Deans' stroke musings: Your Blood Type Doesn't Affect Covid-19

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Your Blood Type Doesn't Affect Covid-19

Damn, I guess this was wrong.

Study links blood type(O) to lower risk of catching coronavirus

Your Blood Type Doesn't Affect Covid-19

August 22, 2020

We are at least eight months into the Covid-19 new pandemic and we are quickly learning about this virus and how it affects our bodies. A few weeks ago there were reports that a person's blood type might protect them from getting the infection. We now know this is not true. But first, a quick tutorial on human blood type.

Each of us inherits our blood type that is carried by an antigen on our red blood cells (RBC). The RBC is the largest quantity of blood cells in our body and is mainly designed to carry oxygen to our tissues. Each of us is either Type A, Type B, Type AB or Type O with a protein that is either positive or negative and is called Rh factor. We know that these types are critical in blood transfusions and receiving the wrong type of blood will cause a severe reaction. Every time a person is administered blood they get a "type and cross" that checks the blood type and makes sure the proper transfusion is given. People with Type O blood have no antigens so they can be given to all blood types and are called the universal donor.

It is nice speculation that a blood type might be Covid protecting but the peer-reviewed data does not show any difference.

Harvard Mass General just reported on an observational study of 1289 Covid positive patients. They ranked them for race, age and co-morbidities and wanted to know if blood type had any effect on the severity of the Covid illness. They looked at admit, ICU admit, intubation and death and found that there was no difference between any of these outcomes and a patient's blood type.

Because we know inflammation plays a role in severity of illness, they also looked at markers of inflammation and blood type and found no difference.

Scientists will continue to learn more about Covid and how it behaves and why certain people have worse outcomes. For now it's not blood type.
