常见误用提醒

使用 coinfection:He has a coinfection of virus. → He has a coinfection with a virus. (错误在于使用了'of',而正确介词是'with',用于表示感染的具体病原体。)

使用 coinfection:Coinfection means infection again. → Coinfection means simultaneous infection with multiple pathogens. (错误在于将'coinfection'误解为'再次感染',实际上它指'同时感染',强调多种病原体在同一时间感染。)

使用 contagion:The contagion is very dangerous, we should avoid it. → The contagion is very dangerous; we should avoid exposure to it. (错误在于将contagion直接作为可避免的物体。正确用法应说明避免的是接触或暴露于传染源,因为contagion通常指抽象传播过程或影响。)
