Carrion's Disease: Symptoms and Treatment
Carrion's disease is endemic to certain regions of South America, particularly in Peru, Colombia, and Ecuador. The disease manifests in two distinct phases: an acute hematic phase known as Oroya fever and a chronic eruptive phase known as Verruga Peruana.
Phases of Carrion’s Disease
Carrion disease is the result of Bartonella bacilliformis, which evolves through two important stages: Oroya fever and Verruga Peruana. Symptoms are also very different at every stage and hence, they need to be treated differently per the stage to get them under control.
Oroya Fever (Acute Phase)
- This is the primary stage of Carrion's disease and is marked by acute febrile illness.
- Symptoms consist of acute anemia from the rupture of red blood cells, high fever, chills, headache and malaise.
- Untreated Oroya fever can become life threatening, though, with complications including organ failure. Timely diagnosis and treatment with antibiotics are important to the management of this stage.
Verruga Peruana (Chronic Phase)
- Verruga Peruana usually develops after Oroya fever and is characterised by the development of vascular lesions on the skin.
- These lesions, varying from small, wartlike growths to larger nodules, develop on the skin and are uncomfortable or bleed.
- Verruga Peruana, although not as deadly as Oroya fever, can greatly impair the quality of life.

Get Second OpinionCauses of Carrion's Disease
The primary cause of Carrion's Disease is infection by the Bartonella bacilliformis, which is transmitted to humans through the bite of infected sand flies, specifically the Lutzomyia species. The bacterium targets red blood cells, leading to a range of severe symptoms.
Carrion's Disease Symptoms
Understanding the symptoms of Carrion's disease is crucial for timely diagnosis and treatment.
Oroya Fever (Acute Phase)
Verruga Peruana (Chronic Phase)
- Cutaneous Lesions: Verruga Peruana is characterized by the appearance of wart-like nodules on the skin. These lesions can be mucosal, miliary, or nodular.
- Pain: The lesions can be painful and may lead to secondary infections.
- Bleeding: Some lesions might bleed, leading to further complications.
Carrion's Disease Diagnosis
Timely and accurate diagnosis is critical for effective treatment.
Laboratory Tests
- Blood Smear: Microscopic examination of blood smears can reveal Bartonella bacilliformis within red blood cells during the acute phase.
- Culture: Culturing the bacteria from blood samples, although time-consuming, is a definitive diagnostic method.
- Serological Tests: Detect antibodies against Bartonella bacilliformis.
Clinical Evaluation
- Medical History: A thorough medical history, including travel history to endemic areas, is vital.
- Physical Examination: Identifying characteristic symptoms and lesions.
Carrion's Disease Treatment
Timely medical intervention is essential for Treating Carrion's disease.
Antibiotic Therapy
- Chloramphenicol: Often used during the acute phase to target Bartonella bacilliformis.
- Ciprofloxacin: An alternative antibiotic, particularly useful in resistant cases.
- Rifampin: Used in combination with other antibiotics for enhanced effectiveness.
Supportive Care
- Blood Transfusions: For severe anemia.
- Fluid Replacement: To manage dehydration and maintain electrolyte balance.
- Pain Management: For symptomatic relief, particularly in the chronic phase.

Complications of Carrion's Disease
If left untreated, Carrion's disease can lead to severe and potentially life-threatening complications.
Acute Phase Complications
- Severe Anemia: Leading to hypoxia and organ failure.
- Secondary Infections: Due to weakened immune status.
- Heart Failure: As a result of severe anemia and hypoxia.
Chronic Phase Complications
- Chronic Skin Ulcers: Which may lead to secondary bacterial infections.
- Disfigurement: Due to extensive cutaneous lesions.
- Psychological Impact: From long-term skin manifestations and disfigurement.
How to Prevent Carrion's Disease
Carrion's disease Prevention measures focus on reducing exposure to the sand fly vector.
Vector Control
- Insect Repellents: Use of DEET-containing repellents to deter sand flies.
- Protective Clothing: Wearing long sleeves and pants.
- Bed Nets: Using insecticide-treated bed nets, especially in endemic regions.
Environmental Management
- Habitat Modification: Removing or treating breeding sites of sand flies.
- Community Education: Raising awareness about preventive measures.

What are the symptoms of Carrion's disease?
Carrion’s disease has two stages. In the acute phase (Oroya fever), signs and symptoms involve high fever, severe anemia, chills, and headache. In the chronic phase (Verruga Peruana), skin lesions resembling warts appear and may bleed or become painful.
What causes Carrion's disease?
Carrion's disease is caused by the bacterium Bartonella bacilliformis, which humans contract through the bite of infected Lutzomyia sandflies and most commonly occurs in tropical locations of South America.
How is Carrion's disease treated?
Antibiotics, such as ciprofloxacin or rifampin, are effective during both stages, thus making them useful in treating Carrion's disease. Acute phase within the early diagnosis and treatment to avoid the complications.
How can Carrion's disease be prevented?
Preventive measures include applying an insect repellent, and wearing protective clothing, and sleeping beneath mosquito nets in endemic zones. Because Carrion's disease is not endemic, there are currently no vaccines.
Can Carrion's disease cause complications?
Yes, Carrion's disease can cause serious complications if untreated, including organ failure in the acute phase (Oroya fever). In the chronic phase, untreated lesions can lead to secondary infections and long-term skin damage.
What are the clinical features of Carrion disease?
In the chronic phase, Carrion's disease is classically characterized by fever, anemia, myalgia, and the distinct skin lesions. Diagnosis typically includes blood tests to confirm Bartonella bacilliformis.
