Every day in the UK covid news cycle brings a new round of covid statistics. Numbers of positive tests, numbers of hospitalisations, numbers of fatalities. And yet these statistics rarely seem to be given any context. Some of the covid risk factors are by now very well known, but when the daily covid statistics are presented in the UK MSM, there is little to no mention of the circumstances of hospitalisations and fatalities.
So what are some of the risk factors?
Obesity:
Obesity as a risk factor has been known about almost from the very start. And considering that large proportions of the Western population are overweight, it's hardly surprising that many people in the US and the UK are vulnerable to covid.

Age:
The vulnerability of elderly people has also been known about almost from the very start. In the UK the average age of a covid fatality is slightly greater than the (pre-covid) average life expectancy.
Average age of those who had died with COVID-19
Ethnicity and heritage:
There is some theoretical evidence that the covid virus may bind more strongly to the ACE2 receptor in people of certain ethnicities and heritages. It's a theoretical study, but if it's proved in the real world, then Europeans appear to be among the most vulnerable, and Ashkenazi Jews the least vulnerable.

Kidney function:
COVID-19 and chronic kidney disease: a comprehensive review
Kidney impairment in hospitalized patients with SARS-CoV-2 infection is associated with increased in-hospital mortality and worse clinical evolution, raising concerns towards patients with chronic kidney disease (CKD).
Sickle cell disease:
Sickle cell disease and COVID-19: Susceptibility and severity
The obtained results should be interpreted, considering low cases from sub-Saharan people, younger age of SCD patients compared to general population, a bias toward registry of the more severe form of disease, the effect of pre-existing comorbidities with multisystem organ damage, and the role of health socio-economic determinants.
Blood group:
The effects of blood group types on the risk of COVID-19 infection and its clinical outcome
The results of the present study suggest that while the blood group A might have a role in increased susceptibility to the COVID-19 infection, the blood group O might be somewhat protective. However, once infected, blood group type does not seem to influence clinical outcome.
