SARS-CoV-2 needs cholesterol to invade cells and form mega cells:
People taking cholesterol-lowering drugs may fare better than others if they catch the novel coronavirus. A new study hints at why: the virus relies on the fatty molecule to get past the cell's protective membrane.
To cause COVID-19, the SARS-CoV-2 virus must force its way into people's cells—and it needs an accomplice. Cholesterol, the waxy compound better known for clogging arteries, helps the virus open cells up and slip inside, Howard Hughes Medical Institute Investigator Clifford Brangwynne's lab reports.
Without cholesterol, the virus cannot sneak past a cell's protective barrier and cause infection, the team writes in a preprint posted to bioRxiv.org on December 14, 2020. The work, which recreated the early stage of infection in lab-grown cells, has not yet undergone the scientific vetting process of peer review.
"Cholesterol is an integral part of the membranes that surround cells and some viruses, including SARS-CoV-2. It makes sense that it should be so important for infection," says Brangwynne, a biophysical engineer at Princeton University.
The finding might underlie the better health outcomes seen in COVID-19 patients taking cholesterol-lowering drugs known as statins, he adds. Although scientists haven't yet established the mechanism responsible, this study and another published last fall suggest the drugs prevent SARS-CoV-2 from getting into cells by denying it cholesterol.
[...] Brangwynne says it's not clear yet whether or not syncytia play a major role in the progression of COVID-19. But, his team writes, the discovery of cholesterol's contribution could help scientists fight the disease. "Our findings underscore the potential utility of statins and other [similar] treatments."

Everyone's blood contains cholesterol, so a low cholesterol individual might experience a slow enough infection that their immune system can counter it before it becomes rampant. We've known for a year now that obesity is a huge risk factor for death when contracting SARS-CoV-2. Not like we needed yet another reason to keep ourselves fit, a healthy weight, and low-fat.
Also get your vaccines, people, as soon as they are offered. I got my second dose of the Pfizer vaccine last week. I felt sick for about a day after the 2nd shot. It came on fast and went away fast; like having a cold without actually having a cold. And keep wearing masks.

Oh, fuck off. I'll wear a mask alright, but don't you touch my steaks, chips and beer, you heathen. (grin)

The way I see it, if my arteries are choked up, then my heart gets more exercise...

Fat is good for your arteries--makes them hard as rocks!

fat is good for you, fucktard. As long as you're not constantly supplying the body with carbs that keep the fat from ever being burned.

stfu, you disgusting slave.
"And keep wearing masks. "
fuck you bitch. talk to me about it in meatspace and i'm going to fuck you up.
