March 2020 was a pivotal month for the worldwide geographic and numeric expansion of the first wave of Coronavirus Disease 2019 (COVID-19). We examined the major storylines that depicted this explosive spread of COVID-19 around the globe.
A detailed review of World Health Organization (WHO) situation reports, surveillance summaries, and online resources allowed us to quantify the increases in cases and deaths by region and by country throughout the month of March 2020.
During March, COVID-19 was officially declared by the WHO to be a pandemic. COVID-19 emerged from a focalized outbreak in the Western Pacific Region and rapidly proliferated across all continents worldwide. Globally, cumulative numbers of confirmed cases increased by a factor of nine throughout the month. During the entire month, cases rose exponentially throughout Europe. Starting in mid-March, confirmed cases accelerated coast-to-coast throughout the United States and, on March 26, the United States surpassed all other nations to rank first in numbers of cases. COVID-19 mortality lagged several weeks behind but by month's end, death tolls were also rising exponentially.
March 2020 was a consequential month when the COVID-19 pandemic wrapped completely around the planet, with outbreaks erupting in most nations worldwide.
2020 年 3 月是 2019 年冠状病毒病（COVID-19）第一波在全球范围内地理和数量扩张的关键月份。我们研究了描绘 COVID-19 在全球范围内迅速传播的主要故事情节。
详细审查世界卫生组织（WHO）的情况报告、监测摘要和在线资源，使我们能够量化整个 2020 年 3 月按地区和国家划分的病例和死亡人数的增加。
在 3 月，世界卫生组织正式宣布 COVID-19 为大流行。COVID-19 从西太平洋地区的一个集中爆发点出现，并迅速在全球各大洲传播。全球范围内，确诊病例数在整个月内增加了九倍。在整个 3 月，欧洲的病例呈指数级增长。从 3 月中旬开始，美国各地的确诊病例加速蔓延，3 月 26 日，美国超越所有其他国家，成为病例数最多的国家。COVID-19 的死亡率滞后了数周，但到月底，死亡人数也呈指数级增长。
2020 年 3 月是 COVID-19 大流行全面席卷全球的一个重要月份，世界上大多数国家都爆发了疫情。
