For centuries, the Korean peninsula was a major endemic area of Paragonimiasis. North Korea, which had many major endemic foci, focused on the eradication of Paragonimiasis since the early days of na- tion-building. During the period of the first economic development plan, Paragonimiasis became one of the main obstacles for the development of North Korea, as it degraded labor power. In 1995, North Korean para- sitologists adopted the “Devastation” method from the USSR. This was “aggressive prevention through attacking and eradicating every possible de- velopmental stages of parasite from egg, larvae to adults.” Completion of the agricultural cooperative and the socialist economic system in 1958 al- lowed mass mobilization in the rural areas. North Korea conducted an in- tensive eradication effort through mass mobilization of women and students. They captured dozens of tons of intermediate host snails and car- ried out comprehensive hydrotechnical engineering projects on the river ecosystem. Paragonimiasis prevention dispensaries were established in each village to provide mandatory treatment to residents. As a result of this pro- gram, North Korea declared the eradication of Paragonimiasis in 1961. This program, implemented during the socialist nation-building period, was not only a socialist remodeling of the production system and people’s ideology, but also a wider remodeling of the ecosystem that provided the physical basis for socialist life.
