Yup.
In my reading, I have discovered that the body expels 13 liters of fluid when the disease is going strong—per day—until a person dies.
If you replace all that fluid, the person might live. The New England Journal of Medicine described such a case, where the fluid was replaced and the patient lived.
I’m beginning to suspect that the high fatality rate of Ebola is not so much because the virus itself is so deadly, but because the healthcare systems in Africa are so inadequate.
Cholera kills within a day or two. But with fluid replacement, most people live.
