Disease surveillance is not adequate to detect cases of sylvatic yellow fever that often occur in remote areas. 疾病监测不足于检测到常发生在偏僻地区的丛林黄热病病例。
Sylvatic ( or jungle) yellow fever: In tropical rainforests, yellow fever occurs in monkeys that are infected by wild mosquitoes. 森林型(或丛林型)黄热病:在赤道雨林中,黄热病发生在被野外蚊虫叮咬而受感染的猴子身上。
Mosquito control programmes targeting wild mosquitoes in forested areas are not practical for preventing jungle ( or sylvatic) yellow fever transmission. 在预防丛林型(或森林型)黄热病传播方面,以林区中野外蚊虫为目标的蚊虫控制规划缺乏可操作性。
