Why COVID-19 Makes Some People Sicker Than Others – The Atlantic
The people who get the most severely sick from COVID-19 will sometimes be unpredictable, but in many cases, they will not. They will be the same people who get sick from most every other cause. Cytokines like IL-6 can be elevated by a single night of bad sleep. Over the course of a lifetime, the effects of daily and hourly stressors accumulate. Ultimately, people who are unable to take time off of work when sick—or who don’t have a comfortable and quiet home, or who lack access to good food and clean air—are likely to bear the burden of severe disease.
Much is yet unknown about specific cytokines and their roles in disease. But the likelihood of disease in general is not so mysterious. Often, it’s a matter of what societies choose to tolerate. America has empty hotels while people sleep in parking lots. We are destroying food while people go hungry. We are allowing individuals to endure the physiological stresses of financial catastrophe while bailing out corporations. With the coronavirus, we do not have vulnerable populations so much as we have vulnerabilities as a population. Our immune system is not strong.
