Radiolab: "Patient Zero" (Nov 14, 2011)

Host: Jad Abumrad and Robert Krulwich
Producer: WNYC Studios
Theme: Tracing origins—of diseases, ideas, and cultural phenomena—through stories of the elusive "Patient Zero."

Episode Overview

This episode of Radiolab explores the concept of “Patient Zero”—the quest to find the first human, animal, or object to spark a chain reaction, whether it's a deadly disease, a social trend, or even a high five. The hosts journey from harrowing historical outbreaks (like Typhoid Mary and HIV/AIDS) to uplifting, quirky cultural touchstones, examining how we look for origin stories, why they seduce us, and what they can (and can't) really reveal.

Segment 1: Typhoid Mary—The Reluctant Patient Zero

[00:55–30:00]

Key Points & Story Structure

• Setting the Scene ([00:55]):
  The episode opens on North Brother Island, an abandoned quarantine site for contagious disease victims, focusing on Mary Mallon, aka “Typhoid Mary.”

  “It’s a very pretty day to be on an abandoned island where victims of contagious disease were quarantined. And one in particular lived here, died here, never believing that she was, in fact, sick and dangerous.”

• The 1906 Oyster Bay Outbreak ([02:30]):
  Typhoid fever strikes a wealthy NY family. Despite all sanitary avenues being checked, suspicion falls on the family cook, Mary Mallon, whose specialty is the uncooked Peach Melba dessert.

• Discovery of a Healthy Carrier ([06:45]):
  Public health engineer George Soper investigates and finds Mary Mallon connected to several prior outbreaks—remarkable because she’s asymptomatic.

  “She was actually the first documented case in North America of a healthy carrier, which is to say, someone who has the disease and is contagious, but never actually the symptoms.”

• Mary’s Resistance and Capture ([11:00]):
  Soper confronts Mary for samples, and she reacts furiously. Dr. S. Josephine Baker, with police, ultimately arrest Mary, who resists violently.

  “She chases him out of the building with a fork in her hand… later Josephine Baker said it was like being in a cage with an angry lion.”

• Isolation on North Brother Island ([15:00]):
  Mary is forcibly quarantined. She submits her own feces to private labs, searching for proof of innocence.

  “I have in fact been a peep show for everybody… I have been sending my own feces samples to a private lab… each one of those was negative.” — Mary Mallon’s letter

• Legal, Moral, and Social Questions ([18:30]):
  Debate erupts over the legality and ethics of Mary’s detention. She sues the city and loses.

• Release & Return ([21:25]):
  After three years, a new health commissioner releases Mary under the condition she never cooks again. Five years later, after additional outbreaks are traced back to her, she’s found working as a cook and re-quarantined for the rest of her life.

  “She was now a woman who could not claim innocence... She had broken her parole.”

• Broader Context & Gender ([25:55]):
  Hundreds of other “healthy carriers” were known, most not isolated like Mary—raising issues of scapegoating and gender.

  “Mary was the only one who they isolated in this way… I think it was more about making people feel safe than actually making them safe.”

Segment 2: AIDS and the Myth of Patient Zero

[30:03–1:06:40]

Key Points & Story Structure

• AIDS Emerges ([30:03]):
  The narrative shifts to the early days of AIDS—“the ultimate Patient Zero story.” Initial cases appear in 1981; epidemiologists seek the source.

• The Network Diagram and the Legend of Gaetan Dugas ([32:45]):
  CDC releases a diagram showing sexual contact networks; one man, numerically labeled “0,” is at the center. Journalistic accounts transform Gaetan Dugas, a French-Canadian flight attendant, into the infamous “Patient Zero.”

  “At the center of it all was that one little circle numbered 0… that was the first time you ever get the term Patient Zero.”

  “He became somewhat sinister and malicious… [he’d say] ‘I’ve got gay cancer. Now you’re gonna get it too.’” — 1988 60 Minutes special ([36:00])

• Debunking the Narrative ([40:00]):
  Science and virology reveal Dugas was not the first U.S. case—nor close to it. HIV entered the U.S. around 1966, likely via Haiti, and originated much earlier in Africa.

  “He was not Patient Zero. No, he was not the beginning point. He wasn’t. Not even close to.” — David Quammen

• Tracing the Virus’s True Origins ([43:00]):
  Scientists examine old blood/tissue samples from the 1950s and 60s (ZR59, DRC60), using genetic clock techniques to go back to “first” human infection—estimated at 1908, southeastern Cameroon.

  “The most recent common ancestor of those two specimens goes back to about 1908. That is when it started in human beings.” — Michael Worobee ([48:45])

• The “Cut Hunter Hypothesis” and the Spillover ([50:20]):
  The best theory: a Bantu hunter, wounded while butchering a chimp, caught SIV (Simian Immunodeficiency Virus), which became HIV.

  “He cuts himself and he gets blood to blood contact… That’s the moment it begins. That human is patient zero.”

• Why There? Why Then? ([52:10]):
  It’s possible the timing was “lucky”—the right virus, in a perfect colonial context of rapidly urbanizing, mobile populations.

  “All the virus has to do is get from that tiny village… to one of the new cities… and into the city. And that seems to have been the place from which the disease went global.” — David Quammen ([54:00])

• Further Back: Chimp Zero & the Viral Cocktail ([57:10]):
  SIV in chimps comes from multiple monkey viruses recombining inside a single chimp’s cell. Most viral hybrids are dead ends, but eventually, one takes off, and this “hopeful monster” then crosses to humans.

