The Virus Hunter

By Tom Clynes

Author’s note: I often include this story in my keynote presentations. In terms of intrigue, it’s got just about everything: an exotic location, scary diseases and a protagonist whose efforts may very well prevent the next smallpox or Ebola from gaining a foothold in human bloodstreams.

On my journey with Nathan Wolfe and his team into the very jungle that produced the HIV virus, I could see how logging and bush-meat hunting is bringing humans deeper into once-isolated regions that have a history of spawning deadly pandemics. Meanwhile, society has stacked the decks in favor of opportunistic microbes, with our closely packed cities, our changing climate and our growing numbers of elderly.

Like many of the world-changers I’ve met, Wolfe has the conviction and tenacity to follow through in the face of challenges that would turn back most others. This is one of the most logistically challenging environments on earth, but as Wolfe tells his team, “If nothing is going wrong, it means we’re not asking tough enough questions.”

 


HIV, Ebola, and the vast majority of other killer diseases have passed from animals to humans. Virologist Nathan Wolfe is searching for the next AIDS before it makes the leap — and is revolutionizing the way the world tries to control diseases in the process.

It’s nearly midday when Brice Bidja steps out of the tangled forest surrounding the African village of Messok in southeastern Cameroon, gripping a Russian 12-gauge shotgun in one hand and the limp body of a mustached monkey in the other. Bidja usually returns alone after his hunts, but on this morning a handful of foreigners tags along with him as he approaches his mud-brick hut. Among the researchers, logisticians, and documentarians is American virologist Nathan Wolfe.

Wolfe stands just outside as the others duck through the low doorway; inside, the glare of the tropical sun gives way to an easy reddish glow of firelight on the faces of Bidja’s wife Sandrine and their two small children. Bidja sets the monkey down on a palm frond and pulls out a sheet of filter paper provided by Wolfe’s organization, the Global Viral Forecasting Initiative (GVFI). Sandrine crouches and picks up a machete, then slices off one of the animal’s front legs and holds it over the paper, aiming the dripping blood at five printed circles. Once the targets are saturated, the hunter tucks the blood sample into a ziplock bag filled with silica gel packets and hands the bag to one of Wolfe’s colleagues. The group will run tests later to see if the animal that Bidja and his family would soon devour is infected with a particularly nasty virus that could jump to humans, ultimately becoming the next deadly pandemic.

Sandrine thrusts the monkey’s leg into the flames, perfuming the hut with burnt hair and skin. She sets it aside and continues the butchery as the foreigners come in closer with their cameras and notepads, documenting the blade’s passage through legs and tail and neck. At the doorway, Bidja chats with Wolfe, their simple French mixing with the sounds of splitting bones and separating tendons. Sandrine begins to open the monkey’s rib cage with sharp hacks of her machete, each of which unleashes a fine spray of blood. It’s too much for one of the visitors, who darts outside and makes a panicked reach into her backpack, pulling out a bottle of antibiotic gel.

“Oh good, you brought hand sanitizer,” Wolfe says, exaggerating a stifled smirk. “That’ll protect you, don’t worry.”

Children in southeastern Cameroon play with organs of a mustached monkey, recently hunted and butchered for the family dinner. Virologists analyze blood samples from animals like this, and from human hunters, to detect and prevent outbreaks of any viruses which might be transferred from animals to humans.

Meanwhile, Sandrine uses a smaller knife to finish readying every part of the money, except the entrails, for her family’s use. Seeing the children growing restless, she reaches into the animal’s chest cavity and cuts out its heart and liver. She tosses the floppy organs to the kids, who roll them in their hands like Silly Putty, showing them proudly to Wolfe.

Solidly built, with curly hair and plump, whiskered cheeks, Wolfe, 38, is at the muddy-boots vanguard of an ambitious movement that seeks to shift the way the world approaches disease control, from containing outbreaks to launching preemptive strikes against emerging viruses. “If we look at AIDS or smallpox or Ebola, or any of the really bad shit that has emerged over the past century,” says Wolfe, “the vast majority of these pathogens passed from animals to us. What we’re trying to do now is get upstream, way upstream, and catch the next HIV before it can explode into a killer pandemic.”

