title: [The complex plague--reconsiderations of an epidemic from the past].
abstract: Speculations have arisen about the black plague in recent years - was it a disease caused by YERSINIA PESTIS: or something else? Extensive outbreaks in India in the 1890s have formed the basis for descriptions of the plague, both for those who believe that the medieval plagues and modern plague were different diseases and for those who claim that the plague has been one and the same disease throughout history. The plague was more or less defined as a disease in the 1890s, and the understanding of its clinical course and dissemination at the time has uncritically been understood as the general model for spreading of the plague. But plague is a many-faceted disease. It has spread to five continents in modern times, through an array of ecosystems and under widely different climatic conditions. It can also be passed on to man, and from one individual to another, in different ways. The biological conditions that prevailed in India have not been relevant for medieval Norway. The preconditions for spreading of plague epidemics of the past in a Nordic climate must therefore have been different. It can only be expected that contemporary descriptions of historic epidemics are different from those in modern times.
