MONDAY, April 5, 2021 (HealthDay Information) — A or B, AB or O, it does not matter — your blood sort has nothing to do along with your threat of contracting extreme COVID-19, a brand new research concludes.
Early within the pandemic, some reviews instructed folks with A-type blood had been extra vulnerable to COVID, whereas these with O-type blood had been much less so.
However a evaluation of practically 108,000 sufferers in a three-state well being community has discovered no hyperlink in any respect between blood sort and COVID threat.
“For the reason that starting of this pandemic, there have been associations postulated between blood sort and illness susceptibility,” stated Dr. Amesh Adalja, a senior scholar with the Johns Hopkins Heart for Well being Safety.
“From this massive research, it seems that there isn’t any affiliation between blood sort and susceptibility or severity, and different explanations had been possible current,” added Adalja, who had no position within the research.
An early report from China instructed that blood sort would possibly affect COVID threat. Subsequent research from Italy and Spain backed that up, researchers stated in background notes.
Nevertheless, different research out of Denmark and the US supplied 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, practically 11,500 examined constructive for coronavirus, whereas the remainder examined unfavorable.
Blood sort didn’t play a big position in anybody’s threat of contracting COVID, the researchers reported April 5 in JAMA Community Open.
“I’ve at all times stated this complete factor with the blood sorts is way hoopla about nothing,” stated Dr. Aaron Glatt, chairman of the division of medication and hospital epidemiologist at Mount Sinai South Nassau in Oceanside, N.Y. “It was by no means a big sufficient factor that folks must be terrified if they’ve one type of blood sort or reassured if they’ve one other blood sort. It by no means made any sensible distinction.”
