The National Center for Emerging and Zoonotic Infectious Disease at the Centers for Disease Control and Prevention published 2011 data on 6,037 cases of confirmed animal rabies in 49 states and Puerto Rico. Hawaii is a rabies-free state. Of these rabies cases, 92% were confirmed in wildlife and 8% in domestic species. These do not represent all rabies cases in the United States since rabies cases, especially in wildlife, go unobserved and undetected.

Eleven states and Puerto Rico reported 44 rabid equids in 2011: Florida (1), Georgia (1), Kentucky (1), Maine (1), Nebraska (4), New Jersey (1), North Carolina (3), Oklahoma (1), Puerto Rico (4), South Dakota (1), Tennessee (2), Texas (22), and Virginia (2).

Canada reported two cases in equids, and Mexico reported three rabid horses.

Rabies is a viral disease that is a reportable disease in the United States for humans and animals
