title: [Tungiasis in native Amerindians in Vaupés province: epidemiology, clinical aspects, treatment, and prevention].
abstract: BACKGROUND
  Tungiasis, the skin infestation with the flea Tunga penetrans, occurs in poor communities. Objective. To present a study of this condition among native Amerindians from Vaupés (Colombia).
  
  
  METHODS
  After reviewing this topic, we present a description of the geographic area and the housing of the affected subjects; animal carriers infected with this zoonosis were also detected. We illustrate the clinical aspects and complications. Patients were treated with creolin (liquid cresol). We modified the floor of malocas in two communities using wet clay, and we educated the community on this parasite.
  
  
  RESULTS
  About 95% of the 33,000 inhabitants of Vaupés are native Amerindians. Some households have dry sandy floors, where food leftovers attract dogs infested with tungiasis. From 1996 to 2007 we confirmed 942 human cases of this parasitic disease. Among the native communities, 3 to 8 per 1,000 persons and 62% of the dogs have tungiasis. Feet were affected in 98% of the patients. Severe cases, with more than 20 lesions, occurred among children and the elderly. Complications included secondary infections, pain, anonychia (loss of toenails), toe deformities, amputation of toes and walking problems. Three patients died as a result of sepsis originating from toe infections. Topic use of liquid creolin and extraction of the parasite cured the problem in humans and dogs. Floor modifications eradicated the problem in one community.
  
  
  CONCLUSIONS
  Tungiasis is an intradomiciliary disease. Favorable conditions for infestations include dry sandy floors and infected dogs. Treatment of the floors with creolin and wet clay resulted in control of one focus of the disease; this method could be applied more widely. This is the first known research study on tungiasis in Colombia, a disease that affected the soldiers of the Spanish Conquistador Gonzalo Jiménez de Quesada in the 1500s.
