Interview: The razor-thin line between contagion and connection w/ Dan Taberski | from TED Health

December 29, 2025

Key Takeaways Copied to clipboard!

  • Mass psychogenic illness, or mass hysteria, is the rapid spread of real physical symptoms without an organic cause, often occurring at cultural stress points and revealing deep connections between people. 
  • The historical dismissal of women's medical issues, rooted in the term 'hysteria's' origin related to the uterus, continues to influence how women's symptoms are perceived and taken seriously by the medical system. 
  • Storytelling, approached with empathy and curiosity, is a powerful tool for reshaping discourse around complex health experiences, especially when the line between the mind and body is blurred.

Introduction to Mass Hysteria

  • Key Takeaway: The 2011 outbreak in Le Roy, New York, began with a cheerleader developing severe stuttering, evolving into tics and vocalizations resembling Tourette’s syndrome.
  • Summary: The initial case in Le Roy, New York, involved a cheerleader waking up with a severe stutter that progressed to head ticks and facial twitches. Symptoms rapidly spread to other students, leading to initial theories like a bad batch of tampons. Investigations into environmental factors like water and air quality yielded no organic cause for the outbreak.
Defining Mass Psychogenic Illness

(00:06:13)
  • Key Takeaway: Mass psychogenic illness is the spread of real physical symptoms without organic cause, often linked to underlying stress or trauma.
  • Summary: The Le Roy outbreak was diagnosed as mass psychogenic illness, or mass hysteria, a term historically linked to women (hysteria from the Greek for uterus). This phenomenon involves the rapid spread of real physical symptoms, such as neurological issues, where medical tests show no organic cause.
Modern and Historical Examples

(00:07:40)
  • Key Takeaway: Mass psychogenic illness spreads based on social connection and often manifests at cultural fissures, exemplified by the post-9/11 rash outbreak.
  • Summary: The contagion spreads among connected groups like high school students or nuns, with historical examples including medieval meowing nuns and the Salem Witches. The post-9/11 mystery rash in schools is believed to be a physical expression of collective anxiety following anthrax scares.
Fentanyl Panic as Modern Hysteria

  • Key Takeaway: Reported fentanyl overdoses among police officers, despite toxicology reports rarely confirming actual exposure, suggest a modern mass psychogenic illness vector.
  • Summary: Footage of police officers reporting tingling and passing out after proximity to fentanyl, despite toxicology reports rarely confirming actual overdose, suggests a psychogenic reaction. The use of body cams creates a feedback loop, potentially accelerating the spread of this specific contagion among male police officers.
Rose’s Experience with Tourette’s

(00:13:36)
  • Key Takeaway: For Rose, who already had Tourette’s, the presence of 19 other ticking girls worsened her symptoms due to the contagious nature of tics among affected individuals.
  • Summary: Rose, who had pre-existing Tourette’s, experienced a severe worsening of her ticks, including self-punching, because people with tick disorders tend to tick more severely around others who tick. At Tourette’s camp, where ’tick shopping’ occurs, participants embrace the shared symptoms as a form of connection.
Motivation for Investigating Hysteria

(00:19:08)
  • Key Takeaway: Dan Taberski was initially drawn to Havana Syndrome, finding it interesting that the mass psychogenic illness explanation was often avoided in favor of weapon theories.
  • Summary: The journalist’s interest began with Havana Syndrome, where the possibility of mass psychogenic illness was often dismissed. He paired the all-girls Le Roy story with Havana Syndrome (affecting mostly men) to explore the phenomenon across different demographics.
Gender and Illness Perception

(00:23:03)
  • Key Takeaway: While women historically faced medical dismissal via the ‘wandering womb’ concept, the goal is to use women’s experiences to explain universal human susceptibility to mass psychogenic illness.
  • Summary: The historical root of ‘hysteria’ involved blaming women’s bodies for unexplained issues, a problem that persists in healthcare today, especially for women of color. The reporting aimed to view susceptibility to mass psychogenic illness less as a gender issue and more as a reflection of broader human experience under stress.
Mind-Body Connection and Skepticism

(00:25:52)
  • Key Takeaway: The difficulty in accepting that mental states manifest physically stems from the mind being invisible, making psychological diagnoses feel like an act of faith.
  • Summary: People struggle to accept the mind-body connection because unconscious thoughts manifesting physically feels like magic or faith rather than observable science. Medical diagnosis of mass psychogenic illness is often a diagnosis of exclusion, requiring caution to ensure no underlying organic cause is missed.
Journalistic Approach to Uncertainty

(00:32:16)
  • Key Takeaway: The journalist’s role is to present the complexity of experiences without imposing a definitive right or wrong conclusion, allowing the audience to appreciate the mystery.
  • Summary: The reporter is comfortable presenting what people believe happened to them without validating or invalidating those beliefs, acknowledging that not everyone involved in the Le Roy event agrees on the diagnosis. The goal is to showcase the wild connection inherent in these events, rather than solving the mystery.
