我们分析了2020年1月25日至5月6日东京和大阪爆发的2019年冠状病毒病(新冠肺炎)疫情的趋势。为了分析这些趋势并确定其中的重大变化，我们进行了连接点回归分析。从3月份的最后一周开始，东京和大阪的新冠肺炎病例数量激增。在4月的第二和第三周，东京(贝塔=157.53)和大阪(贝塔=60.96%)都经历了新冠肺炎病例的增长高峰。紧急状态宣布后近14天以来，大阪的病例数量显示出遏制的趋势，但在东京继续以令人担忧的速度增加(beta=90.66)。
We analyzed the trends of the coronavirus disease 2019 (COVID-19) outbreak in Tokyo and Osaka from January 25 to May 6, 2020. To analyze the trends and identify significant changes in them, we performed a joinpoint regression analysis. From the last week of March, the number of COVID-19 cases soared in Tokyo = 103.51) and Osaka (beta = 28.07). During the 2nd and 3rd weeks of April, both Tokyo (beta = 157.53) and Osaka (beta = 60.96) experienced peak growth in COVID-19 cases. Since almost 14 days after the state of emergency declaration, the number of cases showed a containment trend in Osaka, but continued to increase at a concerning rate in Tokyo (beta = 90.66).
