Ringworm Roundup 2: Outbreak Management
In the second half of “Ringworm Roundup,” Dr. Sandra Newbury, National Shelter Medicine Extension Veterinarian for the UC Davis Koret Shelter Medicine Program, discusses a step-by-step plan for managing any disease outbreak, but with a specific focus on ringworm. Learn how to stop the spread of disease and implement a proactive approach to keep ringworm from breaking out in your animal population again. This presentation is part of the University of Florida's Maddie's Shelter Medicine Program track at the 2013 No More Homeless Pets National Conference.

What are the three categories and associated locations that animals are split into based on the evaluation of clinical signs (including a Wood’s lamp evaluation)?
- A.
Positive animals are removed from the general population; suspect (lesional) animals are isolated/separated; non-lesional and Wood’s lamp negative animals’ intervention is based on clinical assessment.
- B.
Positive animals are reintroduced into the general population; suspect (lesional) animals are isolated/separated; non-lesional and Wood’s lamp negative animals’ intervention is based on clinical assessment.
- C.
Positive animals are removed from the general population; suspect (lesional) animals are transferred to adoption; non-lesional and Wood’s lamp negative animals’ intervention is based on clinical assessment.
- D.
Positive animals are removed from the general population; suspect (lesional) animals are isolated/separated; non-lesional and Wood’s lamp negative animals are quarantined while waiting for fungal culture results.
- E.
Positive animals are removed from the general population; suspect (lesional) animals are kept in separate cages but remain with the general population; non-lesional and Wood’s lamp negative animals’ intervention is based on clinical assessment.

An identification/diagnosis of the primary agent, an assessment of the capacity to respond and an assessment of the impact of not responding.
