這是一個大家都關心的問題:無症狀新冠感染者安全/危險嗎?
最近傳出一個YouTube 視頻:

美國德州一位有名的心髒醫生兼教授,Dr. Peter McCullough在州衛生部門的聽證會上大力提倡新冠患者的
如果M醫生/教授的發言就此停止,那將是一個很好的見證。
M教授的發言,如果我不是再聽三遍,連我自己都覺得被容易誤導。
可是M教授並沒有停止,接下來又多加了一點更有爭議的陳述:

presymptomatic and asymptomatic infections contribute together to at
least 50% of the overall force of infection.

In this cohort study that included 303 patients with SARS-CoV-2 infection isolated in a community treatment center in the Republic of Korea, 110 (36.3%) were asymptomatic at the time of isolation and 21 of these (19.1%) developed symptoms during isolation. The cycle threshold values of reverse transcription–polymerase chain reaction for SARS-CoV-2 in asymptomatic patients were similar to those in symptomatic patients.
注:reverse transcription–polymerase chain reaction=RT-PCR (一種檢測病毒的定量方法).

CDC researchers discussion:
Overall, the model predicted that 59% of coronavirus transmission would come from people without symptoms, including 35% from people who were pre-symptomatic and 24% from those who never showed symptoms at all.
"無症狀感染者"本身是一個不太嚴格規範的名詞。
M教授提出的所謂"早期介入治療",主要是抗炎,防止並發症,防止血栓形成。藥物如激素,colchicine, 抗凝藥。沒有特異的抗氧化病毒藥。按他的話說,防止惡的有效率達50%。他們有文章發表的。
他沒有解釋50歲以下沒有基礎病人群無需接種的理由。可能是身體健康,死亡率少,而自然感染後免力最強吧。
他所指的80%群體免疫,是否包括接種+自然感染的免疫率?
早期症狀輕微,你治療什麽?治療症狀還是治療病毒?
去年全美因病死亡人數比平均年份高很多嗎?如果有,高多少?如果沒有,為什麽要沒完沒了的說這事呢
50歲以下沒有基礎病的人無需疫苗接種的理由是什麽?
7月15日為止,全美國完成注射疫苗的人是48%,德州是42%。不是文中說的德州有80% 的群體免疫。
