The COVID-19 pandemic has seen some Asian countries employ sophisticated mass-surveillance technologies—normally employed to gather intelligence for domestic security purposes—to contain the spread of infection in their populations. There has also been an intrusion of military and allied national security actors into the traditionally civilian domain of public health, in the form of disease surveillance. These emerging developments in the pandemic response provide a pretext for a limited historical review, beginning from World War II to the present, centred on the intersection between infectious disease surveillance and control, national security, and military in the Western world.
