The Hot Zone

by Richard Preston

The surface of the tongue turns brilliant red and then sloughs off, and is swallowed or spat out. It is said to be extraordinarily painful to lose the surface of one’s tongue. The tongue’s skin may be torn off during rushes of the black vomit. The back of the throat and the lining of the windpipe may also slough off, and the dead tissue slides down the windpipe into the lungs or is coughed up with sputum. Your heart bleeds into itself; the heart muscle softens and has hemorrhages into its chambers, and blood squeezes out of the heart muscle as the heart beats, and it floods the chest cavity. The brain becomes clogged with dead blood cells, a condition known as sludging of the brain. Ebola attacks the lining of the eyeball, and the eyeballs may fill up with blood: you may go blind.

Droplets of blood stand out on the eyelids: you may weep blood. The blood runs from your eyes down your cheeks and refuses to coagulate. You may have a hemispherical stroke, in which one whole side of the body is paralyzed, which is invariably fatal in a case of Ebola. Even while the body’s internal organs are becoming plugged with coagulated blood, the blood that streams out of the body cannot clot; it resembles whey being squeezed out of curds. The blood has been stripped of its clotting factors. If you put the runny Ebola blood in a test tube and look at it, you see that the blood is destroyed. Its red cells are broken and dead. The blood looks as if it has been buzzed in an electric blender.

He took his eyes away from the microscope and looked around the table until he found a wooden stick that had a human eyelash glued to it with a dab of nail polish. It was a device for handling the slices. The eyelash had come from one of the women in the lab—it was generally believed that she had superior eyelashes for this kind of work, not too thick and not too thin, tapered, ending in fine points.
