Final answer:
In 'The Hot Zone,' Charles Monet and Peter Cardinal's paths crossed at Nairobi Hospital, where both were treated after visiting Kitum Cave.
Step-by-step explanation:
In the book The Hot Zone, the paths of Charles Monet and Peter Cardinal crossed at the Nairobi Hospital. Monet, who became ill after visiting Kitum Cave, was taken to Nairobi Hospital, a place where Peter Cardinal would also be treated later on.
Cardinal, a young boy, visited Kitum Cave as well, possibly encountering the same deadly virus that had struck Monet. Their tragic stories are connected through the hospital, serving as a nexus for identifying and understanding the emergence and spread of viral hemorrhagic fevers.
The connection highlights the global nature of infectious diseases and the importance of vigilance when dealing with unknown pathogens.
