Hantavirus
The trail ended at a wire gate Hendrik had to lift off its post, and beyond the gate the Patagonian scrubland opened toward the granite. Forty-three years of designing water treatment plants in Rotterdam had taught him that clean water was the gift you stopped noticing first. He had come to Aysén Region to notice things again.
He pitched his tent beside a stream that ran cold from the snowfields. The silence pressed against his eardrums. No traffic, no machinery, no voices from neighboring campers, only wind and the occasional call of an austral parakeet. He cooked pasta on his camp stove and watched the sky go from blue to purple to black. The Southern Cross wheeled overhead in air no city had touched.
The long-tailed pygmy rice rat emerged from the root system of a southern beech after midnight. She was small enough to sit in a child’s cupped hands. The scent of food drew her forward on delicate paws. She had raised three litters that summer, and winter was coming.
The tent’s vestibule held a stuff sack hanging from a pole, supposedly secure. The cord had loosened during the day’s hiking. She climbed the nylon wall, her claws finding purchase in the weave, and chewed through a corner of plastic with teeth designed for seeds. Almonds scattered across the floor. She ate methodically, pausing to clean her whiskers, her small bladder emptying as she fed. Droplets fell onto the crackers below.
When she had eaten her fill, she retreated into the root maze. Behind her the food bag hung askew, its contents scattered.
Hendrik woke to gray dawn and discovered the damage. Droppings on the breakfast supplies, teeth marks through the dried fruit. He swore quietly in Dutch and picked through the mess, salvaging what looked untouched. The nearest resupply was two days behind him, and he had planned this route to the edge of the map for that reason.
He ate the crackers and the almonds, brushing aside what needed brushing. The morning coffee tasted the same as always.
Three days later he stood on the dock at Ushuaia, watching stevedores load the last pallets onto the MV Hondius. The ship rose white from waters that had carried Magellan and Darwin and every fool who had thought the bottom of the world was empty. Two hundred passengers would venture through the south Atlantic for emperor penguins and blue whales.
A fever had been building behind his eyes since yesterday. The deep ache in his calves felt like the flu he caught most winters at the office. Travel exhaustion, he assumed, the price of moving from windswept rock to a port town in two days. He pulled his jacket tighter and joined the boarding queue.
A young woman in a blue Hondius fleece was checking passports and reading from a laminated card.
“Any fever, cough, or shortness of breath in the last forty-eight hours?”
“No,” Hendrik said.
“Contact with rodents, bats, or wild animals?”
He thought of the food bag, the droppings he had brushed aside. The question had a tone he recognized from his own industry, the tone of a checklist designed by people who would never have to read it aloud. Saying yes would mean a clinic in Ushuaia, a quarantine room, a refund form, the cruise leaving without him.
“No.”
She stamped his card and waved him through. The gangway led him into a warm lobby where passengers were already trading stories. A German couple had hiked Torres del Paine. An American family compared restaurants in Buenos Aires. Hendrik found himself next to a retired teacher from Melbourne who had always wanted to see Antarctica.
The ship’s horn sounded their departure. Hendrik felt the cough rising from somewhere deep in his chest and covered his mouth with the back of his hand.
It came out small, dry, polite.
