Insights
This study analyzed factors influencing coronavirus disease 2019 (COVID-19) cases and deaths across 141 countries. Population size, median age, and average temperature significantly impacted COVID-19 mortality rates.
Area of Science:
- Epidemiology
- Public Health
- Global Health
Background:
- The COVID-19 pandemic, originating in Wuhan, China, has had a profound global impact.
- Understanding factors influencing disease spread and mortality is crucial for public health.
- A year into the pandemic, a comprehensive analysis of contributing factors is needed.
Purpose of the Study:
- To identify key factors affecting the number of coronavirus disease 2019 (COVID-19) cases and deaths.
- To analyze these factors in 141 countries one year after the initial outbreak.
- To provide data for policy formulation regarding COVID-19 management.
Main Methods:
- Data from 141 countries affected by COVID-19 were analyzed.
- Countries were categorized based on population size.
- Ordinary least squares regression was employed to determine statistical relationships.
Main Results:
- Total COVID-19 cases and deaths showed a significant correlation with national population levels.
- Higher median age and average temperature were positively associated with increased COVID-19 deaths.
- Population density was positively linked to COVID-19 deaths specifically in less populated countries.
Conclusions:
- Population size, median age, average temperature, and population density are significant factors in COVID-19 outcomes.
- Findings offer a benchmark for public health authorities in developing effective policies.
- Further research can refine understanding of COVID-19's complex global dynamics.
Abstract:
This paper attempts to find the factors that affect the number of cases and deaths of coronavirus disease 2019 (COVID-19) patients a year after the first outbreak in Wuhan, China. There were 141 countries affected with COVID-19 involved in the study. Countries were grouped based on population. Using ordinary least squares regression, it was found that the total number of cases and deaths were significantly related with the levels of population of the different countries. On the overall, median age of the country, and average temperature are positively related with the number of deaths from the virus. On the other hand, population density is positively related with the deaths due to COVID for low populated countries. The result of this preliminary study can be used as a benchmark for authorities in the formulation of policies with regards to treating COVID-19 related issues.
