MONDAY, April 5, 2021 (HealthDay Information) — A or B, AB or O, it does not matter — your blood kind has nothing to do along with your threat of contracting extreme COVID-19, a brand new research concludes.
Early within the pandemic, some studies recommended folks with A-type blood have been extra inclined to COVID, whereas these with O-type blood have been much less so.
However a evaluation of almost 108,000 sufferers in a three-state well being community has discovered no hyperlink in any respect between blood kind and COVID threat.
“For the reason that starting of this pandemic, there have been associations postulated between blood kind and illness susceptibility,” mentioned Dr. Amesh Adalja, a senior scholar with the Johns Hopkins Heart for Well being Safety.
“From this huge research, it seems that there isn’t a affiliation between blood kind and susceptibility or severity, and different explanations have been seemingly current,” added Adalja, who had no function within the research.
An early report from China recommended that blood kind would possibly affect COVID threat. Subsequent research from Italy and Spain backed that up, researchers mentioned in background notes.
Nevertheless, different research out of Denmark and the USA provided blended and conflicting outcomes.
To clear issues up, researchers led by Dr. Jeffrey Anderson, from Intermountain Medical Heart Coronary heart Institute in Murray, Utah, analyzed information from tens of 1000’s of sufferers with Intermountain Healthcare, a nonprofit well being system of 24 hospitals and 215 clinics in Utah, Idaho and Nevada.
Of these within the evaluation, almost 11,500 examined optimistic for coronavirus, whereas the remaining examined adverse.
Blood kind didn’t play a big function in anybody’s threat of contracting COVID, the researchers reported April 5 in JAMA Community Open.
“I’ve at all times mentioned this complete factor with the blood sorts is way hoopla about nothing,” mentioned Dr. Aaron Glatt, chairman of the division of drugs and hospital epidemiologist at Mount Sinai South Nassau in Oceanside, N.Y. “It was by no means a big sufficient factor that individuals ought to be terrified if they’ve one type of blood kind or reassured if they’ve one other blood kind. It by no means made any sensible distinction.”
