Factors which have been identified as impeding the identification of pathogens include the following: 1. Lack of animal models: Experimental infection in animals has been used as a criterion to demonstrate a disease-causing ability, but for some pathogens (such as Vibrio cholerae, which causes disease only in humans), animal models do not exist.
The disease typically lasted through one full day before recovery or death took place. [3] The disease tended to occur in summer and early autumn. Thomas Forestier, a physician during the first outbreak, provided a written account of his own experiences with the sweating sickness in 1485. [ 4 ]
