Top 5 Bizarre Cases of Mass Hysteria

5. Mumbai Sweet Water

The 2006 Mumbai “sweet” seawater incident was a phenomenon during which residents of Mumbai claimed that the water at Mahim Creek, one of the most polluted creeks in India that receives thousands of tonnes of raw sewage and industrial waste every day, had suddenly turned “sweet”. Within hours, residents of Gujarat claimed that seawater at Teethal beach had turned sweet as well. In the aftermath of the incidents, local authorities feared the possibility of a severe outbreak of water-borne diseases, such as gastroenteritis. The Maharashtra Pollution Control Board had warned people not to drink the water, but despite this many people had collected it in bottles, even as plastic and rubbish had drifted by on the current. By 2pm the following day, the devotees said that the water was salty again.

4. Tanganyika laughter epidemic

The Tanganyika laughter epidemic of 1962 was an outbreak of mass hysteria, believed to have occurred in or near the village of Kashasha on the western coast of Lake Victoria in the modern nation of Tanzania near the border of Kenya. It is possible that, at the start of the incident, a joke was told in a boarding school, and that this joke triggered a small group of students to start laughing. The laughter perpetuated itself, far transcending its original cause. The school from which the epidemic sprang was shut down; the children and parents transmitted it to the surrounding area. Other schools, Kashasha itself, and another village, comprising thousands of people, were all affected to some degree. Six to eighteen months after it started, the phenomenon died off. The following symptoms were reported on an equally massive scale as the reports of the laughter itself: pain, fainting, respiratory problems, rashes, and attacks of crying.
3. June Bug Epidemic

In 1962 a mysterious disease broke out in a dressmaking department of a US textile factory. The symptoms included numbness, nausea, dizziness, and vomiting. Word of a bug in the factory that would bite its victims and develop the above symptoms quickly spread. Soon sixty two employees developed this mysterious illness, some of whom were hospitalized. The news media reported on the case. After research by company physicians and experts from the US Public Health Service Communicable Disease Center, it was concluded that the case was one of mass hysteria. While the researchers believed some workers were bitten by the bug, anxiety was likely the cause of the symptoms. No evidence was ever found for a bug which could cause the above flu-like symptoms, nor did all workers demonstrate bites.
2. Soap Opera Hysteria

Morangos com Açúcar is a Portuguese youth soap opera, which is very popular in Portuguese communities, especially amongst children and teenagers, aiming to depict the adventures of typical Portuguese youths. In May, 2006, an outbreak of the “Morangos com Açúcar Virus” was reported in Portuguese schools. 300 or more students at 14 schools reported similar symptoms to those experienced by the characters in a recent episode. These included rashes, difficulty breathing, and dizziness, forcing some schools to close. The Portuguese National Institute for Medical Emergency dismissed the illness as mass hysteria. This story concerned some parents because of the major influence this series has on the kids and teens that watch, it was in newspaper and magazines articles and elsewhere.
1. The Toxic Lady

Gloria Ramirez was a Riverside, California, woman dubbed “the toxic lady” by the media after exposure to her body and blood had sickened several hospital workers. She was rushed to hospital in 1994 suffering from the effects of cervical cancer. The medical staff who attended to her all began to feel ill and eventually fainted. Gloria’s body exuded a garlicky and fruity smell and her blood contained flecks of a strange substance like paper. The odd thing about this case is that of those who handled Gloria’s body or treated her, more women than men suffered from the ill-effects and everyone involved had normal results in blood tests. The health department issued a statement at the conclusion of their investigation which said that those who had become sick were, in fact, suffering from mass hysteria.
