This study was conducted in KR2 along the China-Myanmar border in a hilly and forested area with a tropical rainforest climate (Fig. 1). The total population is about 60,000 and most of them are Kachin Ethnic Minority (known as Jinghpaw in China). In KR2, hot weather, pluviosity, and a dense forest facilitate the breeding and development of anopheline mosquitoes. Malaria vectors are complex, and the primary vectors are Anopheles dirus and Anopheles minimus. Malaria transmission occurs the whole year, but the peak occurs during the rainy season from May to November each year. During that time, Plasmodium falciparum, Plasmodium vivax, Plasmodium malariae, and Plasmodium ovale are all prevalent [8 ]. In the region, malaria control programmes are generally provided by international non-governmental organizations (INGOs).
