Cat-transmitted sporotrichosis case definitions used in study of human cases in Curitiba, Brazil, 2011–2022*

Definition Epidemiology Clinical Laboratory
Proven
 History of trauma or contact with a cat with sporotrichosis
 Lesions compatible with sporotrichosis
 Positive culture and/or histopathology (microbiological evidence)
Probable
 History of trauma or contact with a cat with sporotrichosis
 Lesions compatible with sporotrichosis
 Human: Negative culture and/or histopathology.†
Sick cat: A) sporotrichosis diagnosed by culture and/or histopathology in a veterinarian laboratory; B) cat resident in a region with confirmed presence of cats with sporotrichosis (data verified by public health authorities)
Possible
 History of trauma or contact with a cat with sporotrichosis
 Lesions compatible with sporotrichosis
 Absent
Non-CTS History of trauma or contact with a cat with sporotrichosis Lesions compatible with sporotrichosis Negative culture and/or histopathology for Sporothrix spp.†
Definition of other case of disease (infectious or noninfectious)

*Adapted from Guide to Health Surveillance, 5th ed (23–25). CTS, cat-transmitted sporotrichosis. †Negative culture for Sporothrix spp. alone does not rule out diagnosis (limitation of the culture).
