Your Blood Type May Predict Your Risk For Severe COVID-19

The results suggest that COVID-19 patients with A and AB blood types may have an increased risk of organ dysfunction or failure than those with type O or B blood, according to the researchers.

Though the study sample was small, the scientists believe congenital heart disease alone may not be enough to increase the risk of severe COVID-19 symptoms. But the impact of SARS-CoV-2 infection on individuals with congenital heart defects, who are generally younger than those with adult-onset heart disease, was unknown. There are 1,85,270 active patients in the state now.

The second study from Vancouver, Canada on 95 critically ill COVID-19 patients in a hospital found that-after adjusting for sex, age, and comorbidities-patients with blood types A or AB were more likely to require mechanical ventilation than patients with types O or B (84% vs 61%, P = 0.02), indicating higher rates of lung damage.

While it's still not clear whether this link is a direct cause-and-effect relationship or simply a coincidental correlation, the two new bits of research further builds on the idea that blood type might have some role in how Covid-19 affects people. Of the 9 patients who developed moderate to severe symptoms, 3 died.

Two new studies have weighed in with fresh evidence of the link between blood type and Covid-19, suggesting that people with blood type O appear to have a lower risk of falling severely ill with the infection while people with blood groups A or AB tend to exhibit greater disease severity.

More patients with type A and AB blood required dialysis for kidney failure, the study added. The researchers caution that individuals with congenital heart disease should continue to practice strict social distancing and follow all CDC guidelines as these measures are likely contributing to the study findings.

"It's possible that elderly patients with congenital heart disease might have a different risk profile than the general population", adds Brett Anderson, Florence Irving Assistant Professor of Pediatrics at Columbia University Vagelos College of Physicians and Surgeons and co-leader of the study.

Many studies have been published consistently with suitable hypotheses about how infectious the virus is, who is well on the way to be contaminated, how risky the virus can be for specific kinds of individuals, etc.
