Until the 1950s, Ascaris was regarded as an essential part of life which controls every aspect of human physiology among Koreans. Therefore, Ascaris should not be removed from human body. Efforts from medical professionals and the Korean government officials who wished to push forward the parasite control program, had to constantly contest with this perception of Ascaris among ordinary Koreans. In 1966, the 'Parasitic Disease Prevention Act' was promulgated and 'the Korean Association for Parasite Eradication (KAPE)' established in Korea. From the 1970s, Korea mobilized 15 million people each year to achieve the eradication goal. Such mass mobilization could not be possible without public awareness on necessity of parasite eradication. Until the early 1960s, however, Korean people were not sympathetic to the needs of eradication of parasites, especially that of Ascaris. Then, what changed the social perception towards Ascaris during the 1960s? What contributing factors allowed the mass mobilization and public involvement for that campaign? Employing newspaper articles and periodicals, this paper analyzes how social perception on Ascariasis changed during the 1960s, when the 'Parasitic Disease Prevention Act' was established. During the 1960s, Ascariasis became a shameful disease for Koreans. A series of events made Ascariasis more visible and shameful to Koreans. First event happened with Korean miners who were dispatched to Germany in 1963. When the miners turned out to have been infected with intestinal parasites, they were prohibited from work at the mines by the authorities in Germany and quarantined for several weeks. This humiliating experience of Korean expatriate people having bodies swarmed with parasites became a national shame to Koreans. The parasite infected bodies of Korean workers were revealed to the World through German newspapers. Second event happened when a child died of intestinal obstruction due to Ascariasis. The doctor retrieved 1,063 Ascaris from the bowel of the 9 year-old girl, and the photo of the 1,063 worms was published in several newspapers. It was a shocking visualization of Ascariasis in Korean society. Through these visualizations of Ascariasis, the Korean society began to perceive Ascariasis as a shame of the nation as well as that of an individual.
The Korea Association of Health Promotion and Japanese Organization for International Cooperation in Family Planning (JOICFP), and Taiwan's Chinese Foundation of Health all originated from parasite control organizations. Currently these organizations hold no apparent relations to parasite control activities. However, many of the senior leaderships of these organizations including presidents, have parasitology as their background. Kunii Chojiro (the founder of Japan Association of Parasite Control (JAPC) and JOICFP) explained it as "it all started from worms." In 1949, Kunii Chojiro established JAPC after personally experienced intestinal parasite infection. The JAPC people conducted mass examination and mass chemotherapy focusing on school children, which allowed them to have sustainable income. In 1965, the Korea Association of Parasite Eradication (KAPE) requested JAPC to assist Korea's parasite control activity. In 1968, when Korea-Japan cooperation for parasite control activity established, Japan's operating procedures were directly absorbed by KAPE. With support from JAPC and official development aid through Overseas Technical Cooperation Agency in Japan (now Japan International Cooperation Agency), Korea successfully controlled parasite infection. Post-war and cold-war geopolitics had a significant impact on Korea-Japan cooperation. In 1960s the president of KAPE, Chong-Chin Lee and Kunii Chojiro were well known figures in population control network. They did understand the importance of population control, but did not agree with the approaches taken by western population control experts. From their point of view, it had to be self-initiated, economically self sustainable grass-root activities rather than top-down activities, as experienced in their parasite control in Japan and Korea. This lead to a new Asian model named "Integrated Program". Together with their influence in population control network, Kunii and Lee manage to secure the fund from IPPF. Emergence of Integrated Program showed how collective experience of Asia, as well as overlap of networking formed 'Asian Model' of public health activities. Kunii and Lee shared the same agenda to enable people to have better life through public health measures. While they funneled money from global population control network, they were more interested in securing sustainability of the parasite control activities. This paper focuses on activities and experiences of Kunii Chojiro and Chong-Chin Lee to show interplay of Cold War geopolitics in Asia led to emergence of Asian network.
DDT exemplifies success and failure of modern science and technology. Once it was heralded as technological wonder that will deliver human from misery of insect-borne infectious disease. However DDT took dramatic downturn after failure in global malaria eradication program initiated by World Health Organization, with advent of DDT-resistant strain of mosquitoes. Although insecticide resistance has been know since late 19th century, the definitions and mythologies for finding resistance has not been settled until 1950s. This paper argues that discovery of DDT-resistant strain of body lice in prisoners of war camp in Korea during the Korean War provided essential knowledge and opportunity for advancing insecticide resistance studies.</br>Since 1945 to the end of Korean War, US Army sprayed thousands of tonnes of DDT on Korean body and soil. DDT was only went into wide field application since 1943, was still a very new technology. The ways to deliver and utilize DDT was still under the investigation. And Korea, especially during the War, was ideal place to construct such knowledge and place it in the application. The main focus was to control public health threats, such as louse-borne typhus fever. Korean soldiers and prisoners of war exposed to regular dose of DDT, which soon gave rise to DDT-resistant strain of body lice. It was the first major outbreak of insecticide-resistance appeared in insect that has major public health importance. Until early 1950s, mechanisms of resistance, or even definition of insecticide resistance was unclear. Researchers in US Army and Department of Agriculture rushed to find the ways to quantify insecticide resistance. Network of laboratories, connecting Korea-Japan-US, had to devise new laboratory methods to rear, and test body lice. These body lice later migrate to laboratories in US, providing valuable asset for future insecticide resistance research in US. At the same time, laboratory methods of testing resistance in body louse became a standard across the globe, setting new research agenda through World Health Organization. This shows flow of knowledge, along with migration of body louse, during the Korean War. At the same time, this case show who new knowledge is constructed through the expense of involvement of minority populations, such as natives, soldiers, and prisoners of war.
