According to Keio University, Professor Hamaoka has an impact on health such as "cumulative positive person lethality rate", "cumulative number of people tested for cumulative positive person", "number of beds secured per capita", and "accommodation room occupancy rate". Ten indicators were set from the viewpoints of measures, measures, cooperation of citizens, and impact on the economy, and 10 prefectures were evaluated.

　Tottori Prefecture, which received the highest evaluation, took the same measures as Taiwan and New Zealand, which are suppressing infection by strengthening the inspection system, and it was effective, "cumulative number of inspections for cumulative positives", "per population" It received outstandingly high evaluations in the two items of "Number of beds secured for acceptance".

　On the other hand, in Osaka Prefecture, which is the lowest in the ranking, the number of people tested is linked to the number of positive people, and the positive rate is also high.Professor Hamaoka pointed out that the inspections were generally insufficient, and that the failure of countermeasures had a serious impact on the economy, such as the long-term stagnation of guest room occupancy rates.

　Tokyo is also listed at the bottom of the ranking.Citizens' self-restraint and people's flow are relatively highly evaluated, and Professor Hamaoka thinks that despite the cooperation of the citizens, the city is not doing what it should do, which has a negative impact on health and the economy. ..
The research results were published in the May issue of the magazine "Science" of Iwanami Shoten.
