参考译文
普通感冒、流感和新型冠状病毒
流感和普通感冒都是呼吸系统疾病，但它们是由不同的病毒引起的，因为这两种疾病有相似的症状，单凭症状很难区分它们。一般来说，流感比普通感冒更严重，症状也更严重，感冒比流感温和不会导致严重的健康问题。
流感的紧急警告信号是什么？
儿童
◆ 呼吸急促或呼吸困难
◆ 胸部疼痛
◆ 严重肌肉疼痛（孩子无法走路）
◆ 脱水（8小时无尿，口干，哭时无泪）
◆ 癫痫
◆ 体温40摄氏度以上
◆ 发热或咳嗽症状有所改善但会复发或恶化
◆ 慢性疾病恶化
成人
◆ 呼吸困难或呼吸短促
◆ 持续头晕或胸腹部压迫
◆ 癫痫
◆ 无尿
◆ 严重的肌肉疼痛
◆ 严重的虚弱或不稳定状态
◆ 发热或咳嗽症状有所改善但会复发或恶化
◆ 慢性疾病恶化
出现这些警告信号的人应该立刻就医。流感和新型冠状病毒有什么区别？
COVID-19是由一种新型冠状病毒（称为SARS-CoV-2）感染引起的，而流感是由流感病毒感染引起的。COVID-19似乎比流感更容易传播，在一些人身上引起更严重的疾病。需要更长的时间才会出现症状，而且感染的时间也更长。预防感染的最佳方法就是避免接触病毒。当然，接种新冠疫苗是首要。
相同点：
◆ 发烧或感觉发烧/发冷
◆ 咳嗽及喉咙痛
◆ 呼吸急促或呼吸困难
◆ 疲劳
◆ 肌肉或身体疼痛
◆ 有些人可能会呕吐和腹泻，但这在儿童中比在成年人中更常见。
区别：
流感：常见体征和症状如上所述。
新型冠状病毒：
◆ 发烧或发冷
◆ 咳嗽
◆ 呼吸急促或呼吸困难
◆ 疲劳
◆ 喉咙痛
◆ 肌肉或身体疼痛
◆ 鼻塞或流鼻涕
◆ 失去味觉或嗅觉
◆ 恶心或呕吐腹泻
老年人或患有心脏病、肺病或糖尿病等严重下属疾病的人似乎更有可能因COVID-19 疾病而出现更严重的并发症。症状可能在接触病毒2—14天后出现。
这并不是所有可能的症状，如果有任何其他严重的或与您有关的症状，请拨打120或提前到您当地的应急设施。
