I’ve been looking at disease patterns in the early stages of the USAMGIK occupation, focusing on the cholera outbreak of spring and summer 1946, covering roughly April to September of that year, and peaking with the summer rains in June and July. I’m still not certain that a single disease identity is the correct frame, as there was some question of translation in the Japanese context–this according to Crawford Sams, with GHQ PHW (Public Health and Welfare)–and a number of competing disease entities as well, typhus primary among these.
In any case, leaving the question of identifying a disease entity aside for the moment, the patterns of quarantine and policing established by both USAMGIK and GHQ contain numerous interesting overlaps with previous policy. For one, the movement of repatriated ethnic Koreans back to Japan for a variety of reasons in 1946 and 1947–family property left behind, seeking to return to work in Japan, allegations of black market activity–meant that this group, along with Taiwanese, rapidly became identified with the disease itself in the Japanese press. There’s already a good bit of scholarship on this point–e.g., both Tessa Morris-Suzuki and Christopher Aldous have published on migration controls and disease policy (typhus) in Japan–indicating that the outbreak of cholera tended to reinforce existing prejudices and beliefs about ethnic Koreans.
Within Korea, the disease created the conditions for a mobilization based upon the introduction of “Western” medicine to a greater extent than had previously existed. That is, food controls, restrictions of the use of “night soil,” controls over sources of potable water, survey of animal populations, and even restrictions regarding large public gatherings (including funerals) were all among the practices put into effect to try to limit the spread of cholera, generally passed along by contaminated food or water sources. I have yet to find any local medical records (still working largely from USAMGIK bulletins here and Korean newspaper accounts), but it’s fair to speculate that this general policy felt a lot like Japanese policy regarding public health for much of the 1920′s and 1930′s. And the use of “local area doctors” (USAMGIK’s term for certain groups of TKM practitioners, although again, the translation issue is not always clear) meant that practitioners of traditional Korean medicine were enrolled as a last line of defense in terms of reporting the spread of disease. As both Park YunJae (Yonsei) and Shin Dong-Won (KAIST) have written about the reliance upon traditional practitioners fifteen to twenty years earlier, there’s considerable room here for speculation about how these new policies were received.
Finally, the disease did not respect boundaries, and two further problems added to the complex situation. One, the movement of Japanese forces and ethnic Koreans, primarily from North (Manchuria) to South (the DMZ, with some destined for Pusan) across the border rendered the migrations controls ineffectual. This was also the case for Southern Japan, where individuals could cross by boat into Japan unorbserved. Two, the lack of reliable information and communication with the Russians / Northern representatives only exacerbated the situation.
I still don’t know exactly what to do with this information collectively, except to note that it has a lot to do with the “national style”–itself a problematic label–that South Korea would later adopt with respect to medical practice, and to recognixe that the polciing aspect of public health definitely continued beyond the colonial period into the occupation and the subsequent formation of new states.
