COVID-19 lockdowns
COVID-19 lockdowns
During the early stages of the COVID-19 pandemic, a number of non-pharmaceutical interventions), particularly lockdowns (encompassing stay-at-home orders, curfews, quarantines, cordons sanitaires) and similar societal restrictions), were implemented in numerous countries and territories around the world. By April 2020, about half of the world's population was under some form of lockdown, with more than 3.9 billion people in more than 90 countries or territories having been asked or ordered to stay at home by their governments.
COVID-19 lockdowns
In addition to the health effects of lockdown restrictions, researchers had found the lockdowns may have reduced crime and violence by armed non-state actors, such as the Islamic State, and other terrorist groups. In addition, lockdowns had increased the uptake of telecommuting, reduced airborne pollution, and increased adoption of digital payment systems.
Efficacy
Several researchers, from modeling and demonstrated examples, have concluded that lockdowns were somewhat effective at reducing the spread of, and deaths caused by, COVID-19. Lockdowns are thought to be most effective at containing or preventing COVID-19 community transmission, healthcare costs and deaths when implemented earlier, with greater stringency, and when not lifted too early.
