| Summary: | New coronavirus SARS-CoV-2 had been stressed healthcare and examining resource since their quick
worldwide propagation and precedence of more at-danger people, which is a crucial quarrel. It has
been estimated that blood group could impact the danger of serious Covid-19 according to the novel
proofs that have been proposed. Due to this, we performed a review by going through a number of articles
published regarding this subject, and we found out that blood group has a different impact on Covid19
infection accordingly, We find slightly increased infection prevalence among non-O types. And the risk of
intubation was decreased among A and increased among AB and B types, compared with type O. also
we estimate Rh-negative blood type to have a protective effect to the high COVID19 infection
epidemiology, severe infection, and the need for intubation. while the risk of death was increased for type
AB and decreased for types A and B. Studies add to the growing body of evidence suggesting blood
type may play a role in COVID-19.
All these data are supported with evidence suggesting that blood group might take part in COVID-19
infection but further studies are needed to investigate more.
