Age, COVID-19-like symptoms and SARS-CoV-2 seropositivity profiles after the first wave of the pandemic in France

Fabrice Carrat et al.

Summary: This study confirmed the independent effects of age and symptoms on the serologic profile of anti-SARS-CoV-2 antibodies, while also pointing out a non-linear relationship between age and antibody positivity rate.

The Role of ABO Blood Type in Patients with SARS-CoV-2 Infection: A Systematic Review

Federico Banchelli et al.

Summary: This study systematically investigated the association of ABO blood group with susceptibility to SARS-CoV-2 infection. The results showed that blood type O was slightly less associated with infection, while blood type A was slightly more associated with infection.

ABO blood group and link to COVID-19: A comprehensive review of the reported associations and their possible underlying mechanisms

Eric Pereira et al.

Summary: The ABO blood group is associated with susceptibility to COVID-19 infection, with type O blood being protective and type A blood being a risk factor. The severity and mortality of COVID-19 are most associated with type A blood, while type O blood is considered a protective factor. The mechanisms underlying these associations are hypothesized to involve the presence of ABO antibodies and ABH antigens, as well as the risk of thromboembolic events.

ABO Blood Types and COVID-19: Spurious, Anecdotal, or Truly Important Relationships? A Reasoned Review of Available Data

Jacques Le Pendu et al.

Summary: Studies suggest that blood type O may be associated with a lower risk of COVID-19, while non-O blood types may be detrimental. Two major hypotheses explain these findings, involving protective antibodies and thrombosis risk. The ABO coefficient of variation may determine the impact of the ABO system on virus transmission.

Antibody status and cumulative incidence of SARS-CoV-2 infection among adults in three regions of France following the first lockdown and associated risk factors: a multicohort study

Fabrice Carrat et al.

Summary: During May-June 2020, the seropositivity to anti-SARS-CoV-2 antibodies in the French adult population was around 10%, varying across different regions. Younger age, having children or adolescents in the household, and being a non-smoker were associated with higher seropositivity rates.

Relationship Between the ABO Blood Group and the Coronavirus Disease 2019 (COVID-19) Susceptibility

Jiao Zhao et al.

Summary: There is a relationship between ABO blood group and susceptibility to COVID-19, with people with blood group A having an increased risk of infection and those with blood group O having a decreased risk.

Comparative Performance of Five Commercially Available Serologic Assays To Detect Antibodies to SARS-CoV-2 and Identify Individuals with High Neutralizing Titers

Eshan U. Patel et al.

Summary: Accurate serological assays are crucial for detecting SARS-CoV-2 antibodies, but commercial EIAs may not always accurately detect high nAb titers in individuals, indicating the limitations of current diagnostic methods for COVID-19 convalescent plasma donation.
