Reporting Guidelines 

Q1: How can I access a 

downloadable list of NLRAD 

reportable diseases and case 

definitions? 

The National List of Reportable Animal Diseases is available on 

the NLRAD website. Most NLRAD Case Definitions (CDs) are 

currently under review; once cleared for posting, CDs will be 

available on the NLRAD website. The World Organisation for 

Animal Health (WOAH, formerly OIE) Terrestrial and Aquatic 

diagnostic manuals also provide detailed information on listed 

diseases. 

Q2: What are the guidelines for NLRAD disease specific Case Definitions (CDs) provide a 

reporting diseases under NLRAD? general disease overview, laboratory criteria, case classification 

details and reporting criteria. Available CDs are on the NLRAD 

website (see FAQ 1 above). Cases should be reported to NLRAD 

in accordance with the NLRAD Standards. 

Q3: Where can I find case Case Definitions (CDs) are currently being reviewed and NLRAD Website 

definitions for NLRAD diseases? updated. Available CDs are on the NLRAD website (see FAQ 1 

above). More will be added to this site as they are reviewed and 

finalized. You can also reference the WOAH (OIE) Terrestrial and 

Aquatic diagnostic manuals for detailed information on listed 

diseases. 

Please contact the NLRAD Team (NLRAD.NAHRS@usda.gov), if 

you have specific questions about a listed disease that we can 

help clarify.

Q4: What are the reporting Please report Notifiable diseases/conditions within 24 hours 

timeframes for NLRAD Notifiable according to the NLRAD Standards. 

and Monitored diseases? 

Please report Monitored diseases/conditions within 30 days 

according to the NLRAD Standards. 

Q5: Who is an “Animal Health 

Professional”? 

An Animal Health Professional (AHP) 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. 

Q6: What are the NLRAD reporting 

requirements for state animal 

health officials? 

State Animal Health Officials (SAHOs) should report cases of 

NLRAD listed diseases in accordance with the NLRAD 

Standards. Available CDs are on the NLRAD website (see FAQ 1 

above). 

Q7: What are the NLRAD reporting All Animal Health Professionals, including laboratory personnel, 

requirements for laboratories? should coordinate with their state animal health official and Area 

Veterinarian in Charge (AVIC) to ensure confirmed cases of 

NLRAD listed diseases are reported in accordance with the 

NLRAD Standards. Available CDs are on the NLRAD website 

(see FAQ 1 above). 

Please report Notifiable diseases/conditions within 24 hours. 

Please report Monitored diseases/conditions within 30 days. 

IMPORTANT NOTE: Reporting under NLRAD does not 

supersede State requirements or notification processes for FADEmerging Diseases Incidents or other Regulated/High Priority 

Endemic Disease reporting requirements. 
 

 

 

Q8: What are the NLRAD reporting 

requirements for other Animal 

Health Professionals? 

All Animal Health Professionals, including accredited 

veterinarians, should coordinate with their state animal health 

official and Area Veterinarian in Charge (AVIC) to ensure 

confirmed cases of NLRAD listed diseases are reported in 

accordance with the NLRAD Standards. Available CDs are on 

the NLRAD website (see FAQ 1 above). 

Please report Notifiable diseases/conditions within 24 hours. 

IMPORTANT NOTE: Reporting under NLRAD does not 

supersede State requirements or notification processes for FADEmerging Disease Incidents or other Regulated/High Priority 

Endemic Disease reporting requirements. 

Q9: For non-negative laboratory 

results, where can I find diseasespecific reporting requirements 

under NLRAD? 

Refer to NLRAD disease specific CDs, which include laboratory 

criteria, case classification details and reporting criteria. Available 

CDs are on the NLRAD website (see FAQ 1 above). 

If no NLRAD case definition is available, see laboratory and 

reporting criteria in disease specific WOAH guidance. 

Cases should be reported to NLRAD in accordance with the 

NLRAD Standards. 

Q10: Should Monitored diseases 

that are not confirmed be 

reported? 

If you have a presumptive or suspect case of a Monitored 

disease that does not meet the confirmed case definition, you 

may consider other information, such as alternative laboratory 

testing or additional epidemiological information, to decide 

whether to report the presence of the disease. The NLRAD Team 

recognizes that for many Monitored diseases, especially endemic 

diseases, Animal Health Professionals may not have diagnostic 

testing results to a confirmed case level. 

Q11: Are NLRAD disease 

detections in wildlife reportable? 

Yes. 
 

 

 

 

The focus of NLRAD is on disease occurrences in livestock, 

poultry, and aquaculture. Officials may report NLRAD disease 

information in wildlife or feral species and are encouraged to do 

so. However, Reporting Officials should clearly note in the 

comments section of the NLRAD-NAHRS Report when a disease 

detection is related to wildlife or feral species. 

Q12: What is difference between 

the NAHRS list and the NLRAD 

list? 

There is no difference between the diseases listed on the NLRAD 

list and the diseases listed in the National Animal Health 

Reporting System (NAHRS). The NAHRS website is updated 

each year to ensure it provides State Animal Health 

Professionals (SAHOs) the opportunity to report on all current 

NLRAD listed diseases. 

Emerging Disease 

Q1: What diseases/conditions are 

considered “Emerging” under 

NLRAD? 

The NLRAD Standards defines an emerging disease as a 

disease, infection, or infestation in domestic or wild animals that 

is a threat to terrestrial animals, aquatic animals, or humans, and 

meets one of the following criteria: 

• An unknown agent that is causing disease in a 

herd/flock/premises and has the potential to result in a 

significant animal or public health impact, and applied 

diagnostic tests have yielded negative or non-definitive 

results; OR 

• A newly identified agent that is causing disease in a 

herd/flock/premises and has the potential to cause 

significant animal or public health impact, or is occurring 

in multiple herds/flocks/premises; OR 

• A previously identified or known pathogenic agent that 

has a change in epidemiology, such as: 

• Unexpected production impacts or 

morbidity/mortality over a previously defined range 

for the agent 

• Expanded host range 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Change in geography of an agent with the potential to

cause a significant animal or public health impact

Q2: How should Emerging If you suspect an emerging animal disease, follow the notification 

Diseases/Conditions be reported? process in the policy for the Investigation of Potential Foreign 

Animal Disease/Emerging Disease Incidents (FAD/EID). 

When an emerging disease is confirmed, APHIS will decide 

specific details of how and what to report to WOAH on a case-bycase basis. Report to NLRAD within 24 hours of confirmation.
