Emergence of Feline Sporotrichosis near Brazil Border, Argentina, 2023-2024

Emerg Infect Dis. 2025 May;31(5):1045-1048. doi: 10.3201/eid3105.241882.

Abstract

We describe a large urban outbreak of feline sporotrichosis caused by Sporothrix brasiliensis fungi in Argentina. Over a 7-month period in Puerto Iguazú, which borders Brazil, we identified culture-proven sporotrichosis in 9 cases across 7 households. Public health officials should coordinate cross-border One Health actions and institute context-specific interventions.

Keywords: Argentina; One Health; cats; communicable diseases; emerging; fungi; sporotrichosis; zoonoses.
