Despite our wishes to be strong and independent, and despite rumors to the contrary, COVID-19 is a serious disease which severely threatens American and global communities.
Excess deaths and the severity of a pandemic
For comparison, as of August 2020, the US had experienced 204,000 more deaths than in a typical year. If you don't think COVID-19 is killing people, then you should try to explain what is killing people that wouldn't be killing them otherwise. The country's death rate through the first seven months of the year was 10% higher than typical.
The rate of cases and deaths has increased since then. By the end of October, there were 300,000 "excess deaths" compared to a typical year, even though only 216,000 were attributed to COVID-19. That 300,000 is well above the excess deaths that would be expected for the worst year in two decades. Most of the other excess deaths were likely either undiagnosed cases, or indirectly caused by COVID-19 by, for example, shortages at hospitals, overwhelmed medical workers, and people forgoing care out of fear of catching the disease. Better control of the disease by, for example, wearing masks and limiting social contact, would likely have saved many of those 300,000 lives: Either by reducing the spread of the primary disease, or by decreasing other stresses on the medical system.
It's no surprise that people who already have medical issues are at a higher risk of death due to COVID-19 than are healthy people. Comorbidities, pre-existing conditions, and complicating factors all contribute to deaths in a wide variety of scenarios: Being sick from any two diseases at once is more likely to kill you than being sick from either of them separately.
Also, folks complaining that COVID-19 is not the sole "cause of death" often listed on medical examiners' reports miss that it is often rare for a single, isolated cause to be reported. Medical examiners are trained to list everything that contributed to the death, whether it's the original disease, a pre-existing condition, or a symptom of the original disease. That is why COVID-19 is the "primary" cause of death in 94% of cases, but the "only" cause in relatively few.
