On April 1, 2026, an expedition cruise ship departed Ushuaia, Argentina (the southernmost city on Earth), carrying 149 passengers and crew toward the most remote places on the planet.

Six days later, a passenger fell ill.

Eleven days later, that passenger was dead.

By the time anyone understood what was happening, a woman had collapsed at a Johannesburg airport gate with a boarding pass to Amsterdam in her hand. Passengers had already disembarked at islands so isolated that ships visit only a handful of times each year. Health authorities in a dozen countries were scrambling to find people they hadn’t known to look for.

The pathogen was Andes hantavirus. A virus so rarely able to spread between people that most scientists had never considered it a serious human-to-human transmission threat. The environment was a 107-meter expedition ship: a closed system designed, with no malice whatsoever, to keep people in prolonged close contact for weeks at a time.

The combination was almost catastrophic.

Near Miss is the story of how a rare virus found the one setting on Earth where it could do what it almost never does, and how the systems designed to stop it very nearly didn’t. The book reconstructs the outbreak lens by lens: the impossible diagnostic challenge facing a lone ship’s doctor in the Southern Ocean; the epidemiological logic of remote islands that are no longer truly remote; the long incubation period that lets infected travelers cross oceans before the first symptom appears; the fragile, improvised international coordination that ultimately contained what could have reached Amsterdam, London, and beyond.

This is a book about one outbreak. It is also a book about every outbreak that follows, and about the gap between the surveillance systems we have built and the ones we will need.

The rule bent. It held. Barely.
