The spread of the virus might be dependent on the ABO compatibility between the spreader and recipient they encounter.

According to previous studies, blood type might play a significant role in driving the severity of the novel coronavirus (COVOD-19). Moreover, some studies have shown that individuals with blood type O are more protected against severe disease whereas individuals with blood type A may experience complications. Meanwhile, scientists/researchers around the world are racing to find an effective treatment or vaccine to cure the infection. The spread of the virus might be dependent on the ABO compatibility between the spreader and recipient they encounter.

Individuals with blood type O are at lower risk of getting COVID-19, according to several studies published worldwide during the global pandemic. Individuals with blood type A are significantly more susceptible to the virus and their mortality rate is high. The United States-based company, 23andMe examined more than 750,000 people to determine blood type O vulnerability. The results have shown that individuals with blood type O are at 14% (on average) lower risk than other blood types, after accounting for gender, age, co-morbidities, and ethnicity.

Their preliminary data suggests that people with blood type O appears to be more protective against the novel coronavirus. According to the research published in medRxiv, people with blood type A+ have a higher risk (around 45%) of respiratory failure whereas people with blood type O have a lower risk (around 35%) for respiratory failure. The dynamics of any infectious disease are important in determining the spread. To date, the virus has infected more than 14,457,900 folks and killed more than 605,205 people across the world. However, the total number of infections is not yet known as it is still actively growing. Moreover, all studies came to a similar conclusion, individuals with blood type O have less chance of getting COVID-19.
