In 2016, CIA officers in Havana, Cuba, began having unexplained well being points. They reported a persistent piercing sound adopted by signs together with complications, nausea, vertigo, hassle concentrating, and reminiscence loss. Was it a brand new situation? Or was it the newest incidence of the centuries-old phenomenon of mass psychogenic sickness, previously referred to as mass hysteria?

Since 2016, lots of of incidents of what’s now dubbed “Havana syndrome” have been recorded by U.S. intelligence and Overseas Service personnel in a rising listing of worldwide areas, together with Russia and China. As most have been working in hotbeds of espionage, surrounded by conventional U.S adversaries, many within the American authorities and media quickly started to suspect foul play.

Others are skeptical, theorizing that mass psychogenic sickness (MPI) is admittedly behind Havana syndrome. “Mass hysteria is an outbreak of a bodily sickness in a gaggle that seems to have an natural or physiological trigger, however really stems from psychological causes, usually from anxiousness,” says Gary Small, MD, professor of psychiatry at UCLA.

The query is way from settled. However MPI shouldn’t be a brand new phenomenon; examples pop up all through historical past. And whereas the signs, sufferers, and areas differ, some traits maintain regular: these sicknesses are sometimes born of stress, and so they unfold like wildfire amongst shut social networks. No two “epidemics” are precisely alike, however historical past might shed some gentle on the current murky scenario: If Havana syndrome is one other MPI, how does it examine to MPIs up to now? Can historic situations of mass psychogenic sickness contribute to a greater understanding of this elusive medical enigma?

MPI has been acknowledged for the reason that Center Ages. Dancing mania was first reported in Seventh-century Europe and reappeared throughout that continent till the seventeenth century, comprising big crowds dancing erratically for generally days at a time. A notable 1518 outbreak started with the feverish cavorting of a lone girl within the streets of Strasbourg in modern-day France. Theories as to why teams of as much as 400 folks adopted go well with embody stress-induced psychosis ensuing from widespread illness and famine within the area.

The notorious Salem, MA, witch trials of 1692-1693 have been a response to quite a few women having outlandish, inexplicable matches. The reason for these convulsions and their interpretation as proof of witchcraft are nonetheless debated. However collective rigidity ensuing from latest epidemics and posttraumatic stress dysfunction from the continued King William’s Battle, from which most of the affected women have been refugees, have been cited as components.

“You are inclined to see patterns,” says Small. “Individuals affected usually are in remoted conditions. There’s some type of stress that the group is experiencing with none technique of resolving it.”

The 1962 Tanganyika laughter epidemic started at a mission-run women’ boarding faculty in Kashasha, Tanzania. Beginning with three college students, matches of laughter lasting as much as a number of days unfold all through the varsity, forcing its closure. The epidemic then unfold to a village to which a number of college students had returned.

Small co-authored a study of a 1979 incident at a Boston elementary faculty when, whereas performing in an end-of-year play, an influential boy turned dizzy and fell, bleeding profusely. This triggered psychogenic responses together with dizziness, hyperventilation, and stomach ache in one-third of the coed physique.

“There are a selection of psychological stressors amongst these youngsters, not to mention simply the efficiency anxiousness they’re experiencing,” says Small, whose findings steered a relationship between childhood loss, reminiscent of parental divorce or household dying, and susceptibility to MPI.

In 1983, an outbreak of mass fainting and nausea affected 943 Palestinian women and some feminine Israeli troopers within the occupied West Financial institution. Israel and Palestine traded allegations of chemical warfare, however in the end a neighborhood well being official concluded that whereas the primary 20% of circumstances have been in all probability brought on by an unidentified fuel, the rest have been primarily psychosomatic, in keeping with Time journal.

A UCLA investigation of a 1989 incident by which 247 scholar performers, most of them feminine, turned violently sick at Santa Monica Civic Auditorium equally famous that youngsters who noticed a good friend turn into sick have been the most certainly to develop signs, which have been thus transmitted via social networks.

