Contrary to the results of past studies, a new study has shown that people’s blood type does not play a role in the risk of COVID19 or severe infection. The findings of the new study have contradicted many global studies that have shown that blood type might be a factor responsible for why some people suffer more severe symptoms of coronavirus than others. The new study has been done by experts from Intermountain Healthcare. The lead author of the new study, Dr. Jeffrey Anderson, who is also a cardiologist at the Intermountain Medical Center Heart Institute, has said that identifying people who are at a greater risk of the disease and building risk scores have been their main goals.
He has said that health experts use all sorts of risks to identify whether someone should be hospitalized or not and what treatment they should be given. Dr. Anderson has said that the results of his study clearly show that ABO blood type is not a factor that is required to evaluate COVID19 risk. He has said that finding actual risk factors can help experts come up with better treatment for patients. The new study supports the fact that the risk of COVID19 is higher among elderly people and those who are dealing with obesity, diabetes, high blood pressure, and lung or heart diseases.
Last year, a study that has been done in China has shown that blood type has a role to play in the risk of being infected with the virus. This study has shown that people with blood type A are at higher risk of COVID19 and people with blood type O are at a lower risk of being diagnosed with COVID19. However, experts from Spain and Italy have claimed that blood type is not a factor for contracting the virus rather it plays a role in the severity of the disease. It is uncertain how many health experts have made changes in their COVID19 treatment as per these findings. Experts who have been involved in the new study have looked at many studies that have come out with varying outcomes.
One study from Denmark has found that blood type is responsible for infectivity but it does not affect the severity of infection. Research that has been done by experts from New York and Boston has found that there is no link between blood type and infectivity or severity of COVID19. Scientists from Intermountain Healthcare, Stanford University, and the University of Utah School of Medicine have looked at the data of 107796 people who have tested positive for COVID19 in Utah, Idaho, and Nevada from March 3, 2020, to November 2, 2020. The database has provided details about COVID19 test results of patients and their blood type. It has given the details of how severe the infection has been among patients who have been admitted to the hospital.
The study has noted that nearly 10.6 percent of around 108000 people who have been enrolled in the new study have been infected with the SARS-CoV-2 virus. Experts have said that percentage of people who have tested positive has echoed the percentage of people who have tested negative for COVID19. Around 39.6 percent of people with blood type A have been tested positive. At the same time, nearly 40.6 percent of people with blood type A have tested negative as well. Around 9 percent of people with blood type B have turned positive for COVID19 and 9.3 percent have turned out to be negative. People with blood type AB have contributed to 3.2 percent positive results and 3.3 percent negative tests. While 48.1 percent of people with blood type O have been diagnosed with the virus and 47.1 percent of them have tested negative. Around 2326 patients out of 11468 positive patients have been hospitalized and 706 of them have been admitted to the intensive care unit.
People with blood type A have contributed to 38.6 percent of hospitalization and 39.9 percent of non-hospitalized cases. Around 36.4 percent of people with blood type A have been in ICU. This blood type has accounted for 39.5 percent of non-ICU cases. Blood type B has contributed to 8.8 percent of hospital admissions and 9.1 percent of non-hospitalization cases. This blood type has been responsible for 8.6 percent of ICU admissions and 8.9 percent of non-ICU cases. People with blood type AB have accounted for 3.4 percent of hospitalizations and 3.1 percent of non-hospitalization cases. They have added to 2.8 percent of ICU cases and 3.6 percent of non-ICU cases. Nearly 49.2 percent of hospitalizations have included people with blood type O. This blood type has accounted for 47.9 percent of non-hospitalization cases.
