Lockdown, essential sectors, and Covid-19: Lessons from Italy

Area of Science:

• Epidemiology
• Public Health
• Health Economics

Background:

• The first wave of the COVID-19 pandemic necessitated widespread lockdowns.
• Essential sectors were often exempted from stringent lockdown measures.
• The impact of economic activity on disease transmission and mortality requires detailed investigation.

Purpose of the Study:

• To investigate the relationship between economic activity and COVID-19 infections and all-cause mortality.
• To quantify the impact of essential sector operations during lockdown exemptions.
• To assess the role of local healthcare systems in mitigating COVID-19 mortality.

Main Methods:

• Difference-in-differences framework utilizing provincial data.
• Analysis of essential sector worker distribution and administrative data.
• Examination of healthcare system capacity (general practitioners, hospital beds).

Main Results:

• A standard deviation increase in essential workers per square kilometer correlated with 1.1 additional daily cases and 0.32 additional daily deaths per 100,000 inhabitants.
• Approximately one-third of COVID-19 cases and 13% of deaths (March-May 2020) were linked to less stringent lockdowns for essential sectors.
• Sector-specific effects on transmission and mortality were observed.
• Higher numbers of general practitioners and hospital beds per capita were associated with reduced mortality.

Conclusions:

• Exemptions for essential sectors during the initial COVID-19 lockdown significantly contributed to disease spread and mortality in Italy.
• Local healthcare system capacity is a crucial factor in reducing COVID-19 related fatalities.
• Policy interventions regarding essential sector operations and healthcare resource allocation are vital during pandemics.
