KEILAR: New research shows your blood type may be linked to your coronavirus risk. CNN health reporter, Jacqueline Howard, is following the story. Tell us what these studies are finding about blood type, Jacqueline.</s>JACQUELINE HOWARD, CNN HEALTH REPORTER: Yes, Brianna, this is some new and emerging research that's kind of adding to our understanding of the link between -- a possible link, I should say, between your blood type and COVID-19 risk. Here's what the studies found. In the first study, when it comes to success susceptibility, it was conducted out of Denmark, and that study found that among people who tested positive for COVID-19, 38 percent of them were blood type "O." And that percentage is lower than how many people in the general population, who haven't been tested, were blood type "O," which was 42 percent in the study. And when it comes to severe illness, another study found that among critically ill COVID-19 patients in Canada, 84 percent of those patients had blood types "A" or "AB". Excuse me, 84 percent of those with blood types "A" or "AB" needed mechanical ventilation, whereas 61 percent of those with types "O" or "B" did. Also in that study, Brianna, patients with blood types "A" or "AB" were in the ICU for about four days longer than those with blood types "O" or "B." So you see there's a connection there. But more research is needed to really take a deep look at what this connection could really mean for us. Back to you -- Brianna?</s>KEILAR: So interesting. Definitely looking forward to more research on that. Jacqueline, thank you. President Trump is set to host a rally in Iowa tonight, a state with one of the highest coronavirus positivity rates in the country right now.
