Voluntary 2024 U.S. National Animal Health Reporting System (NAHRS) 

Reportable Diseases, Infections, and Infestations List

Changes from previous year:1

Leishmania and Trypanosomosis (tsetse-transmitted) (Trypanosoma congolense, T. vivax, T. brucei, T.

simiae) were moved under multispecies. Low pathogenic avian influenza (LPAI) has been updated to

include reporting of subtypes associated with human illness. Bovine tuberculosis (Mycobacterium bovis) 

was incorporated under Mycobacterium Tuberculosis Complex. B. divergens was incorporated under 

Bovine babesiosis. The following were added as notifiable: Infection with Theileria lestoquardi, T. 

luwenshuni and T. uilenbergi; Infection with Enterocytozoon hepatopenaei; Infection with Marteilioides 

chungmuensis; and Infection with Ostreid herpsesvirus-1. The following were added as monitored: 

Infection with Haplosporidian nelsoni (Hp) and infection with Mikrocytos mackini. The following were 

moved from notifiable to monitored: Epizootic ulcerative syndrome (EUS) (Infection with Aphanomyces

invadans); Infection with Ranavirus (Ranavirus species); and Infection with Batrachochytrium 

dendrobatidis. 

Definitions:

Notifiable Diseases

• Notifiable diseases and conditions consist of emergency incidents, emerging disease incidents, and 

regulated disease incidents. Immediate reporting by Animal Health Professionals.

Monitored Diseases

• Monitored diseases are those that are endemic in the United States. Monthly reporting by State Animal

Health Officials and Laboratories. Animal and Plant Health Inspection Service (APHIS) uses data 

gathered to monitor changes in disease occurrence over time.

Terrestrial

• Animals that live predominantly or entirely on land.

Aquatic

• Animals which live predominantly or entirely in the water.

Animal Health Professional

• An Animal Health Professional is an individual, corporate entity, or animal health organization with 

formal training in the diagnosis or recognition of animal diseases and/or pests of livestock. Examples of 

animal health professionals include, but are not limited to, veterinary medical professionals, diagnostic 

laboratorians, biomedical researchers, public health officials, animal health officials, trained 

technicians, zoo personnel, and wildlife personnel with such training.
