Who is and is Not Prone to Getting Symptomatic COVID-19

Majority of people are not susceptible to getting COVID-19

Yes, the SARS-COV-2 virus is real, but not everyone gets sick when infected with it. 

If you are in a high-risk group for COVID-19 you could use prevention/prophylactic protocols or prepare to use effective, early treatment within 4 days of symptoms first appearing in order to avoid serious stage COVID-19 symptoms.

CDC's List of Higher-risk Persons include

To the CDC's high-risk list, add people with vitamin D deficienciespeople who have had recent influenza vaccinations, and people with dementia.

New Research: Sialic Acids May Contribute to Inflammation & Disease. May 13, 2021. Medcram video Dr. Roger Seheult of MedCram explains new research on Neu5Gc, a sialic acid molecule found in meat and dairy, and how it may contribute to severe COVID-19 symptoms, inflammation, oxidative stress, and certain chronic diseases, hypertension, and cancers.

Covid-19 isn’t a random killer. Only people who have one of four chronic health problems is likely to die from the virus, a major new study has confirmed. 2021. The ‘big four’ are heart disease, breathing or kidney (renal) problems, or cancer—and these risks are magnified if the person is also obese, or is suffering from several of the diseases at the same time. Age also plays a part, but again only if the patient has one of the four health problems.

Influenza Vaccinations Increase Risk for Serious COVID-19 case

A QUARTER of all UK Covid fatalities had dementia: Huge death toll among elderly is revealed. February 2021. One in four coronavirus deaths have been among those battling with dementia 

CDC study finds about 78% of people hospitalized for Covid were overweight or obese. MAR 8 2021

a December Franklin-Templeton Gallup survey showed Democrats fared much worse with the question “What are the chances that a person infected with Covid must be hospitalized?” declaring “Almost 70% of Democrats are wildly off on this key question." The U.S. public is also deeply misinformed about the severity of the virus for the average infected person. In December, we asked, “What percentage of people who have been infected by the coronavirus needed to be hospitalized?” The correct answer is not precisely known, but it is highly likely to be between 1% and 5% according to the best available estimates, and it is unlikely to be much higher or lower. We discuss the data and logic behind this conclusion in the appendix. Less than one in five U.S. adults (18%) give a correct answer of between 1 and 5%.


The young are not susceptible. E.g., here is the cumulative death rate by age for Massachussetts, the US state with the 3rd highest COVID death rate. Notice there were zero (0) deaths per 100,000 in the under 19 year old age group.

The Diamond Princess Told Us About Pre-Existing Immunity, Asymptomatic Infection and the Infection Fatality Rate. Why Were Those Lessons Ignored? March 2021

Many persons have a pre-existing immunity to COVID-19.  A review of evidence on pre-existing immunity in the BMJ

At least six studies have reported T cell reactivity against SARS-CoV-2 in 20% to 50% of people with no known exposure to the virus. ...In a study of donor blood specimens obtained in the US between 2015 and 2018, 50% displayed various forms of T cell reactivity to SARS-CoV-2.511 A similar study that used specimens from the Netherlands reported T cell reactivity in two of 10 people who had not been exposed to the virus.   In Germany reactive T cells were detected in a third of SARS-CoV-2 seronegative healthy donors (23 of 68). In Singapore a team analysed specimens taken from people with no contact or personal history of SARS or covid-19; 12 of 26 specimens taken before July 2019 showed reactivity to SARS-CoV-2, as did seven of 11 from people who were seronegative against the virus.... Reactivity was also discovered in the UK and Sweden.

Video: Blood Type and COVID 19 - Does Blood Type Matter for COVID 19? By Dr. Mike Hansen. Explains why persons with blood type O have lower risk of severe COVID disease. Blood type A has the highest risk.

Young, healthy persons are low-risk and a study published in late 2020 revealed that people with type O or Rh−negative blood may be at slightly lower risk from COVID-19.

Scientists discover why blood type may matter for COVID infection

Blood type by country

Anyone who has been infected and recovered from COVID-19 probably has lifetime immunity and increased resistance to all future SARS-COV-2 mutations.

A genetic variant inherited from Neanderthals reduces the risk of severe COVID-19. DNA variants passed on to modern humans from Neanderthals can increase as well as decrease our ability to fight SARS-CoV-2, a new PNAS study finds. The genetic variant [that decreases risk] has increased in frequency over the last millennium ... It reduces the risk of a person becoming seriously ill with COVID-19 by around 20% . .. occurs in about half of people living outside Africa and in around 30% of people in Japan...
