Hello! Today, we will talk about this topic that seems of great importance to share with you because some of the governments have suggested that the detection of antibodies to the COVID-19 could serve as the basis for an “immunity passport” or “risk-free certificate” that would enable individuals to travel or to return to work, assuming that they are protected against re-infection.
This is all depending on what type your blood is, you may have a lower risk of getting COVID-19, according to new preliminary research. Several early studies have shown that people with O blood type are less likely to be hospitalized and test positive for COVID-19 than people with A, B, or AB blood types.
In a new preprint report this month, researchers compiled data of nearly 2,000 patients hospitalized for COVID-19 in Italy and Spain. They found people with type A blood had increased risk for respiratory failure and while type O blood had a protective effect.
This doesn’t mean people with type O blood are completely protected, some people with type O blood still experienced respiratory failure. But for people who know they have type A blood, they should continue to take extra precautions to prevent COVID-19. Biotechnology company has preliminary data on more than 750,000 people that found that people with O blood type are between 9 to 18 per cent less likely to test positive for COVID-19 than others, making them the lowest blood group to report a positive test for COVID-19. It is still unknown how specifically blood type could increase or decrease a person's risk for having Covid-19, this is just a hypothesis.
