Kaimann D, et al. - Various measures have been implemented by the countries to interrupt the transmission of the COVID-19 from person to person and prevent an overload of their health systems. In this study, the impact of these measures was assessed by using a sample of 68 countries, Puerto Rico and the 50 federal states of the United States of America, four federal states of Australia, and eight federal states of Canada, involving 6,941 daily observations. After controlling for daily COVID-19 tests, evidence was gained indicating reduction in the growth rate of the coronavirus and thus the peak of daily confirmed cases in correlation with school closures, shut-downs of non-essential business, mass gathering bans, travel restrictions in and out of risk areas, national border closures and/or complete entry bans, and nationwide curfews. In addition, they gained evidence indicating that combinations of these measures lower the daily growth rate at a level outweighing that of individual measures. Consequently, and despite extensive vaccinations, it was contended that the implemented measures help containment of the spread of the COVID-19 pandemic and ease the overstressed capacity of the healthcare systems.
