The disease is mostly transmitted through the bite of an infected tsetsefly but there are other ways in which people are infected with sleeping sickness.
疾病主要通过受感染采采蝇的叮咬传播，但也有其它途径可使人感染昏睡病。

Rural populations living in regions where transmission occurs and which depend on agriculture, fishing, animal husbandry or hunting are the most exposed to the tsetsefly and therefore to the disease.
生活在发生传播的地区并依赖于农业、渔业、畜牧业或狩猎业的农村人口最有可能接触采采蝇并因此接触该病。
