"The symptoms experienced are real - fainting, palpitations, headaches, nausea, shaking and even fits," he says. "It is often attributed to a medical condition but for which no conventional biomedical explanation can be found."
Transmission, he adds, "is largely due to psychological and social factors".
Outbreaks have been recorded around the world, with cases dating back as early as the Middle Ages. Incidents in Malaysia were particularly prevalent among factory workers during the 1960s. Today it largely affects children in schools and dormitories.
