Bartonellosis (Carrión´s disease, verruga peruana, Oroya fever, Guaitará fever) is caused by the Gram-negative bacillus Bartonella bacilliformis. It is endemic in the western Andes and inter-Andean valleys of Peru, and is still occasionally reported in Ecuador and Colombia, with infection resulting from the bite of various female sandflies. Infection of red blood cells manifests with non-specific ‘viral-type’ symptoms and haemolytic anaemia in the acute stage of disease. Following an asymptomatic phase, the late ‘eruptive’ stage is characterized by dermal nodules (‘verrugas’) that frequently heal spontaneously. Secondary opportunistic infections are common. Diagnosis in areas where the disease occurs is usually by demonstration of bacteria in the blood film. Mortality is 1.1–2.4% in endemic areas and around 9% in patients admitted to hospital. There is no satisfactory prevention for people living in endemic areas; tourists can take the usual precautions against being bitten by insects.
