OBJECTIVE
To describe lockdown-type containment measures and COVID-19 incidence in South Africa, Germany, Brazil, Spain, United States, Italy and New Zealand.
METHODS
This is a descriptive ecological study with data on daily incidence of confirmed COVID-19 cases from February 22 to August 31 2020, as well as information on lockdown measures implemented by the governments of each country.
RESULTS
Daily COVID-19 incidence (cases per 1 million inhabitants) decreased within three weeks after lockdown started in the countries that implemented it: South Africa (3.7 to 1.7), Germany (37.5 to 33.7) Spain (176.3 to 82.0), Italy (92.0 to 52.1) and New Zealand (7.5 to 1.7). As for Brazil and the United States, which did not implement lockdown, there was no considerable decrease.
CONCLUSION
After lockdown implementation, there was a considerable decrease in the number of confirmed cases.
目的
描述南非、德国、巴西、西班牙、美国、意大利和新西兰的封锁式遏制措施和 COVID-19 发病率。
方法
这是一项描述性的生态学研究，数据来自 2020 年 2 月 22 日至 8 月 31 日期间每日确诊 COVID-19 病例，以及各国政府实施的封锁措施信息。
结果
实施封锁后，在实施封锁的国家中，COVID-19 发病率（每百万人中的病例数）在三周内下降：南非（3.7 降至 1.7）、德国（37.5 降至 33.7）、西班牙（176.3 降至 82.0）、意大利（92.0 降至 52.1）和新西兰（7.5 降至 1.7）。而巴西和美国没有实施封锁，因此没有明显下降。
结论
实施封锁后，确诊病例数量显著下降。
