The number of infected people in Tokyo ended this week with the same number as the previous week …


I thought …but
today is Saturday, so when I calculate the total for the week … ↓



After all it has increased at all …



I think it was expected that this week would increase to some extent after the Bon Festival, but what will happen next week …
It’s going to be an important turning point for infection …





Meanwhile… How about the amount of people in the city in Tokyo…↓

*Currently, Japan is refusing to enter from India, Nepal, and Pakistan in principle as a countermeasure against Indian variant stain.


*Since the number of new infections in Tokyo seems to be almost the number of the previous day,

(Because the deadline for the number of new infections on the day is from 9:00 am the day before to 9:00 am on the day)





And also today, I will summarize some prefectures that have a high number of infected people, not just in the Tokyo area.

*Graph of the number of newly infected people in Japan as of yesterday

(* This bar graph is up to the previous day, so today’s red bar (handwritten) is on the far right, but it’s about this …)

(*4府県“宣言”追加 5道府県“まん延防止”適用を決定 政府 – NHK)
(まん延防止等重点措置 きょうから拡大 不要不急の外出自粛を – NHK)






↑It seems that Aichi Prefecture in the “Priority Measures for Prevention of Spread” area is also requesting the government to apply the state of emergency …

Infection status in Aichi Prefecture↓




So, it seems that the governors of the whole country are planning to recommend to the government, “Lock down now!” …!

“I can’t find any effect in the state of emergency”

“Requires consideration of measures such as lockdown many times”


Even if you think purely about the meaning of the words, it is unusual that the “state of emergency”, which should normally be used in a seriously dangerous situation such as “riot” or “war crisis”, but… now in Japan… it’s really meaningless…!



By the way, in such a situation … There was such data today!

Finally, data on the “effect of vaccination” has come out in Japan as well!


<Effect of vaccination on the number of infected people in Japan>


【Survey target】 57,293 people
         (=Number of infected people nationwide from August 10 to August 12)


【Result】 “Number of infected people who have completed vaccination”

*Number of new infections per 100,000 population
  Unvaccinated: 67.6 people
  1st time: 22.7 people
  Second time: 4.0 people


*Number of new infections per 100,000 population
 ・ Under 65 years old
   Unvaccinated: 69.7 people
   Second vaccinated: 7.4 people
 ·65 years of age or older
   Unvaccinated: 31.1 people
   Second vaccinated: 2.3 people


Basically it’s not very helpful, but … (dry laugh)
Well, it seems that the effect is coming out as it is!


(By the way … the reason why it is not so helpful)

①There are more people who have not been vaccinated yet, and the active younger generation (prone to infection) has hardly been vaccinated.
②The majority of people under the age of 65 who are vaccinated are “people who are vaccinated early because they are careful about infection control”.
③It is difficult to compare because the populations of vaccinated and unvaccinated people are different in the first place.




And the topic has changed … Yesterday and today, There is a hot topic that “to announce the name of the medical institution that does not accept COVID-19 patients”

While thinking, “No … there are various circumstances in the hospital …”
I started reading the news, but according to the article … the following facts were found.

「”The government subsidizes 170 medical institutions and 6000 beds in Tokyo with a maximum of 19.5 million yen as a” secured bed for COVID-19 measures “.”

“But it’s currently tight with a usage rate of about 3000 beds.”

“We think there are hospitals that receive only subsidies and do not accept COVID-19 patients.”

“When they actually interviewed the hospital, the acceptance record of that hospital increased after that.”


Hmm … I’m suspicious when I hear that …


What will happen to the result … I’m curious …!



By the way, it’s also been a little talked about recently,

The problem that “The test ability in Tokyo is actually 26,000 MAX, isn’t it?”


Various news sites have calculated that “the current positive rate is about 20%, so if 26,000 cases are MAX, the number of infected people is limited to 5,000?”


And alsoiIt seems that the Tokyo Metropolitan Health and Welfare Bureau also responded to the interview that “the number of inspections that can actually be performed per day is about 26,000.”





The data remains properly …

You guys haven’t tested 26,000 at all … why are you lying …


The tests at facilities for the elderly may be counted separately, but (as far as I can check), the highest number of tests in Tokyo is 24187.

Moreover, only one day.


By the way, even with my data …


Number of tests in Tokyo

(*What the Tokyo Metropolitan Government reports as “the number of tests 3 days ago” every day.
Actually, there are medical institutions that report late, and it seems that the number may increase by a little less than 1000 to 2000).


↑No matter how much it increases after that, the average number of cases per day will not be 26,000 …


By the way, a rough calculation shows that
the total number of tests is 254,463 in a total of 20 days from August 1st to August 19th,
with an average of 12,700 per day!

On the other hand, the number of infected people during that period is …
From August 1st to August 19th, the total number of infections is 83,481 in 20 days, and
the average daily number is 4,174!


That means … the positive rate is about 33% …
(Rather, it is a mystery how Tokyo gives a positive rate of 22% …)


And … If they can test 26,000 cases on Sundays, it seems that they can test about twice as much as the current average of 12,700 cases a day, so if the positive rate remains the same, the number of infected people will also increase double? About 8000 people!

Oh, 10,000 people have come into view!



… Hey … It’s about time someone stopped me …
I’m getting sick while calculating … lol



I don’t want to see the news that “10,000 people are infected today in Tokyo”!  🙁





And this article↓


How long time the materials such as paper, cloth, plastic, etc. need to eliminating the risk when coronavirus is attached, and how effective disinfection is.
If you are interested, please take a look!


Also, for “Does the vaccine work for mutant strains?”, See this table ↓

イギリス株やインド株にもワクチンは“90%以上有効”  – Youtube(MBS news)
ファイザー製ワクチン ブラジル株に効果期待 東大らのグループ – NHK

Is the vaccine effective against mutant strains? (*unit : %)
Number of vaccinations Conventional  British South african Brazilian California  NY Indian  Unknown 
Once 57 18 21 16 39 55 37 34
Twice 99 94 90 94 97 98 97 97





And here’s a trial calculation of how many people in Japan are actually receiving medical treatment.





(If it is exactly as announced)

For those who are undergoing medical treatment nationwide are…

these days it’s been declining significantly on most days, but…




In Kanagawa, the number of newly infected people per day has reached 3,000 …
Tokyo is also wandering around with 5000 people, but it can see 6000 people or not…


The number of infected people has increased considerably in various places, so I may summarize it tomorrow …


“The club of ‘2000 newly infected people’ is here!”

↑… Wow, this title … (dry laugh)






Please be careful when you go out!
