The influenza virus itself can lead to death if it leads to serious breathing problems and severe dehydration. However, the more common scenario is a complication from the infection, explains Dr. Claire Bocchini, an infectious disease specialist at Texas Children's Hospital.
She says bacterial pneumonia is the most common complication from the flu that leads to death.
"This happens because the flu virus injures the lungs and causes inflammation that then makes it easier for bacteria to invade the lungs and cause a very serious infection," Bocchini told CBS News. "The bacterial infection can make it hard for children to breathe, and their lungs struggle to get enough oxygen for their body."
While a few people seem to die within hours or days(部分患者于数小时或数天内死亡), flu can cause lingering sickness in others. Then they become susceptible to other infections, such as streptococcal or staphylococcal bacterial infections.
下面是cdc官方网站说的，大意是说，会引起全身炎症，多器官衰竭，然后很快死亡
Sinus and ear infections are examples of moderate complications from flu, while pneumonia is a serious flu complication that can result from either influenza virus infection alone or from co-infection of flu virus and bacteria. Other possible serious complications triggered by flu can include inflammation of the heart (myocarditis), brain (encephalitis) or muscle ( myositis, rhabdomyolysis) tissues, and multi-organ failure (for example, respiratory and kidney failure). Flu virus infection of the respiratory tract can trigger an extreme inflammatory response in the body and can lead to sepsis, the body’s life-threatening response to infection. Flu also can make chronic medical problems worse.
Flu can directly lead to death when the virus triggers severe inflammation in the lungs. When this happens, it can cause rapid respiratory failure because your lungs can’t transport enough oxygen into the rest of your body.
The flu can also cause your brain, heart, or muscles to become inflamed. This can lead to sepsis, an emergency condition that can be fatal if not immediately treated.
刚刚在网上做了些功课，总说美国流感也死人，那到底那些病人是怎么致死的，是什么症状？
看了之后，尼玛，感觉和新冠病毒没什么太大的区别
这篇报道说，流感会引起严重的呼吸困难，腹泻，而肺炎是并发症，导致死亡

再看一下新冠病毒患者的症状 （https://posts.careerengine.us/p/

在重症监护室的前两天，程亮的身体状况还算平稳，除了身上感觉酸痛、还伴随头疼、咳嗽、腹泻的症状。
监护过程中，程亮哪怕吃一点东西都会腹泻，后来发展到每天腹泻两三次。
1月26日当天，程亮病情突然加重，医生让他高流量吸氧，“感觉整个肺部就像一个打
满气的打气球，只能往外吐气，不能自主吸气。”护士都拿来了准备插管的器械。程亮的X光片显示，其双肺感染、唾液、鼻腔跟咽喉分泌物、血液、尿液及粪便中都查出病
毒。医生告诉他，他是目前在美国病例里发现最重的病人，证明病毒已经遍布全身，非常严重。当天晚上，程亮在手机上敲下给家人的遗书，他将遗书保存到邮件里，设置了定时发送的时间。
严重流感就是这样，都是相通的。李兰娟水平高就是因为在之前的流感重症治疗中积累了大量经验。
是的，都是Acute respiratory distress syndrome （ARDS）死的。 只是流感和新冠
到ARDS的转化率不同而已。
我觉得最终机理都差不多，病毒过度繁殖，导致身体其他功能失去应有的support，有
薄弱环节就被攻破了。
我小孩小时有一次得流感，你可以明显的感觉到病毒繁殖周期，退烧药都没啥用处，但周期一次比一次弱，到后来自己都能大概就估么着病毒快过去了。
cdc故意瞎搞，把那些癌症死的，其他疾病死的，只要近期有过流感，全都算到流感头上
据说cdc改标准前，美国每年流感死亡只有几百人，改了以后直接变几万了
美国现在流感病死率0.05%左右，依然比世界平均水平0.1%要好得多。按照美国的标准
，中国一年流感死亡将近九万人

新变异出现时死亡率高一些。社区化以后主要就是每年扫以前漏网的老头老太太。
