<h3>Today, mass psychogenic illness normally develops through the fear of a viral outbreak and other biological factors.</h3>
Explanation:
Unlike the past, today mass psychogenic illness does not develop through customs or ritualized behaviors. The "Dancing Manias" of the Middle Ages was believed to have caused due to religious beliefs like a curse sent by a godly entity or a punishment from the God.

Mass hysteria of being contracted with a certain disease or illness is mostly believed by the victims. They do not trace their illness to any supernatural elements but rather believes it as something man-made or a viral outbreak.
