Government-ordered physical distancing mandates have reduced the spread of COVID-19, preventing nearly 600,000 cases within three weeks, reports a new study.
Government's physical distancing orders during March significantly slowed the COVID-19 epidemic, leading to a reduction of over 600,000 cases within three weeks of implementation, reveals a new study. The findings of the study are published in the journal PLOS Medicine. According to the study between March 10 and March 25, all 50 states and the District of Columbia enacted at least one statewide physical distancing measure to help stop the spread of Covid-19.
‘Statewide social distancing measures slowed COVID-19 growth and also bought our health care leaders some time to fortify their surge capacity to deal with the epidemic.’
"Many have strongly suspected that physical distancing policies helped interrupt Covid-19 transmission during the early days of the US epidemic," said study author Mark J Siedner from the Massachusetts General Hospital (MGH). "This study adds clear evidence to support those suspicions. The results show the timing of government-issued orders correlated strongly with reductions in both cases and deaths," Siedner added.
For the results, the research team analyzed data from the first five months of the COVID-19 pandemic in the US. They collected data on government-issued orders on statewide physical distancing measures and compared changes in Covid-19 cases and COVID-19-attributed deaths in states that implemented physical distancing measures before and after implementation.
The results show the average daily Covid-19 case growth rate began declining approximately one incubation period (i.e., four days) after implementation of the first statewide physical distancing measures.
The period of time required for the number of cases to double (epidemic doubling time) increased from approximately four days to eight days within three weeks of implementation.

The study looked at a wide array of measures, including school and business closures, restrictions on public gathering, and shelter-in-place orders. Most combinations of these orders appeared to have similarly beneficial effects.

"The findings show that physical distancing measures slowed the growth of the Covid-19 epidemic and saved lives, and also bought our health care leaders some time to fortify their surge capacity to deal with the epidemic," the study authors noted.
