(Synonyms: Peruvian Warts; Carrion's Disease; Oroya Fever.)

Describe verruga peruana.

A specific inoculable affection endemic in some valleys of the Western Andes, in Peru, and characterized by a prodromal febrile period and subsequent outbreak of peculiar pin-head- to pea-sized, or larger, bright reddish, rounded, wart-like elevations. The prodromal symptoms, of an irregular malarial or typhoid type, with associated rheumatic and muscular pains, may last for weeks or several months, usually abating when eruption presents. The lesions may be crowded together in great bunches. The face and limbs are favorite localities. The disease is inoculable and thought to be due to a bacillus.

The fatality varies between 10 and 20 per cent. Tonics and stimulants are prescribed.
