Well, the last few days have been full of news about elections, and COVID-19-related topics have been pushed into the corner …


First of all, I will introduce some news that I was interested in!

“Foreign matter contamination” in the vaccine container of Moderna has become a big problem, but the following was announced about the foreign matter in the container found in Kanagawa!

“Rubber stopper fragments that are rarely mixed in during the manufacturing process”

“Vaccination is an intramuscular injection, not a blood vessel, so there is no risk of clogging the blood vessels.”

… But as usual, the results of the investigation on foreign substances that seem to be metal pieces have not been released yet, so I’m still curious about that …!



In addition, the infection has spread too much in Hyogo prefecture, and it seems that the investigation to close contacts will be reduced …

Until now ↓

Health center confirms the behavior of infected people
 → Contact the business operator and track if there are any close contacts

From now on ↓

Leave part of the follow-up survey of close contacts to businesses etc.


It sounds good to say, “We leave part of the follow-up survey of close contacts to businesses, etc.”, but the point is, “The health center doesn’t know any close contacts anymore! If you’re scared, do your own research!”, right?



And … a variant strain is coming out again…!

This time, “μ(mu) stock confirmed in Colombia in January this year” seems to be dangerous …

Apparently, “there is a risk of vaccine resistance”


The recently talked about “Lambda strain” was also from South America, right?
After all, when the infection spreads super-expands, it becomes easier to mutate ..


Hmm …? Tokyo and Japan may be also dangerous …



So, there wasn’t much news today, so I’d like to introduce some of the data I wanted to summarize!


Always like this at the above↓

I have introduced the infection status by age group, but has the proportion of people in their 20s and 30s decreased recently?


Looking at SNS etc., it seems that some people have noticed …


It looks like this when I actually graph the transition of the ratio of people in their 20s to 30s

↑t peaked around 60% around the end of July and has fallen by more than 10% …!


“Late July”…?
It means that the ratio continued to decrease during the 5th wave period …!




The answer may be here …! ↓ (Infection rate of each generation in Tokyo)

It’s a little too big and cluttered, so it’s hard to see, but if you look closely, most generations are “flat”, but the top yellow-green “20’s” has begun to fall after the end of July, and on the contrary, the percentage of “under 10s / teens” indicated by the red arrow is gradually increasing …!


The starting point for both of them is late July … It’s more like “summer vacation” than “consecutive holidays” …


Finally … I made a graph for each generation by “number of people”, but

↑ Overall, it has the same “shape”, but the number of people in their twenties is increasing and decreasing abnormally, so it seems that the proportion of people under the age of 20 and those in their 60s and over, whose increase and decrease is gradual, will increase when the infection subsides …!


Young people in their twenties play too much in the summer …


Of course, there are many people in their twenties who are refraining from going out etc. and taking care to prevent infections!


And as far as the ratio is seen …
It seems that the number of infections for children under the age of 20 has not decreased as expected
(Not as good as other generations)
so the new semester will start, so I’m a little worried …






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…




Today I have compiled the data for the first time in a while, but then the current number of patients in Tokyo is like this! ↓

↑Although it has finally begun to decrease, there are still 35,000 people …


Speaking of 35,000 people … Tokyo has a population of about 14 million, so…
…1 in 400 patients with COVID-19? !!


Will the number of patients continue to decrease to about 5,000 before the spread of the infection, or
will the spread of hell infection begin from autumn to the year-end and New Year holidays like last year…
Since the government does nothing in Japan, we are in a state of “leaving ourselves to the natural flow regarding the infection situation”, so we are quite anxious …!


I hope the infection will settle down as it is and that the infection will not spread again …!






Please be careful when you go out!
