Two new peer-reviewed studies in the journal Nature found that lockdowns, stay-at-home orders, closed schools, and canceled events prevented millions of Covid-19 cases and deaths.
One of the studies estimated the number of Covid-19 cases with and without these public health measures. In the US, the measures stopped 4.8 million more confirmed cases of Covid-19 and up to 60 million infections in total. In a second study, researchers looked at the number of deaths from Covid-19 in 11 countries in Europe. They found that 3.1 million deaths in these countries were prevented.
