Verruga peruana, also known as Peruvian wart, is a skin condition caused by the bacterium Bartonella bacilliformis. It is characterized by raised, wart-like lesions that typically appear on the skin, particularly in areas exposed to the sun. This condition is most commonly found in the Andean regions of Peru and can be associated with other symptoms, including fever and fatigue. The transmission of verruga peruana occurs through the bite of infected sandflies. The lesions can be painful and may take several weeks to heal. Treatment often involves antibiotics to address the underlying bacterial infection and alleviate symptoms.
