Comments on the Discovery of Insects in the Suburbs of Fushun[1]

(4 March 1952)


Premier Zhou [Enlai]


Prepare injection vaccines for all soldiers and civilians in Liaodong and Liaoxi Provinces. Eastern and Central Hebei, as well as Beijing-Tianjin, should also make preparations. Please report if there are enough vaccines for this.


Mao Zedong

4 March [1952]


[1] This comment was written on Information no. 15 from Shenyang on 3 March.  The Information said that at 5 p.m. on the afternoon of 2 March the Northeast Military District Health Department received a report from the Division of Public Security that a division station seventy li south of Fushun in Beidagou found a large number of insects. [The division] immediately dispatched inspection personnel to collect specimens. According to the investigations, this area had a large number of flies, spiders, and fleas, as well as an unidentified black bug with a group-like distribution. According to the office responsible for epidemic prevention, US forces in Korea spread bacteria two ways, with bombs and in bags. The flies and spiders found in Fushun were probably spread using the latter method. The Northeast Military District Health Department dispatched a 30 person epidemic prevention team to work with the local government organized epidemic prevention committee in carrying out disinfection and quarantine the abovementioned areas south of Fushun.
