The American Animal Hospital Association has issued new 2026 One Health Guidelines to address the rising threat of 21 emerging parasites in dogs and cats. These protocols provide veterinarians with standardized approaches for diagnosing and treating infections that can impact both pet and human health.
Why it matters
Parasites are becoming more prevalent due to factors like environmental shifts and antiparasitic resistance, making updated clinical standards essential for protecting household pets. This guidance helps veterinary teams manage emerging risks more effectively through improved diagnostic and communication protocols.
The new 2026 One Health Guidelines provide clinical direction for 12 emerging parasites of high concern and 9 additional parasites of potential concern. These figures represent an updated framework compared to previous standards for pet parasite management in the United States.
