how从句找错啦~how是主语从句。然后who从句的性质也有问题，句子翻译也是。……

For a social epidemic to occur, however, each person so affected must then influence his or her own acquaintances, who must in turn influence theirs, and so on; and just how many others pay attention to each of these people has little to do with the initial influential.

生词

• affected v. 被影响（动词的过去分词）；adj. 受影响的
• acquaintance n. 熟人
• in turn 反过来；依次
• and so on 等等
• pay attention to sb/sth 注意某人/某事
