I haven't had time to respond, but this new line of logic that "they had comorbidities, so it shouldn't be counted as COVID-19" might be the single most ignorant thing I have read from the deniers yet. Let me outline what can happen when someone get seriously ill with COVID-19.
Let say our example is named "Joe". I've changed the name, but the case is real, and in no ways atypical. He's 65 years old and works as a mechanical engineer. He is overweight, but not obese. He smoked for about 20 years but quit in his 40s. He has high blood pressure, diabetes, high cholesterol and chronic kidney disease, but all are relatively mild and well controlled on medications. A few years ago, Joe had a mild heart attack, which was treated with a stent. He lost some of his cardiac capacity, but with medication and cardiac rehabilitation, he only notices this when he performs parcticularly strenuous physical activity. He remains fully employed, and has an active social life. In other words, although Joe probably isn't quite as healthy as he should be for his age, he by no means is an outlier in America, but he certainly is not at death's door. With proper medical care, he could live another 10-20 years. He recently canceled a trip to Disney World with his grandchildren due to the pandemic.
Unfortunately, Joe caught COVID-19 from one of his co-workers, a younger employee who packed into a bar as soon as they re-opened. He developed a fever and increasing severe shortness of breath. He reported to a local ER and was diagnosed with pneumonia based on a chest xray that showed his lungs were filled with fluid. Based on the severity of his symptoms and poor vital signs, Joe is hospitalized, and his COVID-19 test later returns positive. His already weakned heart now needs to pump much harder due to the illness, and his cardiac muscles start to die because the metabolic demand on them is greater than can be met with the reduced availability of blood oxygen (in medical terms, this is a type II non-ST elevation myocardial infarction, ie NSTEMI, ie, a type of heart attack). Joe goes into ventricular fibrillation, and although he is quickly revivied, the sudden reduction in cardiac output puts his already compromised kidneys into failure. Because his lungs are filled with fluid, the usual treatment for acute kidney failure, flooding the patient with IV fluid, will not work, so he needs to start emergency dialysis. As Joe's immune system tries in vain to fight the infection, his platelet count starts to drop from a dreaded complication called systemic intravascular coagulation. This throws a clot to his brain, and causes a large stroke. Recognizing the futility of further intensive care, his wife tearfully agrees to withdraw treatment, and Joe quickly sucumbs.
So, the cause of death is multi-organ failure, including kidney failure, stroke, and myocardial infarct. Although Joe wasn't in the best of health, he was living an active and productive life just before his sudden death. His underlying co-morbidities made him more vulnerable to COVID-19, but to say his death shouldn't count in the COVID numbers is absurd and a shows complete ignorance of what goes on when someone becomes severely ill.
