"Why the narration of a mutant epidemic is unreasonable"
Currently, the media and modern medicine are noisy about the narration that the new coronavirus variant is prevalent.
Curiously, the first identified new coronavirus variant (B.1.1.7 SARS-CoV-2, α) in the United Kingdom quickly spread to Europe and North America, and is more contagious than the new coronavirus. It is said to be strong (Estimated transmissibility and impact of SARS-CoV-2 lineage B.1.1.7 in England. Science. 2021; 372 (6538) eabg3055).
Moreover, the infection mortality rate is also said to be stronger for this variant (Risk of mortality in patients infected with SARS-CoV-2 variant of concern 202012/1: matched cohort study. BMJ. 2021; 372: n579 ).
This cannot be the discipline of epidemiology.
As I mentioned in the lecture in March 2020, "strongly infectious ones have a low mortality rate. Highly infectious ones have a low infectivity" is at least the basis of real science. ..
High infectivity requires a high probability of transmission from a living person to a living person.
In this case, if the host becomes severely ill or kills due to infection, the chance of infecting the next host is lost.
Therefore, in order for the infection to spread widely, it is necessary to make it mild after infecting the host.
In other words, only those that can be cured with mild infection symptoms can be widely transmitted.
Those with a high mortality rate kill the host before it is widely spread to others.
Mild infectious disease = easy to spread (infected person moves around)
Severe infectious disease = difficult to spread (infected person is sick or died)
Just by connecting the published research papers (mostly fake (^ _−) − ☆), you can see that the mutant story is unreasonable (^ _−) − ☆.
