Why Anemia Increases Risk for Severe COVID-19⁴
Another report, which also concluded that having anemia might mean developing a severe infection, tried to explain the possible reasons.
Firstly, the researchers pointed out that low levels of red blood cells mean the oxygen delivery system is not optimal. When organs don’t receive enough oxygen, they malfunction. And of course, multiple organ dysfunction—particularly lung dysfunction, also affects severity of COVID-19.
The researchers also explained that COVID-19 can worsen the state of the patient’s anemia because the virus interacts with hemoglobin molecules, the protein in the red blood cells.
Anemia and COVID-19: The Death Rates⁵
One report mentioned that anemia was independently associated with increased odds of all-cause mortality in hospitalized patients with COVID-19.
In their study, they noticed that anemia increases the risk of death in hospitalized COVID-19 patients from any cause.
