疟疾传播不仅在村庄与村庄之间不同,即使同一村庄不同的家庭也不一样。为了了解引起儿童疟疾发病的家庭高危因素,作者于1997年在海拔1 800—2 225米的埃塞俄比亚北部Tigrey地区选择了8对村庄作为调查对象,进行了研究。 Malaria spread not only between villages but also between villages, even though different families in the same village are different. In order to understand the high risk of family-based illness that causes childhood malaria in the country, the authors selected 8 pairs of villages from Tigrey, northern Ethiopia, at an elevation of 18,500-2,225 meters in 1997 as their research object.
