A new American study has just confirmed that people in group A are more at risk of contracting Covid-19 (or SARS-CoV-2) and developing complications. On the other hand, people in group O would present less risk.
Affinity for blood group A cells
Specifically, people with blood type A might be 20% more likely to become infected following exposure to SARS-CoV-2 compared to those with blood type O.
According to the authors of the research, “part of the Spike protein, which is essential for allowing the virus to invade cells, displays an affinity for blood group A cells, and the virus in turn also shows an ability to more easily infect blood group A cells. blood A”.
People with blood group O not fully protected
It is important to note that this preference does not mean that people with blood group O are completely protected and should neglect preventive measures. Furthermore, factors such as age and chronic diseases remain more important than blood type in determining the risk of serious infection with SARS-CoV-2.
This new study raises many questions and might help to better understand how the virus spreads and how to fight it. Further studies will be needed to dig deeper into this question and determine why the virus shows a preference for blood group A.
6,947,192 deaths worldwide
SARS-CoV‑2 belongs to the family of coronaviruses (CoV), a name linked to the “crown” that certain proteins form on the surface of these viruses. He was first identified in Wuhan, China, in December 2019.
Covid-19 has caused 6,947,192 deaths worldwide since the start of the pandemic.
