positive measures in the war against the pneumonic epidemic, deemed by the conference delegates as essential tools in the fight against future outbreaks and waves of plague (French).

🔺 The admirable Dr Wu

Seeds of a nationwide public health service 
One of the conference’s finest and far-reaching achievements was to establish the Manchurian Plague Prevention Service (under the helm of Dr Wu). The MPPS and Wu identified medical education as the “holy grail”, the service’s role was to  disseminate materials to the public, promote the efficacy of sanitary conditions and health in the community, and overall playing a leading role in adopting Western medicine (Xīyào) and methods of disease control in China. MPPS provided the model for a future Chinese national health service (French).

The follow-up to the three-and-a-half week International Plague Conference put Chinese medicine on the path to modernisation. Many of the country’s medical advances began here …. the IPC laid down a blueprint for handling future plagues which included the use of autopsies,  instructional dissection and cremation, all of which became institutionalised practice afterwards (Chernin).

Medicine and health before politics
The Mukden IPC in April 1911, conducted in an atmosphere free of politicising, demonstrated the cooperative humanitarian efforts of a group of medical professionals…when left to it by the politicians, they showed single-minded unity of purpose, what could be achieved, collectively and internationally, to counter the danger of a disease with immediate and future global ramifications for public health. I need not emphasise the stark contrast with the management of the world’s current pandemic in which some of the major powers, distracted from the only really important priority, are happy to engage in a ”political blame game” over the coronavirus‘ origins, instead of co-operating with each other to meet a pernicious and deadly health risk to the planet head-on and in unison.

Endnote: Lessening future shock
The gains in medicine and public health protection coming out of the conference were soon put to use in China. Disease re-emerged in the 1919 malaria epidemic and the 1921 plague (again in Harbin) which was to test China’s embryonic national quarantine system. Dr Wu again took charge to guide China through these medical crises. The improvements in public health since 1911, it is estimated, reduced casualties in the second outbreak of pneumatic plague by four-fifths [‘Portraits of a plague: the 19th-century pandemic that killed 12 million people’, History Extra, 21-Jul-2015, www.historyextra.com].
