Infected

“Infected” 表示人或物“已被病原体感染”,如 infected wound(感染的伤口)、infected patients(受感染患者)。也可引申为文件、系统“被病毒入侵”,如 an infected computer。

  1. “The cut became infected and needed medical treatment.” (伤口感染了,需要医疗处理。)
  2. “Several staff members were infected during the outbreak.” (疫情暴发期间有几名员工被感染。)
  3. “Do not open the file if your device is already infected.” (如果设备已被感染,不要打开该文件。)

“Infected” 来自拉丁语 “inficere”(放入、污染),由 in-(进入)与 facere(做)组合,原义是“把有害物质放入”。

“in-” 表示“进入”;“-ed” 为过去分词后缀;词干 “fect” 与 effect、defect 等同源。

在公共卫生、网络安全和医学新闻中,“infected” 是高频词,常与 virus、bacteria、malware 等搭配。

  • 固定搭配: “infected with” (感染了……), “infected area” (疫区), “infected file” (受感染文件)
  • 原形: infect
  • 名词: infection

“in + fect + ed”:有害物质已经“进入”并起作用,所以是 infected。

“The nurse checked every infected patient carefully before the ward was fully cleaned.” (在病房彻底清洁之前,护士仔细检查了每一位受感染的患者。)
