Recent COVID-19 study suggesting that patients with this particular blood type may be more immune to COVID-19, Having type O blood can actually considerably reduce your risk of contracting coronavirus; according to recently published research of 23andMe
Some of characteristics that make COVID-19 more dangerous for us—high blood pressure, diabetes, obesity, low immunity, and heart disease, to name a few—there are some traits that might actually make you less at risk.
And according to recently published research, having type O blood can actually considerably reduce your risk of contracting coronavirus.
In a study released by genetic testing company 23andMe, researchers examined 750,000 participants and found a direct link between a patient’s blood type and their overall susceptibility to COVID-19. Overall, individuals with type O blood were 9 percent to 18 percent less likely to test positive when compared to other groups, while individuals with type O blood exposed to the virus were 13 percent to 26 percent less likely to test positive. This was in contrast to all other blood types, which the study found had very little difference in susceptibility.
They issued a statement saying, “Preliminary data from 23andMe’s on-going genetic study of COVID-19 appears to lend more evidence for the importance of a person’s blood type… in differences in the susceptibility to the virus.”
The researchers added how the study had been adjusted according to the person’s age, sex, ethnicity, body mass index, and co-morbidities. They said there are tiny differences in susceptibility among those with other blood types.
Lead researcher of the study, Adam Auton, compounded, “There have also been some reports of links between COVID-19, blood clotting, and cardiovascular disease. These reports provided some hints about which genes might be relevant.”
He further explained, “It’s early days; even with these sample sizes, it might not be enough to find genetic associations. We’re not the only group looking at this, and ultimately the scientific community may need to pool their resources to really address questions surrounding the links between genetics and COVID-19.”
The study has been on-going since April, not long after the worldwide pandemic started. The genetic testing company 23andMe started getting testing service providers to assist scientists so they can better comprehend how genetics may play a role as to why patients who acquire COVID-19 develop more severe infections than others.
The other group only contracts very mild symptoms or not showing any symptoms at all.
One of these is a study in China published in March, showing that those with blood type O may have more defense against the SARS-CoV-2, while those with blood type A are more at risk.
According to a study at Department of Biomedical Informatics at Columbia University Irving Medical Center, your blood type may indicate your risk of contracting the disease. Apparently, people with blood type A have a greater risk and people with blood type O are at a significantly less risk.
