COVID-19
Coronavirus disease 2019 or COVID-19 is a disease first associated with some people infected with the SARS-CoV-2 virus and later associated with some recipients of the COVID-19 vaccines.
COVID-19 Cases
A COVID-19 case has often been confused with a SARS-CoV-2 infection. However, viral infection has not historically implied disease. This has created substantial confusion, and made statistics harder to gather and evaluate.
Symptoms of COVID-19
COVID-19 is primarily associated with acute respiratory syndrome and vascular problems.

Long Haul COVID-19
A fraction of those who develop COVID-19 suffer long-term health consequences after recover from the acute form of the disease.

Asymptomatic COVID-19
We usually do not talk about an asymptomatic disease state in medicine, though it is debatably more plausible that COVID-19 is associated with increased health problems not detectable by early outward symptoms.
Major COVID-19 Correlates and Comorbidities

COVID-19 and Age
The COVID-19 age curve is steep, with the elderly effected most and the young effected the least.1) The more severe the case of COVID, the steeper is the age curve.

COVID-19 and Autoimmune Health
Autoimmune disorders and immunodeficiency might be described as the “primary COVID-19 correlate and comorbidity”, but is strangely underdiscussed by public health officials and the mainstream media.
COVID-19 and Blood Type
There is conflicting discussion of a correlation between COVID-19 and blood type, but evidence of a link may have thinned over time.

COVID-19 and Vitamin/Mineral Deficiencies
COVID-19 and Vitamin A Deficiency
Tepasse et al, 2021 showed significant association between Vitamin A and many endpoints of disease progression such as hospitalization, ARDS, and mortality.2)
COVID-19 and Vitamin D Deficiency
Other Risk Research
COVID-19 has been observed in some research to increase odds ratios of mortality the most with those suffering from diabetes (6.426), renal failure (4.338), and hypertension (3.261). 3)
Prion Disease
There is some evidence that prion-like domains in the spike protein enable higher affinity for ACE2 receptor binding. https://www.youtube.com/watch?v=fNFzfwLM72c&t=2s
