Quick Summary

Verruga peruana is a clinical stage of Carrión disease, a rickettsial infection endemic to South America. This disease is caused by the bacterium Bartonella bacilliformis and is transmitted by sand flies in the Andes Mountains.1

Carrión disease has two phases:
* Oroya fever: An acute, febrile anemia that can be fatal if untreated.1
* Verruga peruana: A more benign skin eruption characterized by reddish papules and nodules. This phase typically appears after Oroya fever or in individuals who haven't had the acute phase, and it is thought to indicate developing immunity.1

Diagnosis involves blood tests and antibody detection, and the disease responds well to antibiotics. Control focuses on eliminating the insect carrier through insecticides.1
