A number of recent studies into COVID-19 have looked to see if blood type has any effect on your ability to resist or pick up the disease. One conclusion is that blood type does make a difference. In this post we check the findings of some major studies to see what this means for you and your health.
Researchers in China looked at the blood groups of 2,173 volunteers who had contracted Coronavirus. The study that was published concluded that those patients with blood group A were at higher risk of catching the disease than those from other blood groups. Other studies, notably from Spain and Italy, came to similar conclusions.
A Canadian study of 95 volunteers found that blood groups A and AB were more common amongst those patients, who would go on to suffer the severest symptoms of COVID-19. The study also suggested that these people were more vulnerable to breathing difficulties with the disease, requiring mechanical ventilation.
A larger, Danish study of a group of nearly 450,000 patients, found that those with blood group O were less likely to become infected with the virus. The same research also discovered that patients in any blood group who were Rh-negative had a much lower risk of developing severe symptoms, or even dying, from COVID-19.
I Have Blood Type A, Should I Be Worried?
All of these studies indicate very minor changes in susceptibility. Some had yet to be validated by peer review. So, no, you should not worry unduly. Your blood group may cause you to have a heightened chance of severe COVID-19 symptoms. However this does not mean it is going to happen. The multiple factors that need to be considered “more likely” is not the same as “definitely”
These kinds of studies have been carried out for years. Medical experts have always been intrigued by the link between blood type and the immune system. In these studies, experts want to know why some people have more chance of picking up or avoiding a virus such as COVID-19. This type of research can speed up the development of vaccines and other treatments and such studies help us to identify those groups of the population that may need extra support.
Understanding the Science Behind Blood Types and Covid-19
While these studies show a potential link between blood types and COVID-19 susceptibility, it’s important to understand the underlying science. Blood types are determined by the presence or absence of certain antigens on the surface of red blood cells. These antigens can affect how our immune system responds to various pathogens, including viruses like SARS-CoV-2.
One theory suggests that people with type A blood have more ACE2 receptors, which the virus uses to enter cells. This could explain why they might be more susceptible. On the other hand, type O blood contains anti-A antibodies, which may provide some protection against the virus.
However, it’s crucial to remember that blood type is just one factor among many that influence COVID-19 risk. Age, underlying health conditions, and lifestyle factors play significant roles too. Scientists are still working to fully understand these complex interactions.
As research continues, we may gain more insights into how blood types affect our immune responses. This knowledge could potentially lead to more targeted prevention strategies and treatments in the future.
How Can I Reduce My Risk of Catching Covid-19?
If you have not been vaccinated yet, there are still steps you can take to protect yourself. However vaccination is the best protection and you should go and get your jab as soon as you can.
For those people in blood group A, we advise that you continue to follow many of the well-known precautions. Stay at home as much as possible, wear a face covering and maintain social distancing. Eat well and maintain a strong immune system, take Vitamin D supplements and get a good amount of sleep.
Those with blood type O should also follow these sensible guidelines in order to avoid catching Coronavirus.
How to Find Out Your Blood Type Quickly at Home
Many of us don’t know their blood type, unless they have given blood or have a rare blood group. However, it is easy to check your blood type at home with a simple medical test.
Our easy to use, blood test kit below will indicate you if you are blood type A, B, O, AB or RhD positive or negative. The kit includes a lancet which pricks the finger to produce a small droplet of blood. This blood is then smeared on to the test card. and you be able to read the results and find out what blood type you are.
