voice 1: But the medicine does not fix the problem fast. The medicine cannot kill the adult worms living in a person's body. A person with filariasis must wait for the adult worm inside her to die. This may last six years! And making sure that everyone in a community takes their medicine can be difficult. Medicine also costs a lot of money. Most people in these poor villages cannot buy it.
声音1：但是药物不能快速解决问题。药物无法杀死寄生在人体内的成年寄生虫。丝虫病患者必须等待体内的成年寄生虫死亡。这可能要持续6年的时间！确保社区中所有人都服用药物可能很难。而且药物也会花费一大笔钱。这些贫穷村庄的大多数人负担不起药费。
