Is that a new trend with Omicron? In 2020 studies did not find a correlation with severity but did notice a correlation with detection.

Blood type is not associated with a severe worsening of symptoms in people who have tested positive for COVID-19, according to HMS researchers at Massachusetts General Hospital. Although the findings dispel previous reports suggesting that a certain ABO blood type could lead to increased disease severity, they did indicate that symptomatic individuals with blood types B and AB who are Rh+ are more likely to test positive for COVID-19 than people with other blood types. Symptomatic people with blood type O are less likely to test positive.

The bold part is basically what I am talking about. Even showing symptoms, still not testing positive. Severity is one thing but also long covid needs to be researched too in that regard.
