Dynamics of malaria outbreaks in the military: comparison of Paju and the Chuncheon weather station area. a: malaria patients in the military, 2006. b: malaria patients in the military, 2011. (a) Kaesong Industrial Complex began operating at the beginning of 2007. As a result, there might have been an influx of mosquitos carrying P. vivax malaria from north DMZ to Paju. (b), (d) Paju had been heavily influenced by northeasterly wind from 2006 to 2007, but its effects weakened between 2008 and 2011. As a result, transmission of P. vivax malaria by mosquitos from north DMZ to Paju might be contained. (c), (e) As Bukhan River might be a mosquito larvae reservoir, this might contribute to an increase in the number of malaria patients in the military around this area: malaria patients decreased in Cheorwon (c), and Inje (e), but otherwise malaria patients in the military increased in the Chuncheon weather station area (Hwacheon and Chuncheon)
