Cross-Country Age Disparities in COVID-19 Cases with Hospitalization, ICU Usage, and Morbidity

TL;DR

This study analyzes how age-related COVID-19 case severity and outcomes vary across countries by examining demographic data, providing estimates for cases, hospitalizations, ICU admissions, and fatalities.

Contribution

It introduces a method to compare age-distributed COVID-19 data across countries and estimates key health metrics using diverse international data sources.

Findings

Age disparities in COVID-19 severity vary significantly across countries.

Conditional probabilities help attribute data variability to demographic differences.

Provides comprehensive country-specific estimates for COVID-19 health outcomes.

Abstract

In this paper, we examine cross-country differences, in terms of the age distribution of symptomatic cases, hospitalizations, intensive care unit (ICU) cases, and fatalities due to the novel COVID-19. By calculating conditional probabilities, we bridge country-level incidence data gathered from different countries and attribute the variability in data to country demographics. We then provide case, hospitalization, ICU, and fatality estimates for a comprehensive list of countries using the existing data from a variety of countries.
