Ebola (and Marburg) multiplies so rapidly and powerfully that the body’s infected cells become crystal-like blocks of packed virus particles. These crystals are broods of virus getting ready to hatch from the cell. They are known as bricks. The bricks, or crystals, first appear near the center of the cell and then migrate toward the surface. As a crystal reaches a cell wall, it disintegrates into hundreds of individual virus particles, and the bloodlings push through the cell wall like hair and float away in the bloodstream of the host. The hatched Ebola particles cling to cells everywhere in the body, and get inside them, and continue to multiply. It keeps on multiplying until areas of tissue all through the body are filled with crystalloids, which hatch, and more Ebola particles drift into the bloodstream, and the amplification continues inexorably until a droplet of host’s blood can contain a hundred million individual virus particles.
After death, the cadaver suddenly deteriorates: the internal organs, having been dead or partially dead for days, have already begun to dissolve, and a sort of shock-related meltdown occurs. The corpse’s connective tissue, skin, and organs, already peppered with dead spots, heated by fever, and damaged by shock, begin to liquefy, and the fluids that leak from the cadaver are saturated with Ebola-virus particles.
When it was all over, the floor, chair, and walls in Sister M.E’s hospital room were stained with blood. Someone who saw the room told me that after they took her body away for burial (wrapped in many sheets), no one at the hospital could bear to go into the room to clean it up. The nurses and doctors didn’t want to touch the blood on the walls and were frankly fearful of breathing the air in the room, too. So the room was closed and locked, and remained that way for days. The appearance of the nun’s hospital room after her death may have raised in some minds one or two question about the nature of the Supreme Being, or, for persons not inclined to theology, the blood on the walls may have served as a reminder of the nature of Nature.
No one knew what had killed the nun, but clearly it was a replicating agent, and the signs and symptoms of the disease were not easy to consider with a calm mind. What also did not lead to calm thoughts were rumors coming out of the jungle to the effect that the agent was wiping out whole villages upriver on the Congo. These rumors were not true. The virus was hitting families selectively, but no one understood this because the flow of news coming from upriver was being choked off. Doctors at the hospital in Kinshasa examined the nun’s case and began to suspect that she might have died of Marburg or a Marburg-like agent.
Then Sister E.R., the nun who had traveled with Sister M.E. during the drive to Bumba and the plane flight to Kinshasa, broke with l’eoudenue. They put her in a private room at the hospital, where she began to die with the same signs and symptoms that had preceded Sister M.E.‘s death.
There was a young nurse at the Ngaliema Hospital named Mayinga N. (Her first name was Mayinga and her last name is given as N.) Nurse Mayinga had been caring for Sister M.E. when the nun had died in the bloodstained room. She may have been splattered with the nun’s blood or with black vomit. At any rate, Nurse Mayinga developed a headache and fatigue. she knew she was becoming sick, but she did not want to admit to herself what it was. She came from a poor but ambitious family, and she had received a scholarship to go to college in Europe. What worried her was the possibility that if she became ill, she would not be allowed to travel abroad. When the headache came upon her, she left her job at the hospital and disappeared. She dropped out of sight for two days. During that time, she went into the city, hoping to get her travel permits arranged before she became visibly sick. On the first day of her disappearance—the date was October 12, 1976—she spent a day waiting in lines at the offices of the Zairean foreign ministry, trying to get her papers straight.
The next day, October 13, she felt worse, but instead of reporting to work, again she went into the city. This time, she took a taxi to the largest hospital in Kinshasa, the Mama Yemo Hospital. By now, as her headache became blinding and her stomach pain increased, she must have been terribly frightened. Why didn’t she go to the Ngaliema Hospital to seek treatment where she worked and where the doctors would have taken care of her? It must have been a case of psychological denial. She did not want to admit, even to herself, that she had been infected. Perhaps she had a touch of malaria, she hoped. So she went to Mama Yemo Hospital, the hospital of last resort for the city’s poor, and spent hours waiting in a casualty ward jammed with ragged people and children.
I can see her in my mind’s eye—Nurse Mayinga, the source of the virus in the United States Army’s freezers. She was a pleasant, quiet, beautiful young African woman, about twenty years old, in the prime of her life, with a future and dreams, hoping somehow that what was happening to her could not be happening. They say that her parents loved her dearly, that she was the apple of their eye. Now she is sitting in the casualty ward at Mama Yemo among the cases of malaria, among the large-bellied children in rags, and no one is paying any attention to her because all she has is a headache and red eyes. Perhaps the fact that she is crying has made her eyes red. A doctor gives her a shot for malaria and tells her that she should be in quarantine for her illness. But there is no room in the quarantine ward at Mama Yemo Hospital; so she leaves the hospital and hails another taxi. She tells the driver to take her to another hospital, to University Hospital, where perhaps the doctors can treat her. But when she arrives at University Hospital, the doctors can’t seem to find anything wrong with her, except for possibly some sign of malaria. Her headache is getting worse. She is sitting in the waiting room of this hospital, and as I try to imagine her there, I am almost certain she is crying. Finally she does the only thing left for her to do. She returns to Ngaliema Hospital and asks to be admitted as a patient. They put her in a private room, and there she falls into lethargy, and her face freezes into a mask.
News of the virus and what it did to people had been trickling out of the forest, and now a rumor that a sick nurse had wandered around Kinshasa for two days, having face-to-face contact with many people in crowded rooms and public places, caused a panic in the city. The news spread first along the mission grapevine and through government employees and among the diplomats at cocktail parties, and finally the rumors began to reach Europe. When the story reached the offices of the World Health Organization in Geneva, the place went into a full-scale alert. People who were there at the time said that you could feel fear in the hallways, and the director looked like a visibly shaken man. Nurse Mayinga seemed to be a vector for an explosive claim of lethal transmission in a crowded third-world city with a population of two million people. Officials at the WHO began to fear that Nurse Mayinga would become the vector for a world-wide plague. European governments contemplated blocking flights from Kinshasa. The fact that one infected person had wandered around the city for two days when she should have been isolated in a hospital room began to look like a species-threatening event.
President Mobutu Sese Seko, the maximum leader of Zaire, sent his army into action. He stationed soldiers around Ngaliema Hospital with orders to let no one enter or leave except doctors. Much of the medical staff was no under quarantine inside the hospital, but the soldiers made sure that the quarantine was enforced. President Mobutu also ordered army units to seal off Bumba Zone with roadblocks and to shoot anyone trying to come out. Bumba’s main link with the outside world was the Congo River. Captains of riverboats had heard about the virus by this time, and they refused to stop their boats anywhere along the length of the river in Bumba, even though people beseeched them from the banks. Then all radio contact with Bumba was lost. No one knew what was happening upriver, who was dying, what the virus was doing. Bumba had dropped off the face of the earth into the silent heart of darkness.
