Nevada lab confirms 1st coronavirus reinfection in the US.
https://abcnews.go.com/Health/nevada-lab-confirms-1st-coronavirus-
reinfection-us/story?id=72691353
A 25-year-old Nevada man appears to be the first documented case of Covid-19
reinfection in the United States.
The patient was first diagnosed with coronavirus in April after he had a
sore throat, cough, headache, nausea and diarrhea, the researchers wrote in
a pre-print study posted Thursday. He got better around April 27, and he
tested negative for the virus twice afterwards.
He continued to feel well for about a month. Then on May 31 he sought care
for fever, headache, dizziness, cough, nausea and diarrhea. Five days later,
he was hospitalized and required ongoing oxygen support. He was tested
again for Covid-19 and the results were positive.
这个内华达的第二次感染症状加重需要吸氧治疗。
香港一名33岁男发现了首例有记录的冠状病毒再感染病例，第二次没有明显症状。
看Nevada 和香港的病例，这难道是拼运气吗？
最怕的是像当年的西班牙流感一样，第一轮好像没啥，第二轮变异病毒一来，那些之前
感染过的症状轻的患者（有微量抗体，反而介导病毒攻击人类细胞），在二轮三轮病毒
之下，排山倒海的死亡啊。
疫苗是不是也很危险？怎么给那些接种过疫苗的受试者以不同strain的新冠病毒呢
challenge？接种疫苗产生的抗体可能会对某种新冠有效，但对变异的新冠反而是特洛
伊木马，帮助病毒侵害其他人体细胞？
这个文章真是大家要读一读

不戴口罩的川粉川黑感染了，以为有抗体一切大吉，殊不知这个RNA病毒变异快，ADE现
象一出，就自求多福吧！！！！！！！！！！
还有
SARS 病毒疫苗在前两年的动物灵长类实验，给动物再感染病毒，有明显的ADE 抗体增
强效应（这可能是致命的），这个新冠根本就不是流感病毒可以企及的呀，还流感疫苗
水平??????
你觉得你还那么乐观吗 | m*x

was infected and found that the viruses had differences in some of their
genes, caused by natural mutations.
这个内华达的前后两次感染的是 不同毒株 的新冠病毒

发帖数: 202 | 5 做到尽量不被感染，戴口罩，保持社交距离，勤洗手注意卫生。
靠人口数量啊，自然界自然会完成余下的脏活。
