Insights
Blood type A is associated with higher COVID-19 spread and mortality. Understanding this link between severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) and ABO blood groups can aid pandemic control efforts.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Background:
- The COVID-19 pandemic, caused by SARS-CoV-2, presents a significant global health challenge.
- Understanding factors influencing SARS-CoV-2 transmission is crucial for effective pandemic response.
- The potential role of host genetics, such as blood type, in disease dynamics warrants investigation.
Purpose of the Study:
- To investigate the association between SARS-CoV-2 infection dynamics and ABO blood group distribution.
- To analyze how blood type prevalence correlates with COVID-19 epidemic indicators across different global regions.
Main Methods:
- Utilized big data from the WHO and Johns Hopkins University for early-phase COVID-19 epidemic data.
- Analyzed infection and death data from approximately 5.4 billion people across six WHO geographic zones.
- Calculated epidemic indicators including infection growth factor, case doubling times, and reproductive numbers in relation to blood type distribution.
Main Results:
- A significant positive correlation was found between the proportion of blood type A and infection/death growth factors.
- A significant negative correlation was observed between the proportion of blood type B and infection/death growth factors.
- Populations with higher proportions of blood type A (>=30%) exhibited greater infection and death cases, higher growth factors, and shorter doubling times, indicating more dynamic epidemic spread.
Conclusions:
- An association exists between SARS-CoV-2 infection dynamics and ABO blood group distribution.
- Blood type A prevalence may be linked to increased COVID-19 epidemic severity and spread.
- This finding could inform public health strategies for managing the COVID-19 pandemic.
Abstract:
The coronavirus disease 2019 (COVID-19) pandemic is currently the most critical challenge in public health. An understanding of the factors that affect severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection will help fight the COVID-19 pandemic. This study sought to investigate the association between SARS-CoV-2 infection and blood type distribution. The big data provided by the World Health Organization (WHO) and Johns Hopkins University were used to assess the dynamics of the COVID-19 epidemic. The infection data in the early phase of the pandemic from six countries in each of six geographic zones divided according to the WHO were used, representing approximately 5.4 billion people around the globe. We calculated the infection growth factor, doubling times of infection and death cases, reproductive number and infection and death cases in relation to the blood type distribution. The growth factor of infection and death cases significantly and positively correlated with the proportion of the population with blood type A and negatively correlated with the proportion of the population with blood type B. Compared with the lower blood type A population (<30%), the higher blood type A population (⩾30%) showed more infection and death cases, higher growth factors and shorter case doubling times for infections and deaths and thus higher epidemic dynamics. Thus, an association exists between SARS-CoV-2 and the ABO blood group distribution, which might be useful for fighting the COVID-19 pandemic.
