You read about flu deaths every year. But it is rarely trhe flu that actually kills, the weakness caused by the flu allows other disease (usually bacterial pneumonia) to get a foothold and do the actual killing.
Stress induced by disease can’t cause a heart attack?
In the case of Ebola, not if the disease is not apparent to anyone. You are pretty much dead before you die. You die from dehydration much of the time.
Even in cases like Spanish flue or other “bleed from everywhere” diseases, you are a mess before you die. If Ebola crept up and killed her azz that quickly, we are in trouble.
If I were doing the autopsy, it would be from Australia using a robot.
