I think I read once long ago that anytime someone with diabetes dies, it is ALWAYS ruled as a complication of diabetes. I assume something like a murder might be an exception. Does that sound right or did my pea-sized brain get mixed up on something?Counting people who die of "other causes" while suffering from the COVID-19 virus is consistent with standard medical practice. There are numerous reasons for this, but basically suffice it to say that no disease exists in a vacuum.
When I was in school they quoted us that 80% of people over 80 who have a long bone fracture never make it out of the hospital. They die from strokes, heart attacks, pneumonia or a number of other complications - seldom anything directly related to the fractured hip or leg. The reasons have to do with inflammation, stress on already-weak body systems, etc. These people still get counted in epidemiological studies as deaths related to their fracture or to surgeries to repair things - surgeons frequently hate that these numbers get attributed to their surgical complications, and I understand why, but it's the way it is done, consistently.
Other countries were not counting them as COVID-19 deaths to keep their numbers down... the US is doing it to keep consistency with normal medical recordkeeping. COVID-19 can cause you to have a heart attack, if you have the underlying risk factors that make you prone to one already - atherosclerotic disease, primarily. Maybe you would have gone another year or two before having it, but it is still attributable to the infection triggering a cascade of events.
