Find the patients, isolate them, find their contacts, track them, and make sure infection control is done meticulously.

将感染者隔离，找到同他们接触的人，追踪这些人的情况，确保仔细完成感染控制的工作。

Countermeasures such as isolating the sick and tracking contacts of those infected have been hard to establish in countries where Ebola was unknown until this outbreak.

如隔离病人及对感染者追踪等的应对措施在这些埃博拉疫情才为人所知的国家一直并没有用武之地。
