Bartonelosis (Carrion's Disease) in the pediatric population of Peru: an overview and update.

Bartonellosis, or Carrion's Disease, is an endemic and reemerging disease in Peru and Ecuador. Carrion's Disease constitutes a health problem in Peru because its epidemiology has been changing, and it is affecting new areas between the highland and the jungle. During the latest outbreaks, and previously in endemic areas, the pediatric population has been the most commonly affected.
