The anti-plague system and the Soviet biological warfare program.

The USSR possessed a unique national public health system that included an agency named "anti-plague system." Its mission was to protect the country from highly dangerous diseases of either natural or laboratory etiology. During the 1960s, the anti-plague system became the lead agency of a program to defend against biological warfare, codenamed Project 5. This responsibility grew and by the middle 1970s came to include undertaking tasks for the offensive biological warfare program, codenamed Ferment. This article describes the anti-plague system's activities relevant to both aspects of the Soviet Union's biological warfare program, offense and defense, and analyzes its contributions to each.