A whole bunch of women at a boarding faculty close to Mexico Metropolis skilled unexplained leg ache, nausea, and fever throughout 2006-2007. It was a closed neighborhood, with college students denied entry to tv or radio. The ensuing nearly familial bonds between them might have contributed to what psychiatrist Nashyiela Loa Zavala, who investigated the case, has termed the “audiovisual contagion” of MPI.

Commonalities exist between a minimum of some Havana syndrome circumstances and historic MPI outbreaks. MPI normally begins amongst a small, cohesive group of individuals of upper standing, in a disturbing scenario, after which spreads.

“The involvement of 4 [CIA agents] from the identical station is a defining characteristic of mass psychogenic sickness, which is understood to observe social networks,” says New Zealand-based medical sociologist Robert Bartholomew, PhD.

Most Havana syndrome circumstances are personnel remoted removed from residence in abroad embassies, not in contrast to the boarding college students concerned in lots of MPI outbreaks. They’re bonded by a disturbing work atmosphere, beneath fixed surveillance, and certain cognizant of Russia’s alleged prior use of microwave transmissions to disrupt U.S. intelligence. But for causes of nationwide safety, they’re sometimes unable to share associated anxieties with household or “civilian” mates.

Some signs beforehand attributed to MPI, together with headache, dizziness, and nausea, have been related to Havana syndrome. Bartholomew steered that “reframing” of those widespread complaints by these affected, to mirror what medical doctors and authorities authorities are telling them, might contribute to the phenomenon. In different phrases, folks is perhaps experiencing generic signs widespread in MPI and be inclined to sinister explanations — with none proof for them.

Havana syndrome outbreaks are separated by generally 1000’s of miles, which ostensibly eliminates audiovisual contagion. However the web has redefined the idea of “neighborhood” to now transcend geographical proximity. Social media and on-line information undoubtedly made U.S. diplomats and intelligence officers properly conscious of graphic descriptions of Havana syndrome signs from friends all over the world, a few of whom can be personally identified to them from prior postings.

Nevertheless, Havana syndrome doesn’t meet all widespread MPI standards. Small famous “a preponderance of signs [of MPI] in women or ladies in contrast with boys or males.” Certainly, MPI disproportionately impacts young girls greater than another demographic. But nearly all of Havana syndrome circumstances have been middle-aged males.

There isn’t a consensus on the reason for Havana syndrome. Theories vary from the mating name of crickets to a sonic weapon. Some specialists keep that early circumstances of Havana syndrome current unambiguous proof of neurological injury in keeping with publicity to microwave radiation. But they continue to be open to contributing psychosocial components in a minimum of some situations.

“We discovered [microwave radiation] to be most believable in explaining a subset of the circumstances, not all circumstances,” says David Relman, MD, a Stanford College microbiologist who headed the Nationwide Academy of Sciences Research of Havana syndrome. Relman stated that this subset comprised employees of the American embassy in Cuba and on the U.S. consulate in Guangzhou, China, which was the second location to report signs.

James Giordano, PhD, professor of neurology at Georgetown College and advisor to the Pentagon, stated that the unique circumstances on the Havana embassy “had goal options — clinically relatable, objectifiable, and legitimate and evidentiary indicators — that have been indicative of some type of neurological trauma or insult.” However he famous that solely a fraction of the worldwide incidents up to now have been verified as assembly the complete, goal medical standards for the kind of anomalous well being incident referred to as Havana syndrome.

After 5 years, lots of of circumstances on a number of continents, and steady, inconclusive investigation, there might by no means be a definitive reply as to if Havana syndrome is bodily or psychogenic. However historical past might deliver extra readability than Chilly-Battle-era spycraft. Havana syndrome has some main variations from MPI epidemics of the previous, however in some ways it’s extra comparable than not — and paranoia within the American intelligence neighborhood would hardly be unprecedented.
