In their paper titled "Managing COVID-19 Pandemic without Destructing the Economy," authors David Gershon, Alexander Lipton, and Hagai Levine present an approach to effectively manage the COVID-19 pandemic without resorting to complete economic shutdowns. The authors utilize a comprehensive epidemiological model that considers various population groups and disease phases, including incubation, infection period, hospitalization, and intensive care unit (ICU) treatment. The analysis focuses on maintaining healthcare system capacity while avoiding lockdowns. The healthcare capacity is defined as the total number of hospital and ICU beds available in a country. To calibrate their model, the authors use data from recent research papers. By calculating the number of total and intensive care hospitalizations, as well as deaths over time for high- and low-risk population groups, the authors draw a significant conclusion. They find that countries can avoid lockdowns throughout the pandemic if they implement reasonable hygienic measures in a timely manner and have a sufficient number of spare ICU beds per million people (above approximately 100). For countries with a total number of ICU beds below this threshold, a limited quarantine period targeting specific high-risk groups is deemed sufficient. Additionally, when there is inadequate capacity within the healthcare system, the authors incorporate a feedback loop to demonstrate the quantitative impact of insufficient ICU units on the death curve. Interestingly, in scenarios where there is an inadequate number of ICU beds available, both full-quarantine and partial-quarantine outcomes are almost identical. This finding suggests that it may not be necessary to shut down the entire economy in such cases. Instead, only a limited-time quarantine for high-risk groups might be required while allowing the rest of the economy to remain operational. Overall, this study provides valuable insights into managing the COVID-19 pandemic by balancing public health measures with economic considerations. It highlights the importance of timely implementation of hygienic measures and ensuring adequate healthcare capacity - particularly in terms of ICU beds - to effectively navigate through this pandemic without resorting to complete economic shutdowns.
Authors propose a way to handle the COVID-19 pandemic without completely shutting down the economy. They use a model that looks at different groups of people and stages of the disease. The focus is on keeping enough hospital beds and ICU beds available while avoiding lockdowns. Healthcare capacity means the total number of beds in hospitals and ICUs in a country. Countries can avoid lockdowns if they have good hygiene measures and enough spare ICU beds for every million people (around 100 or more). If a country doesn't have enough ICU beds, a limited quarantine for high-risk groups might be enough. Having too few ICU beds has similar outcomes whether there's a full or partial quarantine, so a complete economic shutdown may not be necessary. It's important to act quickly with good hygiene practices and make sure there are enough healthcare resources, especially ICU beds, to manage the pandemic without shutting down the economy."

Managing the COVID-19 Pandemic without Destructing the Economy
The novel coronavirus (COVID-19) pandemic has had a devastating impact on global economies, with many countries resorting to complete economic shutdowns in an effort to contain the spread of the virus. In their paper titled "Managing COVID-19 Pandemic without Destructing the Economy," authors David Gershon, Alexander Lipton, and Hagai Levine present an approach to effectively manage the pandemic without such drastic measures. The authors utilize a comprehensive epidemiological model that considers various population groups and disease phases, including incubation, infection period, hospitalization, and intensive care unit (ICU) treatment.
Calibrating the Model
To calibrate their model, the authors use data from recent research papers. By calculating the number of total and intensive care hospitalizations as well as deaths over time for high- and low-risk population groups, they draw a significant conclusion: countries can avoid lockdowns throughout the pandemic if they implement reasonable hygienic measures in a timely manner and have a sufficient number of spare ICU beds per million people (above approximately 100).
Inadequate Healthcare Capacity
For countries with a total number of ICU beds below this threshold, limited quarantine periods targeting specific high-risk groups are deemed sufficient. Additionally, when there is inadequate capacity within healthcare systems - i.e., not enough ICU beds - feedback loops are incorporated into models to demonstrate how insufficient ICUs can affect death curves over time. Interestingly enough, in scenarios where there is an inadequate number of ICU beds available both full-quarantine and partial-quarantine outcomes are almost identical; suggesting it may not be necessary to shut down entire economies in such cases but rather only require limited quarantines for high risk populations while allowing other sectors to remain operational.
Conclusion
Overall this study provides valuable insights into managing COVID-19 by balancing public health measures with economic considerations; highlighting importance of timely implementation of hygienic measures as well as ensuring adequate healthcare capacity - particularly in terms of ICU beds - so that we can navigate through this pandemic without resorting to complete economic shutdowns
We analyze an approach to managing the COVID-19 pandemic without shutting down the economy while staying within the capacity of the healthcare system. We base our analysis on a detailed heterogeneous epidemiological model, which takes into account different population groups and phases of the disease, including incubation, infection period, hospitalization, and treatment in the intensive care unit (ICU). We model the healthcare capacity as the total number of hospital and ICU beds for the whole country. We calibrate the model parameters to data reported in several recent research papers. For high- and low-risk population groups, we calculate the number of total and intensive care hospitalizations, and deaths as functions of time. The main conclusion is that countries, which enforce reasonable hygienic measures on time can avoid lockdowns throughout the pandemic provided that the number of spare ICU beds per million is above the threshold of about 100. In countries where the total number of ICU beds is below this threshold, a limited period quarantine to specific high-risk groups of the population suffices. Furthermore, in the case of an inadequate capacity of the healthcare system, we incorporate a feedback loop and demonstrate that quantitative impact of the lack of ICU units on the death curve. In the case of inadequate ICU beds, full- and partial-quarantine scenarios outcomes are almost identical, making it unnecessary to shut down the whole economy. We conclude that only a limited-time quarantine of the high-risk group might be necessary, while the rest of the economy can remain operational.
