After the conclusion of World War II, members of the Imperial Japanese Army biological warfare Unit 731 testified to a Soviet military court they conducted a live test deployment of plague-infected fleas in Ningpo, Zhejiang Province, a city south of Shanghai with a population of approximately 300,000. The deployment triggered an outbreak involving 78 cases and 74 fatalities (case fatality rate 95%) that included the death of seven families. Children and young adults aged 11-30 were most severely effected. Despite lack of access to effective medical countermeasures, the Ningpo community exhibited a high degree of social cohesion and resilience in the context of effective public health response.
