For example, last year China and Egypt announced the elimination of lymphatic filariasis, a disease that currently disables some 40 million people.

例如，去年中国和埃及宣布丝虫病，这一疾病目前使约四千万人成为残疾。

Filariasis happens when one of these nematodes gets in the lymphatic system and causes a bit of fibrosis, which creates a physical blockage that obstructs the normal flow of lymph.

当这些线虫进入系统，并引起轻微纤维化后，就会导致丝虫病，进而造成物理性阻塞，阻碍正常流动。

One of the most common global causes of lymphedema is filariasis, an infection with nematode parasites, which are tiny worms; the most common species are: Wuchereria bancrofti, Brugia malayi, and Brugia timori.

丝虫病是水肿在全球范围内最普遍病因，为线虫类寄生虫感染所致；最常见物种有班氏吴策线虫、马来布鲁丝虫与帝汶布鲁丝虫。
