Suceptibility to contagion of covid-19 associated with the abo Blood group in adult patients

Abstract

When reviewing articles on ABO blood type-related susceptibility to Covid-19 infection in adult patients, there is evidence that blood type A is associated with an increased risk of Covid-19 infection, followed by Italy and Spain, although Boston, Massachusetts and New York confirmed the specific association between ABO blood type and the disease; generating controversy for which a comparative study of cases and controls is required. If necessary, conduct molecular research to elucidate the relationship between blood groups and disease, through the broadest multicenter perspectives. Regarding the studies that focused on the plasma concentrations of VWF, they affirm that they may depend on the type of blood group, age, sex, pregnancy, menstrual cycle, protein variation and biochemical and immunological factors, other studies demonstrated that ACE2 is expressed in the oral cavity, enriched in epithelial cells of the tongue. The knowledge of the genetic and molecular bases of SARS-CoV-2 allows to visualize the possibility of establishing treatments to control and reduce the pathogenic effects of the disease. Hypertension is the leading global cause of mortality, however, there is currently no literature to support that hypertension and hepatitis increase the risk of COVID-19 infection. New data were presented whose finding implied that pregnant women with blood group A would require additional surveillance by doctors with greater personal protection to reduce the risks of COVID-19 infection.
