Here we show loading cells with cholesterol from blood serum using the cholesterol transport protein apolipoprotein E (apoE) enhances the endocytic entry of pseudotyped SARS-CoV-2. Super resolution imaging of the SARS-CoV-2 entry point with high cholesterol showed markedly increased apparent diameter (~10% to 100 nm) and almost twice the total number of viral entry points. The cholesterol concomitantly traffics angiotensinogen converting enzyme (ACE2) to the viral entry site where SARS-CoV-2 docks to properly exploit entry into the cell. Furthermore, we show cholesterol enhances binding of SARS-CoV-2 to the cell surface which increases association with the endocytic pathway. Decreasing cellular cholesterol has the opposite effect. Based on these findings and known loading of cholesterol into peripheral tissue cholesterol during aging and inflammation, we build a cholesterol dependent model for COVID19 lethality in elderly and the chronically ill.
MORE evidence emerges that smokers are protected from coronavirus: Italian study finds them FIVE TIMES less likely to end up in hospital (but almost twice as likely to die if they do)
esearchers have uncovered more evidence that smokers could be protected from the deadly coronavirus. Fewer than five per cent of 441 COVID-19 patients who needed to be admitted to an Italian hospital were smokers. The scientists described it as a 'very low' number, given that a quarter of the general population are known to be hooked on cigarettes. It suggests smokers are less likely to catch the disease - a theory that has emerged over the past few weeks from several global studies. But once smokers are in hospital, they may be more likely to see their disease rapidly progress and lead to death, according to some evidence. The new study found half of infected smokers died - compared to 35 per cent of the rest of the patients. Experts are struggling to knock down mounting evidence that suggests an apparent protective effect from cigarettes, which has been described as 'weird'.

Are you going to elaborate or are you just posting Death ?
here is the real number
www.cdc.gov...
The overall Mortality rate of Covid-19 is has been substantialy lowered since adding the actual number of cases into the equation , meaning this virus has been here for much longer than previously thought.
NOTE: Number of deaths reported in this table are the total number of deaths received and coded as of the date of analysis and do not represent all deaths that occurred in that period.
*Data during this period are incomplete because of the lag in time between when the death occurred and when the death certificate is completed, submitted to NCHS and processed for reporting purposes. This delay can range from 1 week to 8 weeks or more, depending on the jurisdiction, age, and cause of death.
1Deaths with confirmed or presumed COVID-19, coded to ICD–10 code U07.1.
....
5 Deaths with confirmed or presumed COVID-19, pneumonia, or influenza, coded to ICD–10 codes U07.1 or J09-18.9.

I want to ask something.
Are there scientific data that this virus damages organs permanently? If yes, does it damage even those who recovered lightly?
Thanks..

Would that be because they have to stop smoking in the Hospital?

That's strange given that half the lung transplants use smokers lungs , and they all have the survival rate the same as non smokers. www.independent.co.uk...
