Will Rollback of Public Health Measures Affect COVID-19 Spread? New Simulator Demonstrates How

New York, USA - July 1, 2020

Experts from Resolve to Save Lives and Earthrise Media developed a simulator to help guide national decisions on public health and social measures, including stay-at-home orders.

July 2, 2020—As countries around the world begin to lift COVID-19 public health and social measures (PHSMs) such as stay-at-home orders, many are experiencing a concerning rise in case counts and death. Leaving those measures in place, however, has serious social and economic consequences. A new online tool, Public Health and Social Measures Simulator, demonstrates how the timing of different combinations of PHSMs could affect disease spread.

Countries are forced to find the balance between responding swiftly to disease spread while minimizing the negative impact of interventions on individuals and communities,” said Amanda McClelland, Senior Vice President, Prevent Epidemics at Resolve to Save Lives, an initiative of Vital Strategies. “Our new simulator helps decision-makers assess the timing and the type of measures to turn on and off to reduce people’s risk from COVID-19.”

The simulator, now available on, allows users to select their region to find results tailored by location. All results demonstrate two critical points:

“As the pandemic accelerates in countries and cities across the world, decisions about how best to reduce transmission while also preventing social and economic disruption are more important than ever," said Christopher Lee, Senior Technical Advisor at Resolve to Save Lives. “Early action to implement public health and social measures in the COVID-19 pandemic helped curb the spread of COVID-19 in some regions, including Africa, but these measures cause substantial economic and societal strain. Policymakers need flexible tools, informed by the best available data, to allow them to make decisions that affect all of society, and the new simulator can be a useful tool for governments to rely upon.”

The simulator allows governments to anticipate the impact of implementing and releasing different measures, even in the absence of exact epidemiology data, which is often delayed. Users are able to assess the impact of common PHSMs, such as sheltering in place, closing schools, canceling mass gatherings and shielding the elderly, based on how long they are implemented. This tool also illustrates the policy options clearly. Notably, it shows that when testing, isolation, contact tracing and quarantine activities are effectively scaled up, societies can reopen safely.
