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 that have declared a state of emergency as of the 15th, 4 prefectures to which the "priority measures for the prevention of spread" are applied, and the "priority measures for the prevention of spread" until the 11th of this month.

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.
