如果家人感冒了，可以用英语说 "My family member has a cold." 感冒是一种常见的呼吸道感染，通常由一种叫做「冠状病毒」的病毒引起。
一些其他有关感冒的英文表达和中文翻译如下：
"My family member has a runny nose." (我的家人流鼻涕)
"My family member has a sore throat." (我的家人嗓子疼)
"My family member has a fever." (我的家人发烧)
"My family member has a headache." (我的家人头痛)
"My family member has a cough." (我的家人咳嗽)
如果家人感冒了，可以让他们喝热水，吃柠檬，或者服用感冒药来缓解症状。最重要的是，让他们多休息，以帮助身体恢复。
