The government's "Coronavirus Infection Control Subcommittee" has "the degree of medical tightness," "the number of medical treatments," and "positive PCR test" as indicators for determining which of the four stages that indicate the infection status. It shows five rates: "rate", "number of newly infected people", and "ratio of people whose infection route is unknown".

Of these, there are three items for "medical pressure": "bed usage rate," "hospitalization rate," and "bed usage rate for the severely ill."

According to the summary of the Cabinet Secretariat, Tokyo and Okinawa prefectures where emergency declarations have been issued as of 12th of this month, 4 prefectures to which "priority measures such as prevention of spread" are applied, and "prevention of spread, etc." until 11th of this month. In a total of 11 prefectures to which the "Priority Measures" were applied, there are several items that correspond to the most serious "Stage 4" in Tokyo and Okinawa.

Regarding the bed-related indicators, some local governments publish different values ​​based on the "number of beds that can be immediately responded" that can be accepted immediately.

Medical pressure bed usage rate

First is the tightness of medical care.

As a guide, the bed usage rate is 20% or more for stage 3 and 50% or more for stage 4.

▽ Aichi 9 people in the

prefecture ▽

8 people in Kyoto prefecture ▽

6 people in Hyogo prefecture ▽

8 people in

Fukuoka prefecture.

Test positive rate

This is the positive rate of PCR tests for the last week.

As a guide, stage 3 is 5% or more, and stage 4 is 10% or more.

▽ 6.8% in Tokyo

3.4% in Okinawa

4.1% in Saitama

5.6% in Chiba

▽ 49% in Hokkaido

46% in Aichi

▽ Kyoto 48%

▽ 65% in Hyogo prefecture ▽

47% in Fukuoka prefecture.

The newly adopted "hospitalization rate" as an index is the ratio of those who have been hospitalized to all the recuperators.

As the number of patients with the new coronavirus increases, the number of patients who should be hospitalized but cannot be hospitalized and receive medical treatment at home or institution increases. Therefore, the lower the "hospitalization rate", the more patients cannot be accepted. In other words, medical care may be tight.

However, the government's "New Coronavirus Infectious Disease Control Subcommittee" does not apply in the following cases.

▽ When the number of medical treatment is less than 10 per 100,000 population.

▽ When the number of new positives who need to be hospitalized can be hospitalized by the day after the notification of the outbreak.

No stage judgment is made for these municipalities.
