My principal object in a recent visit to Peru was to obtain first hand information of the cutaneous lesions of the disease known in that country as verruga peruana. To understand fully its eruptive phase it is necessary to give a general description of this fascinating and unique disease.
Before the causative organism was successfully cultivated, there was some doubt about the relationship of what was called Oroya fever and the cutaneous eruption known as verruga. As it has now been proved beyond any possibility of doubt that these two supposedly different disorders are in reality the same disease, it is perhaps best to characterize the entire process as Carrion's disease, in honor of the young student who lost his life after a voluntary inoculation.
HISTORY OF THE DISEASE
Carrion's disease probably existed in remote times and is generally thought to have been known to the Spanish conquerors of Peru.