How Can 6 Million Acres at Denali Still Not Be Enough?

By Tom Clynes

Author’s Note: After a half-year of brainstorming about National Geographic Magazine‘s yearlong celebration of America’s national parks, the magazine’s editors offered me the pick of the litter.

The choice was easy. Denali National Park, the crown jewel of America’s park system, offered a range of possibilities broad enough to be a world unto itself. It also offered some formidable challenges. I quickly realized that the normal conventions of outdoor reporting wouldn’t cut it in this vast wilderness, which is cut by only one 92-mile-long road.

I would spend a total of five weeks walking, skiing, flying and dog-sledding through the park’s spectacular terrain, during the extremes of the Alaskan winter and summer. These explorations yielded enough stories and images and controversies to fill dozens notebooks and photo data cards.

In the end, only a small fraction of this material fit into NatGeo’s 28-page feature story, leaving plenty of adventures to share for the first time with audiences at my upcoming talks and presentations.


The icon of Alaska’s wilderness symbolizes the tension between preservation and use at U.S. national parks.

Park rangers here call the high season—from June through early September, when Denali National Park and Preserve hosts the majority of its 500,000 annual visitors—the “hundred days of chaos.” Indeed a midsummer morning at the park’s Wilderness Access Center, located at the start of Denali’s fabled 92-mile-long Park Road, can feel a bit like rush hour at Manhattan’s Port Authority Bus Terminal. Loudspeakers announce bus boarding times, and visitors from many nations crowd the ticket counter.

Most of Denali’s visitors are cruise ship passengers who see the park and its prolific wildlife largely through bus windows. “But if you’re seeking solitude, it’s not hard to find,” says ranger Sarah Hayes, who helps backpackers and hikers prepare for their adventures. “We’ve got six million acres of mostly trailless lands where wild animals roam undisturbed. And it’s accessible to anyone who hops off the bus.”

As my bus rolls out, noses press against windows, hands clutch cameras, and people speaking half a dozen different tongues excitedly speculate about wildlife sightings. I ask several passengers what’s on their wish list. “A moose!” “A grizzly!” “Caribou!” “A wolf!”

At the five-mile mark we spot our first animal. “Squirrel!” a kid yells, bringing the bus to laughter. After the 15-mile mark, the road turns to dirt and empties of cars. A few miles farther along the trees disappear. As the distant peaks of the Alaska Range come into view, the scale of this kingdom of nature becomes apparent. The driver slows down.

“It’s been hiding for two weeks now,” he says, wheeling the vehicle through a tight turn. “But there’s a pretty good chance that today …” As the towering mountain comes into hazy view, a dozen voices sing out, “Denali!”

Rising 20,310 feet above sea level, North America’s tallest peak is a stunning sight, although in warm weather its slopes are often shrouded in clouds. The mountain was a big part of the legend and lore of the Athabaskan-speaking people who gave it the name Denali, meaning Tall One. In 1896 gold prospector William Dickey renamed it Mount McKinley in honor of Ohio politician William McKinley, a staunch champion of the gold standard who one year later would become the nation’s 25th president. For decades Ohio’s congressional delegation successfully blocked attempts to rename the mountain. Then last summer the Obama Administration used its executive power to restore the original name.

Seeing the mountain, spotting a grizzly, or catching a glimpse of a wolf are the top three reasons people give for coming to Denali. As recently as 2010, a visitor stood a better chance of seeing a wolf in the wild than seeing the elusive Tall One, which is visible on just one in three summer days. But since 2010 the number of wolf sightings has plunged. According to a study of wildlife viewing opportunities along the Park Road, observers recorded wolf sightings on only 6 percent of trips in 2014—down from 45 percent in 2010. Park biologists report that the number of wolves inside the park has dropped from more than 100 a decade ago to fewer than 50 last year. I came to Denali, in part, to discover why.
