ABSTRACT
During World War II, members of the Imperial Japanese Army biological warfare Unit 731 conducted a live test deployment of plague-infected fleas in Ningbo, Zhejiang Province, China. The deployment triggered an outbreak involving 165 cases in downtown Ningbo, 112 of which were fatal (68% case fatality rate). Despite lack of access to effective medical countermeasures, the Ningbo community exhibited a high degree of social cohesion and resilience in the context of effective public health response. These findings support the value of community preparedness and strong public health infrastructure to mitigate the impact of biological weapons.

Dr. Wilson is a board-certified, practicing pediatrician who specializes in operational health security intelligence, with a focus on the anticipation, detection, and warning of infectious disease crises. He has led the creation of several of the most powerful systems in the world used for anticipation and detection of infectious disease crises and disasters. Dr. Wilson was the first operations chief of the Department of Homeland Security’s National Biosurveillance Integration Center and worked with the Intelligence Community during the birth of formal health security intelligence in the mid-2000s. Dr. Wilson led the private intelligence teams that provided tracking of H5N1 avian influenza as it spread from Asia to Europe and Africa, detection of vaccine drifted H3N2 influenza in 2007, warning of the 2009 H1N1 influenza pandemic, discovery of the United Nations as the source of the 2010 cholera disaster in Haiti, and several investigations of alleged and confirmed laboratory accidents and biological weapon deployments. Dr. Wilson is a strong advocate for effective and accountable global health security intelligence and the need for credible and balanced threat assessments.
