Covid-19 may also be much worse the second time around. During his first infection, my patient experienced a mild cough and sore throat. His second infection, in contrast, was marked by a high fever, shortness of breath, and hypoxia, resulting in multiple trips to the hospital.
Recent reports and conversations with physician colleagues suggest my patient is not alone. Two patients in New Jersey, for instance, appear to have contracted Covid-19 a second time almost two months after fully recovering from their first infection. Daniel Griffin, a physician and researcher at Columbia in New York, recently described a case of presumed reinfection on the This Week in Virology podcast.
It is possible, but unlikely, that my patient had a single infection that lasted three months. Some Covid-19 patients (now dubbed “long haulers”) do appear to suffer persistent infections and symptoms.
My patient, however, cleared his infection — he had two negative PCR tests after his first infection — and felt healthy for nearly six weeks.
…………
I am aware that my patient represents a sample size of one, but taken together with other emerging examples, outlier stories like his are a warning sign of a potential pattern. If my patient is not, in fact, an exception, but instead proves the rule, then many people could catch Covid-19 more than once, and with unpredictable severity.

群体免疫理想的前提条件：按美国3亿人口算，得至少2亿人染病+同时还得有足够免疫抗体+不考虑病毒变异。
目前距66%那群体免疫标准还差得老远呢，能获得抗体量和持续时间还都未知，。
就算这理论是真的，假设理想条件也都能成立，放任病毒横行肆虐，那得死多少人作为代价啊。
难道医学界找不到提高人体免疫力的方法吗？
始终认为，疫苗是弱化病毒让普通的人体免疫力学会战胜病毒；但是如果能够强化提高人体免疫力就可以让强化提高后的人体免疫力直接战胜病毒。我的这个想法有错吗？
好奇有没有人实践了你的方法来治疗新冠。
提高免疫力，没个指标怎么知道是否提高了。提高了，是否就能足够抗病？其实，细胞因子风暴可以说是免疫力强造成的。
历史上有练金钟罩的，据说刀枪不入。也许抗打击能力是强些，但能挡住子弹？
以前太过于侧重应激反应，应该说利用应激刺激是可以激活整个免疫体系的。
