laboratory for rapid virus evolution, and possibly it led to the creation of HIV. Did HIV crash into the human race as a result of the monkey trade? Did AIDS come from an island in Lake Victoria? A hot island? Who knows. When you begin probing into the origins of AIDS and Marburg, the light fails and things go dark, but you sense hidden connections. Both viruses seem part of a pattern. WHEN HE LEARNED what Marburg virus does to human being, Dr. David Silverstein persuaded the Kenyan health authorities to shut down Nairobi Hospital. For a week, patients who arrived at the doors were turned away, while sixty seven people were quarantined inside the hospital, most medical staff. They included the doctor who had done autopsy on Monet, nurses who had attended Monet or Dr. Musoke, the surgeons who had operated on Musoke, and aides and technicians who had handled any secretions from either Monet or Musoke. It turned out that a large part of the hospital's staff had direct contact with either Monet or Musoke or with blood samples and fluids that came from the two patients. The surgeons who had operated on Musoke, remembering only too well that they had been "up to the elbows in blood", sweated in quarantine for two weeks while they wondered if they were going to break with Marburg. A single human virus bomb had walked into the Casualty waiting room and exploded there, and the event had put the hospital out of business. Charles Monet had been an Exocet missile that stuck the hospital below the water line. after he fell sick, the doctors noticed a change for the better. Instead of merely lying in bed in a passive state, he became disoriented and angry and refused to take medicine. One day, a nurse was trying to turn him over in bed, and he waved his fist at her and cried, "I have a stick, and I will beat you." It was around that time that he began to get better, and after many days his fever subsided and his eyes cleared; his mind and personality came back, and he recovered slowly but completely. Today he is one of the leading physicians at Nairobi Hospital, where he practices as a member of David Silverstein's group. One day I interviewed him, and he said to me that he has almost no memory of the weeks he was infected in Marburg. "I only remember bits and pieces," he said. "I remember having major confusion. I remember, before my surgery, that I walked out of my room with my IV drip hanging out of me. I don't remember much of the pain. The only pain I can talk about is the muscle ache and the lower-back ache. And I remember him throwing up on me." Nobody else at the hospital developed a proven case of Marburg-virus disease. When a virus is trying, so to speak, to crash into the human species, the warning sign may be a spattering of breaks at different times and places. These are microbreaks. What had happened at Nairobi Hospital was an isolated emergence, a microbreak of a rain-forest virus with unknown potential to start an explosive chain of lethal transmission in the human race. Tubese of Dr. Musoke's blood went to laboratories around the world so that they could have samples of living Marburg for their collections of |
