During a six-week period from July 20 to August 31, 2022, Japan experienced its highest level of COVID-19 infection ever, with an average of nearly 200,000 new infections per day nationwide. Cases requiring inpatient care peaked at 1,993,062. Twenty-seven prefectures (out of 47 prefectures) had an average hospital bed occupancy of 50% or higher, and bed occupancy in Kanagawa in particular reached 98% in mid-August. In Tokyo, bed occupancy by patients with severe COVID-19 reached 57% and peaked at 64% in mid-August. Although the number of new infections per day has decreased since September, hospital bed occupancy, the number of severe cases, and deaths remain high nationwide. Efforts including vaccination campaigns, domestic surveillance, and routine infection control measures based on the varied knowledge that the Japanese public already has should be thoroughly implemented to reduce the number of the infected in order to avoid an increase the number of serious cases and deaths.
2022 年 7 月 20 日至 8 月 31 日的六周期间，日本经历了有史以来最高水平的 COVID-19 感染，全国平均每天新增近 20 万例感染。需要住院治疗的病例达到峰值，为 1,993,062 例。27 个县（47 个县中）的平均住院床位占用率达到或高于 50%，特别是神奈川县的床位占用率在 8 月中旬达到了 98%。在东京，COVID-19 重症患者的床位占用率在 8 月中旬达到了 57%，峰值达到了 64%。尽管自 9 月以来，每天的新增感染人数有所减少，但全国的住院床位占用率、重症病例数和死亡人数仍然很高。应该彻底实施包括疫苗接种运动、国内监测以及基于日本公众已经掌握的各种知识的常规感染控制措施，以减少感染人数，避免重症病例和死亡人数的增加。
