XVI. CONTAGION — SYMPTOMS THAT SPREAD WITHOUT A PATHOGEN
Not religious, but culturally specific. The afflictions take their form from local beliefs about the body, and change form when the beliefs do.
Who led it
No leader. The 1967 outbreak was ended by the SINGAPORE MEDICAL ASSOCIATION and the MINISTRY OF HEALTH.
What it worshipped and taught
KORO is the sudden conviction that the genitals are retracting into the body and that death will follow, producing genuine panic and physical symptoms. AMOK is a sudden explosive assault after a period of brooding withdrawal, followed by exhaustion and amnesia; English took the phrase RUNNING AMOK from it. LATAH is an extreme startle response with echoed speech and movement and momentary automatic obedience.
Who was in it
The 469 recorded Singapore cases and the many not recorded; the Singapore Medical Association; the traditional practitioners whose caseload was never counted.
How it ended, or where it stands
KORO EPIDEMICS STILL OCCUR where the underlying belief is current. The vocabulary of classification has changed; the phenomenon has not.
The dead
NO DEATHS were recorded in the Singapore epidemic, and the public statement that nobody had died was itself the intervention that stopped it.
Of note
THE 1967 EPIDEMIC IS THE MOST ACTIONABLE CASE IN THIS ERA, BECAUSE SOMEBODY STOPPED ONE. Tanganyika closed a school and spread the outbreak across a district (167). Singapore named the mechanism publicly, in the press and on television, with medical authority behind it, AND IT ENDED IN DAYS. The first reassurance, from an agriculture ministry, had made it worse; the one that worked came from doctors. The difference between those two responses is the whole practical content of this subject.
WHY THIS ENTRY SITS IN A DOSSIER ABOUT CULTS. Koro, amok and latah demonstrate that DISTRESS DOES NOT ARRIVE WITH A FIXED SHAPE. It is poured into whatever container the culture provides. A 16th-century Rhinelander who believed a saint could compel dancing danced (164). A 1967 Singaporean who had heard the pork rumour experienced retraction. A 2021 teenager who watched tic videos ticced (169). SAME MECHANISM, DIFFERENT VOCABULARY EVERY TIME.
AND THAT IS PRECISELY WHAT A HIGH-CONTROL GROUP SUPPLIES TO ITS MEMBERS. It hands them a complete account of what they will feel, what those feelings mean, and what will happen if they doubt. The rest of this dossier is full of people who then reliably experienced it. THE GROUPS DID NOT NEED A SPECIAL TECHNIQUE. They needed a story and a closed room, and human beings supply the rest.
A CAUTION AGAINST CONDESCENSION, WHICH THIS SUBJECT INVITES. These are not the quaint afflictions of distant people. The Western equivalents are in 166, 169 and arguably 170. What differs is the content, not the capacity.

Its timeline
- 1967 SWINE FEVER in Singapore leads to the vaccination of pigs against it.
- 29–31 OCTOBER 1967 A NEWSPAPER REPORTS THAT PEOPLE HAVE DEVELOPED KORO FROM EATING PORK FROM VACCINATED PIGS. Cases reach the Singapore General Hospital emergency unit on 31 October, overwhelmingly among ethnically Chinese men. A Ministry of Primary Production statement that the vaccine is harmless to people seems only to give the rumour substance. Sufferers arrive at hospitals gripping themselves, or held by relatives, convinced they are dying.
- 3 NOVEMBER 1967 97 MEN ARE SEEN AT THE GENERAL HOSPITAL IN A SINGLE DAY, against a normal rate of about one case every two or three months. The later study records 469 cases in all, 95 per cent of them Chinese men. THE TRUE FIGURE IS HIGHER AND CANNOT BE RECOVERED: the count came mainly from hospital emergency units, and few doctors elsewhere sent returns.
- 4–7 NOVEMBER 1967 THE OUTBREAK IS ENDED BY PUBLIC STATEMENT. A Singapore Medical Association panel announces on 4 November, and the Ministry of Health on 6 November, also on television, that koro comes from fear and is not a physical disease with fatalities. Cases at the General Hospital fall to 38 the next day and to 17 on 7 November, and within a month there are none.
- 1982 A large koro epidemic runs through north-east India. Comparable genital-theft panics are documented in West Africa, where the attribution is to sorcery rather than to pork.
- 1994, then 2013 DSM-IV (1994) lists koro and amok in a glossary of CULTURE-BOUND SYNDROMES. DSM-5 (2013) drops the term for CULTURAL CONCEPTS OF DISTRESS, and koro is no longer on the list.
