A Man's Illness After Visiting a Cave

In the shadow of Mount Elgon, a massive extinct volcano on the border of Kenya and Uganda, a Frenchman named Charles Monet lived a solitary life. An amateur naturalist who preferred the company of birds and monkeys to people, he spent his days maintaining water machinery for a sugar factory. His quiet life took a fateful turn during the Christmas season of 1979 when he decided to camp on the slopes of the great volcano and visit Kitum Cave, a vast cavern carved into the rock by generations of elephants seeking salt. Inside, Monet walked through a petrified forest of stone trees and navigated floors slick with the guano of thousands of bats. In this dark, damp environment, he encountered something invisible and ancient.

Seven days after his visit, a horrifying transformation began. It started with a throbbing headache that no aspirin could dull, followed by severe backache and a spiking fever. By the third day, Monet was gripped by intense vomiting and a terrifying physical shift. His face lost all animation, setting into a frozen, expressionless mask. His eyes turned a brilliant, bruised red, and his skin became yellowed and speckled with starlike spots. As his memory eroded and he grew sullen and resentful, his colleagues, alarmed by his zombie-like appearance, sent him to a hospital. When local doctors found no cure, Monet—still mobile but rapidly deteriorating—boarded a crowded commuter flight to Nairobi. He had become a human virus bomb, carrying a highly amplified load of a lethal agent into the heart of a major city.

During the flight, the destruction of Monet's internal systems reached a breaking point. The virus had saturated every cell of his host, a process known as extreme amplification, and was attempting to convert his body into a mass of virus particles. He began to suffer from "black vomit," a mixture of arterial blood and liquefied stomach lining, as his blood refused to clot and leaked into his internal organs. Upon arriving at Nairobi Hospital, Monet collapsed in the waiting room and suffered a catastrophic hemorrhage from every orifice. This "crashing" is the final stage of the infection, where the virus, having destroyed its current host, seeks a new one.
