From National Headlines to Local Exam Rooms: What's Creeping into Companion Animal Practice

Course overview

Emerging and re-emerging parasitic diseases are increasingly capturing national attention, but their impact extends far beyond the headlines and into everyday companion animal practice. Changes in climate, wildlife ecology, animal movement, and global commerce are reshaping parasite distribution patterns, exposing pets and their owners to risks that may not have historically existed in their region. This presentation explores the factors driving parasite emergence and examines several important threats currently affecting veterinary medicine, including the Asian longhorned tick (Haemaphysalis longicornis), New World screwworm (Cochliomyia hominivorax), and Echinococcus multilocularis. Participants will review current epidemiologic trends, clinical implications, public health considerations, and practical approaches for identifying and managing these emerging risks. The session will also highlight the veterinarian's role in surveillance, prevention, client communication, and One Health initiatives that support animal and human health. Through an evidence-based review of emerging parasite threats, attendees will gain actionable strategies for incorporating risk assessment, prevention, and education into daily clinical practice.
