South American bartonellosis
The primary infection, transmitted by the sandfly bite, results in febrile hemolytic anemia and is referred to as Oroyo fever. The subsequent disease results in eruption of chronic cutaneous angiomatosis and is referred to as verruga peruana. The initial phase may last from 1-6 weeks, and the second verrucous phase begins 2-20 weeks after recovery from the fever.
There is no race, age, or sex predilection. Since the initial description of bartonellosis, 13 other species have been added to the family Bartonellaceae that cause other diseases including cat-scratch disease and trench fever. Bartonellosis usually refers to infection with B bacilliformis, but other species are being identified.
