The COVID-19 pandemic has led to a global health crisis with severe economic social and psychological consequences. Despite the fact that there were multiple crises in recent years, such as natural disasters, economic crises, and even epidemics, the coronavirus pandemic is the first in 100 years to severely affect the entire world. The economic effects of the COVID-19 pandemic concern an impending global recession caused by the lockdown of non-essential industries and the disruption of production and supply chains Social consequences may be visible in many areas, such as the rise in family violence the ineffectiveness of remote education, and increased food insecurity among impoverished families due to school closures.
The coronavirus disease (COVID-19), discovered in December 2019 in China, has reached the level of a pandemic and, till June 2021, it has affected more than 171 million people worldwide and caused more than 3.5 million deaths all over the world The COVID-19 pandemic as a major health crisis has caught the attention of many researchers, which has led to the creation of a broad quantitative picture of human behavior during the coronavirus outbreak. What has been established so far is, among others, the psychological symptoms that can occur as a result of lockdown and the most common coping strategies. However, what we still miss is an in-depth understanding of the changes in the ways of coping with challenges over different stages of the pandemic.
As the COVID-19 pandemic enters its third year and the omicron variant becomes dominant, we propose an alternative strategy for dealing with COVID-19, called hybrid lockdown, that is, the combination of lockdown (the centralized and organized lockdown of the high-risk population) and free mobility (normal mobility) of the low-risk population. Such an approach will enable a country or region, especially with a high population density, to achieve significant prevention and control the effects of the COVID-19 pandemic at the least cost.
Using the synthetic control method, we construct counterfactuals for what would have happened if Sweden had imposed a lockdown during the first wave of the COVID-19 epidemic. We consider eight different indicators, including a novel one that we construct by adjusting recorded daily COVID-19 deaths to account for weakly excess mortality. Correcting for data problems and re-optimizing the synthetic control for each indicator, we find that a lockdown would have had sizable effects within one week. The much longer delay estimated by two previous studies focusing on the number of positives cases is mainly driven by the extremely low testing frequency that prevailed in Sweden in the first months of the epidemic. This result appears relevant for choosing the timing of future lockdowns and highlights the importance of looking at several indicators to derive robust conclusions. We also find that our novel indicator is effective in correcting errors in the COVID-19 deaths series and that the quantitative effects of the lockdown are stronger than previously estimated.

The COVID-19 pandemic has had significant global health, economic, social, and psychological consequences. It is the first pandemic in 100 years to affect the entire world. The economic effects are seen in an impending global recession due to lockdowns and disruptions in production and supply chains. Social consequences include increased family violence, ineffective remote education, and food insecurity among impoverished families.

The COVID-19 pandemic, which has affected millions of people worldwide and caused millions of deaths, has led to significant research on human behavior during the outbreak. While psychological symptoms and coping strategies have been identified, there is still a need for a deeper understanding of how coping strategies change over different stages of the pandemic.

A proposed alternative strategy for dealing with COVID-19 is the hybrid lockdown approach, which combines lockdown measures for high-risk populations with free mobility for low-risk populations. This approach aims to achieve significant prevention and control of the effects of the pandemic at minimal cost, especially in densely populated areas.

Using the synthetic control method, a study found that implementing a lockdown in Sweden during the first wave of the COVID-19 epidemic would have had sizable effects within one week. Correcting for data problems and considering multiple indicators, the study highlights the importance of looking at several factors when determining the timing of future lockdowns.
