The epidemic subsided in Central Europe in the seventeenth century, but diseases approximating to the original dancing mania have occurred at various periods in many parts of Europe, Africa, and the United States. Nathaniel Pearce, an eye-witness, who resided nine years in Abyssinia early in the nineteenth century, gives a graphic account of a similar epidemic there, called _tigretier_, from the Tigre district, in which it was most prevalent. In France, from 1727 to 1790, an epidemic prevailed among the Convulsionnaires, who received relief from brethren in the faith known as Secourists, very much after the rough methods administered to the St. John's dancers and to the _tarantati_. About the same period nervous epidemics of a similar character, largely propagated by sympathy, were very prevalent in the Shetland Islands and in various parts of Scotland, but were for the most part eradicated by cold-water immersion. An epidemic of _chorea sancti Viti_, recorded by Felix Robertson of Tennessee (Philadelphia, 1805), found vent in an unparalleled blaze of enthusiastic religion, which spread with lightning-like rapidity in almost every part of Tennessee and Kentucky, and in various parts of Virginia, in 1800, being distinguished by uncontrollable and infectious muscular contractions, gesticulations, crying, laughing, shouting, and singing. To similar epidemics are attributed the uncontrollable acts which, till late in the nineteenth century, were a feature of North American camp meetings for divine service in the open air, and which exhibited the same form of mental disturbance as did the St. Vitus' dance in mediaeval Europe.
