With the transition of the new corona to "Class 5", the Ministry of Health, Labour and Welfare announced for the first time the infection status nationwide by "fixed point grasp" from designated medical institutions.
The average number of patients per medical institution for the week ending May 5 was 14.1, an increase of 1.2 times from the previous week, and the Ministry of Health, Labour and Welfare said that "a moderate upward trend has continued since April."

With the shift of the new coronavirus under the Infectious Diseases Act to "Class 5," the Ministry of Health, Labour and Welfare has changed the method of grasping the epidemic situation from "total number grasp" that requires reports of all infected people to "fixed point grasp" based on weekly reports from about 5000,1 designated medical institutions nationwide.

Average number of patients per medical institution: 1.2, an increase of 63.1 times from the previous week

On May 19, the nationwide infection status was announced for the first time based on "fixed point grasp", and the total number of cases reported in the week up to May 5 was 14,1.

The average number of patients per single medical institution was 1.2922.

In order to analyze the trend of infections, the Ministry of Health, Labour and Welfare has also retabulated the number of infected people by week from October last year to May 1 by "fixed point grasp", and according to that, it increased by 2.63 times compared to the previous week.

This is the sixth consecutive week of increase from the previous week, and the Ministry of Health, Labour and Welfare says, "Although it is at a relatively low level, it has been on a moderate upward trend since April.

By prefecture, in descending order ▽
Okinawa Prefecture has 10.5 people ▽ Ishikawa Prefecture has 7.1 people ▽ Hokkaido has 46.6 people ▽ Niigata Prefecture has 4.6 people ▽ Yamanashi Prefecture has 07.4 people



, etc
. 90 prefectures increased from the previous week.

The Ministry of Health, Labour and Welfare (MHLW) has newly announced the "number of new hospitalizations" as one of the indicators for continuously grasping the epidemic situation in line with the shift to "fixed-point grasp".

In the week ending May 4, 36,4 people were newly hospitalized nationwide, almost unchanged with a decrease of 30 from the previous week, and the Ministry of Health, Labour and Welfare said that the epidemic situation is not such that the number of people who need to be hospitalized will increase sharply.

About past data and understanding future trends

"Fixed point grasp" is a method of continuously monitoring the status of designated medical institutions in order to grasp the trend and level of increase and decrease in the number of patients, and about 5000,1 medical institutions nationwide designated by prefectural governments report on the new coronavirus once a week.

The Ministry of Health, Labour and Welfare (MHLW) compared the total number of infected people nationwide based on the number of infected people in the "total number grasp" that has been conducted so far and the number of patients reported by medical institutions designated by "fixed point grasp" during the same period.

The target period was from October last year, when infections spread in the so-called "eighth wave," to May 8, the day before the transition to Class 10, and the range of variation in statistical differences is within 5%, which is a guideline.

As a result, the range of statistical variation is 5.7%, which the Ministry of Health, Labour and Welfare says is acceptable for both the whole country and prefectures.

In addition, the number of patients per week at approximately 10,2 medical institutions that conduct a "fixed point grasp" for the period covered in comparison is re-aggregated and published as a reference so that trends can be analyzed compared to the previous week.

On the other hand, for seasonal influenza, which is similarly "fixed-point grasping," we have established criteria for epidemic status such as "warnings" and "alerts," but for the new coronavirus, we cannot create standards for the time being because we do not have accumulated data.

For this reason, as one of the indicators to continuously grasp the epidemic situation, we have newly announced the number of new hospitalizations.

The Ministry of Health, Labour and Welfare (MHLW) will grasp the epidemic and medical crunch situation by observing the number of patients per medical institution and "new hospitalizations" based on "fixed point grasp", as well as the changes in the number of "hospitalized" and "seriously ill" that have been announced so far.
