Do mosquitoes transmit Coronavirus? Here’s what study says

"While it is still very early in the study, 23andMe's preliminary investigation into genetics seems to support these findings", the company says on its website, referring to previous studies linking blood type with susceptibility to the novel coronavirus.

The novel coronavirus has infected more than 13.8 million people around the world and killed almost 600,000 since it emerged in China late a year ago.

Meanwhile, blood group A individuals appear to have a higher risk of infection, the ABO Blood Groups and Covid-19 report concludes.

Dr. Tatonetti, along with Michael Zeitz, a graduate student, looked over the medical records of 7,770 people tested positive of COVID-19 in the past few months during the pandemic and found that people who were Type A have a somehow lower risk of being placed on ventilators. Australia has reported more than 11,000 cases and 116 deaths.

While the current swab/PCR tests are used to identify people who are now positive with COVID-19, the agglutination assay can determine whether someone had been recently infected once the infection is resolved and could potentially be used to detect antibodies raised in response to vaccination to aid clinical trials, the researchers said.

Researchers at the university developed the simple agglutination assay, an analysis to determine the presence and amount of a substance in blood to detect the presence of antibodies raised in response to the SARS-CoV-2 infection.

They do not identify any policy implications.

Group O blood has been shown to be protective in other diseases, including malaria, where it lowers the risk of severe forms of the disease.

The initial results of Dr. Tatonetti and Zietz's study from 1,559 COVID-19 patients were published on preprint service medRXiv in April 2020, with their larger survey being reviewed for publication in a scientific journal.

Nevertheless, Zietz did find some interesting possibilities relating to COVID-19 and a person's blood type, saying that there is some sort of evidence that "certain blood types have different risks of clotting". Poon has also been active during the SARS-CoV-2 outbreak.