  “You get one particular mosaic virus… that landed on the exact right combination of genes that allowed it to evade the chimp’s immune system… and has been this massive and incredibly dramatic sort of tear in the fabric of humanity.” — Nathan Wolfe ([1:01:30])

• Multiple Spills, Viruses Always “Knocking” ([1:03:55]):
  There are multiple HIVs; only one caused the global pandemic, but “spillover” is a frequent event. Scientists like Nathan Wolfe now monitor for these in real time, using digital surveillance and genetic testing.

  “If you want a patient zero, really clear patient zero, it’s some of these individuals that have been infected with these viruses. The real question is: how do we stop patient zeros?” — Nathan Wolfe

Segment 3: The Spread of the High Five—Tracing a Cultural Meme

[1:07:30–1:40:00]

Key Points & Story Structure

• The Quest for the First High Five ([1:07:48]):
  Writer John Moallam traces a viral press release crediting basketball player Lamont Sleet as the inventor; it turns out to be a hoax dreamed up by a fake “National High Five Day” team purely to test the media’s gullibility.

  “Is the Lamont Sleet story true?... There was a pause, and he said: no. Frankly, we’ve been waiting for someone to ask. We thought no one would ever ask. It’s not true. We wanted to see if the media would… run with it.” — Greg Harrelledge ([1:22:10])

• The Real Story—Glenn Burke and Dusty Baker ([1:11:30]):
  Moallam shares a more credible founding tale: gays rights pioneer and LA Dodgers outfielder Glenn Burke initiates the first known high five with teammate Dusty Baker in 1977. Burke’s personal story is bittersweet—ostracized for being gay, his career and life ended tragically.

  “Think about the feeling you get when you give someone the high five. I had that feeling before everybody else did.” — Glenn Burke ([1:19:00])

• Counting Other Claims ([1:25:00]):
  Competing claims include Derek Smith and Wiley Brown of the 1980 Louisville basketball team, volleyball coach Kathy Gregory in the 1960s, and even a 1955 French movie scene. The hosts and guests reflect on why we long for a single origin, and the fantasy of a clean Patient Zero.

• The Real Miracle: Restoring Connection ([1:32:00]):
  The most powerful “high five” is not historical, but technological: Tim, a paralyzed man, uses a neural implant to connect a robotic hand to his thoughts and “high fives” his girlfriend for the first time in seven years.

  “I was able to put this piece of machinery that looked very similar to a hand on her hand. Not only did I just touch her, but I pushed into her hand. It was weird, too, because the hand was actually warm.” — Tim ([1:35:50])

Segment 4: Who Invented the Cowboy Hat?—The Illusion of a Sole Inventor

[1:40:05–1:51:20]

Key Points & Story Structure

• Origin Myths ([1:40:30]):
  Science writer Johnny Hughes investigates the cowboy hat’s beginnings, offering three origin stories:

  1. The Stetson Story: John B. Stetson designs it in 1865, based on a vision of practicality.
  2. Evolution by Community: Cowboys’ habits and needs shape the hat’s design over years—dents, brims, and wear become trends that hatmakers rack up.
  3. The Environmental Story: No one “invents” the hat—the environment (weather, prairie, sun) shapes it unconsciously, like natural selection.

  “The environment created the hat. The wind created the hat. The rain, the sun, the snow, the weather created those hats.” — Johnny Hughes ([1:47:00])

• Reflection on Storytelling and Origin Stories ([1:49:00]):
  The hosts discuss how the search for a single creator or first cause is often a narrative convenience, not historical truth, and that real stories are always more tangled.

  “As storytellers, we’re always trying to get to moments, get down to the particular person… That’s what we want as storytellers. So in some sense your scenario three is like the death of story. In some sense, it’s the anti story.” — Jad Abumrad

Notable Quotes & Memorable Moments

• On scapegoating and Patient Zero:

  “We want a tidy story—one person to blame, one hero to credit, one culprit to isolate. But reality's more complicated.” ([Whole episode, recurring theme])

• On the gendered politics of Typhoid Mary:

  “Mary was the only one... isolated in this way. I think it was more about making people feel safe than actually making them safe.” ([27:30])

• On viral evolution's randomness:

  “A blue moon after a blue moon after a blue moon.... you get one particular mosaic virus... that allowed it to evade the chimp’s immune system.” — Nathan Wolfe ([1:01:30])

• On our appetite for origin stories:

  “Who in this room wants the gay guy to be the inventor? I want the gay guy. Yeah... It’s the better story of the two. And something in me says, just go with the narrative winner.” ([1:29:00])

• Technological hope:

  “It still kind of boggles my mind when I think about it.” — Tim, on experiencing human touch via robot hand ([1:36:00])

Overall Tone and Style

Radiolab’s trademark is in full force: narrative journalism, curiosity, humor, empathy, and innovative sound design. The hosts maintain a conversational, often playful voice, while thoughtfully confronting deep ethical and philosophical issues.

Conclusion

“Patient Zero” asks whether it is ever really possible—or even desirable—to pin complex events to a single origin. From viruses to baseball celebrations to hats, the truth is always messier, more collective, and shaped as much by context as by individuals. The narrative of “firsts” may comfort us or help us organize the world, but, as Radiolab reminds us, nothing begins in a vacuum.
