Anemia
The primary function of hemoglobin is to secure atmospheric oxygen from the lungs to the blood and deliver the oxygen to the tissues of the body. There are over 400 types of anemia (Yikes!). But the most common is caused by iron deficiency. Common causes of deficiency include not getting iron rich foods in your diet or the taking of antacids (Tums, Rolaids, etc.) plus a crazy long list of prescription medications (seriously talk to your pharmacist to check the drugs you may be taking). In older patients, anemia of any degree contributes significantly to morbidity (getting a disease) and mortality (dying) and has a significant effect on the quality of life.

Article titled: Serum Iron Levels as a Potential predictor of CoronaVirus Disease 2019 severity and mortality: a retrospective study. Published from WuHan China Medical Center
90% of sick patients had low serum iron levels. And Serum iron levels could predict the severity of the case.
Meaning: Almost all hospitalized COVID cases in WuHan, China were iron deficient and the seriousness of the infection could be predicted by how low the iron levels actually were!

Iron metabolism and Anemia play an important role in multiple organ dysfunction syndrome in COVID-19. Hemoglobin levels were lower in older age, diabetes, hypertension and those with overall comorbidities (illnesses).
Journal of Clinical Medicine July 2020
Anemia was associated with a significantly higher in-hospital mortality rate and linked to advanced inflammation and significantly longer hospital stay. Initial (or pre-existing) anemia is associated with increased mortality. Anemia is associated with Severe COVID19 disease and an unfavorable outcome.
When a person is anemic, they will be starved for oxygen which is exacerbated (made worse) with an illness such as COVID-19.

Lacto-Fermented foods increase the availability of iron (ferric iron). Eating sauerkraut helps you absorb iron in your diet.
Iron Deficiency, Anemia, affects 33% of the world's population and is associated with chronic kidney disease, chronic heart failure, cancer and inflammatory bowel disease.
Symptoms include: hearing loss and tinnitus, fatigue, weakness, fast heartbeat, brittle nails, pale skin and shortness of breath.
