[just a cold?] What will happen after COVID-19 is changed to Category 5?




On May 8th, COVID-19 will be changed to Category 5, so the daily number of new infections will no longer be announced…!


*The Japanese government has decided to leave it up to individuals to decide whether or not to wear a mask after March 13th.

*On May 8, the Japanese government will change the handling of COVID-19 under the Infectious Diseases Law from “category 2 = dangerous disease” to “category 5 = common cold”.


Various local governments and great people are disseminating information about what will happen after the change to 5 types.
For example, Osaka looks like this ↓


Governor Yoshimura of Osaka Prefecture

“COVID-19 is not the same as the flu”

“The power to spread infection is still much stronger than influenza”

“Since it is not seasonal, it is difficult to know when the infection will occur”

“As a government, we will focus on protecting high-risk people after changing to Class 5”


In addition, since each municipality has different information dissemination methods and countermeasures after the 5th class change, each municipality has announced it on its web page.


Ex) Tottori Prefecture


Since the information is getting a little jumbled like this, and the world after changing the 5th class will start tomorrow, so I would like to briefly summarize “What will change when changing to the 5th class” again!




 About the number of new infected people 

As you all know, there will be no more daily announcements of new infections.
After that, it seems that it will be announced once a week, every Friday, but compared to the past, it will be a less informative method.


Why is that…

↑ In this way, instead of counting all infection reports nationwide, after that, the number of infected people will be aggregated from only 5,000 medical institutions out of about 120,000 medical institutions nationwide.


*For the first time, on May 19th, the number of infected people from May 8th to May 14th will be announced.


That’s right, we won’t know the infection status after the end of Golden Week until two weeks later, and we can only know the reports from a small number of medical institutions.


 About the number of severe cases, deaths, and hospitalizations 

The release of the death toll will end completely on May 9th.
After that, along with the Ministry of Health, Labor and Welfare’s “Vital Statistics,”
the total number of deaths will be finalized in two months, and
the detailed cause of death will be available
in five months.
Therefore, we may not know how many people died from the infection during Golden Week until around October.


In addition, only the number of severely ill patients and the number of hospitalized patients will be collected from all medical institutions and will continue to be published once a week!
(*In case of emergency, it would be a problem if the medical system was tight, so they will continue to do so to understand the situation.)


 About the number of medical institutions that can be examined 

Currently (before the change to Category 5):
Approximately 42,000 medical institutions nationwideCurrently

After that (after changing 5 types):
Approximately 64,000 medical institutions nationwide
↑Yeah, not much different from before (dry laugh)
The disease that chooses a medical institution seems to be a “common cold”…


In principle, medical expenses are to be borne by the patient, but…
When hospitalized: High medical expense subsidy system is applied + 20,000 yen reduction
Outpatient: High medical expense subsidy system is applied to expensive medicines


In addition, about 8,200 hospitals, which are all hospitals in Japan, will accept inpatients.


In addition, it seems that COVID-19 patients will be hospitalized not by ward (building), but by preparing a dedicated hospital room for each ward.


 Method for confirming the presence of new variant 

They plan to continue genome analysis, which is the genetic analysis of viruses, while reducing the scale to about a quarter of what it used to be.
(*In the future, 100 cases per week will be analyzed by prefectures, and 200 cases per week will be analyzed by the National Institute of Infectious Diseases.)


 About refraining from going out after infection 

・It is recommended to refrain from going out for 5 days from the day after the onset of symptoms.

For 10 days after the onset of symptoms, the virus may be shed, so it is recommended to wear a mask and avoid contact with people who are at high risk of becoming seriously ill.

There is no need to refrain from going out in the future for people who have been in close contact.
 They just say that “please pay attention to your physical condition.”




Roughly summarized, it looks like this!
In the future, the situation will be like “infectious diseases like influenza will continue to be prevalent all year round”, but please be careful not to get infected when you go out…!
(*In fact, it’s “more contagious than the flu”, but… dry laugh)





This is how the city looks like today! ↓

I hope the infection doesn’t spread…!

(*Unit: person (number of infected people on that day))



*The Japanese government has decided to change the handling of COVID-19 under the Infectious Diseases Act from “category 2 = dangerous disease” to “category 5 = common cold” on May 08, 2023. Along with this, the number of new infections will only be counted from about 5,000 medical institutions, so it is highly likely that the daily number of new infections will no longer be announced on May 8.
