Abstract
Zoonotic transmission of Cryptosporidium parvum (C. parvum) is often associated with ruminants. We report an investigation of cryptosporidiosis among persons who had contact with raccoons. In July 2024, two states identified 18 human cryptosporidiosis cases who volunteered at the same animal facility. One human specimen and two raccoon specimens tested positive for C. parvum. Molecular subtyping of the C. parvum (subtype IIaA15G2R1) suggested zoonotic transmission between raccoons, humans, or their shared environments. These findings can inform public health actions, developed in collaboration with specific populations (e.g., wildlife rehabilitation facilities) and include interventions tailored to such settings to mitigate future outbreaks.
