ONS survey: England seeing 27,900 new Covid-19 cases per day

The research indicated that individuals with blood types A, B, and AB were also at higher risk of exhibiting thrombosis - the clotting of blood inside a blood vessel - and cardiovascular diseases, which are significant co-occurring conditions among hospitalized Covid-19 patients.

They said that it can not be assumed that people who are at lower risk of severe illness and death from COVID-19 are also at low risk of ongoing COVID.

Based on the changes in the ratio of these two molecules over time, the researchers developed a point system where each 1-point increase was associated with 5.6 times increased odds for a more severe outcome.

The findings are reported in a pair of studies published October 14 in the journal Blood Advances.

Among the COVID-19 patients, there was a lower percentage of people with blood type O and higher percentages of those with with types A, B and AB. No associations were found between non-O blood groups and comorbidities that might explain infection rate differences. Among the COVID-19 positive, they found fewer people with blood type O and more people with A, B, and AB types. Further investigations on the mechanism of the different susceptibility to COVID-19 between blood group A and O individuals are needed and regardless of your blood type, you need to follow public health recommendations.

A study in June looking at patients in Italy and Spain found that blood type O had a 50 percent reduced risk of severe coronavirus infection (i.e. needing intubation or supplemental oxygen) compared to patients with other blood types.


Distribution of blood groups was compared with data from non-tested individuals.

Blood donation organisation Australian Red Cross says that 40 per cent of the Australian population has O blood type making it the most common group. Also, they are less prone to get severely sick even if they get infected. "And if you're blood group O, you're not free to go to the pubs and bars".

Together, these findings suggest that patients in these two blood groups may have an increased risk of organ dysfunction or failure due to COVID-19 than people with blood types O or B. Furthermore, while people with blood types A and AB did not have longer overall hospital stays than those with types O or B, they did remain in the intensive care unit (ICU) for a longer average time, which may also signal a greater COVID-19 severity level.

Research is correlating the idea that people with blood group O are on a little advantage during this pandemic.

There are four main blood groups - defined by their numbers of antigen and antibody proteins.
