Non-pharmaceutical interventions such as voluntary shelter-in-place, quarantines, and other steps taken to control the SARS-CoV-2 virus can reduce the peak number of infections, daily infection rates, cumulative infections, and overall deaths, a new study published in the journal PLOS ONE has found.

"High compliance with voluntary quarantine - where the entire household stays home if there is a person with symptoms or risk of exposure in the household - has a significant impact on reducing the spread," said Pinar Keskinocak, the William W. George Chair and professor in the H. Milton Stewart School of Industrial and Systems Engineering (ISyE) and director of the Center for Health and Humanitarian Systems at the Georgia Institute of Technology. "Shelter-in-place (SIP) puts the brakes on the spread for some time, but if people go back to 'business as usual' after SIP, the significant impact is lost, so it needs to be followed up by voluntary quarantine and other physical distancing measures."

Utilizing data from the state of Georgia, the study determined that a combination of non-pharmaceutical interventions, with various levels of compliance that change over time, could in some instances cut cumulative infections in half and reduce the peak number of infections to about a third of what could have been seen, "flattening the peak" to avoid overwhelming a state's healthcare system.
