Picture something alive and far too small to see getting inside the body and starting to multiply there. The word covers both halves of that picture — the getting-in, and the trouble it causes once it is in. Which half you mean depends on the sentence, not on a different word.
可以想成：某種活的、小到看不見的東西進到身體裡，開始在裡面繁殖。這個字同時涵蓋這個畫面的兩半——「進去」這件事，和進去之後造成的那個麻煩。至於你指的是哪一半，靠句子決定，英文並沒有換字。
