I'm back home today to accompany my mother for her treatment.

This year, I couldn't go back home for New Year's, Golden Week, or summer vacation, so this maintenance of my parents' house (mainly weeding the garden) is going to be a big deal.

Last summer, I took more than enough measures to prevent heat stroke, and yet, I still had the early symptoms of heat stroke.

This time, I'll make sure the bath tub is filled with water and get on with the garden maintenance.

As with last year, residents of the Tokyo metropolitan area are not welcome in any part of the country.

However, at present, I am honestly "scared" to move outside of the Tokyo metropolitan area.

The infectious power of the mutant strain (Delta strain) is so great that I am frightened.

I think the majority of the population, with the exception of a few people, has implemented a basic response to the new coronavirus.

According to my rough calculation, the infectivity of the initial new coronavirus is 1500 times higher than that of influenza (since the incidence of influenza in 2020 was 1/1000).

The mortality rate compared to influenza is more than 40 times higher (some estimates put it at 100 times higher).

However, the infection rate of the delta strain is more than twice as high as that of the initial new coronavirus (it can be calculated to be 4.5 times higher).

In addition, there are reports that vaccination (Pfizer) is only 43% effective in protecting against infection.

I have already completed two vaccinations, but my alertness is higher than last year.

I don't plan to talk to my sister or mother, let alone my relatives, during this trip home.

I'm planning to devote myself completely to "the maintenance of my parents' house by myself + my mother's treatment assistance".

In my previous column, I mentioned that "eventually it will weaken" -- and of course, I'm sure I'm not wrong -- but in the very short term of one year, it is becoming "horribly poisonous.

I believe that one of the reasons for the increasing virulence of this virus is the "vaccine offensive" from the human side.

"Billions of people around the world are being inoculated with a vaccine that has a 95% protection rate against infection, an unprecedented level of efficiency in human history. From the viral side, this would appear to be an unprecedented war of annihilation by hostile forces.

The new coronavirus should be regarded as having given up its strategy of coexisting with human beings through "weakening" and has turned to a "strengthening" strategy.<
