About CEAH

This report gives a comprehensive overview of CEAH's impact on safeguarding animal health in the United States for fiscal year 2022.


CEAH is located within APHIS Veterinary Services' (VS) Strategy and Policy (S&P) division. Our mission is to provide applied and innovative ​​​​​​​​​​​​analyses to generate science-based information and solutions for decision making around complex national animal health issues​.

We support key monitoring and surveillance programs across the United States and serve as the focal point for disease reporting to the World Organisation for Animal Health (WOAH). We are also a collaborating center for surveillance, risk assessment, and epidemiologic modeling with WOAH. In this role, we interact with collaborating centers domestically and internationally and participate in standards setting, analytical, and training activities.        

Staffed with a multidisciplinary team, CEAH provides scientifically sound and statistically valid information and tools to help policymakers reach critical decisions regarding animal health issues. Our team includes:

  • Epidemiologists and veterinarians
  • Spatial analysts and geographic information specialists
  • Economists and statisticians
  • Information and computer specialists
  • Biologists and entomologists
  • Librarians and technical writers
  • Administrative support

CEAH is made up of the following units:

  • National Animal Health Monitoring System (NAHMS)—NAHMS is the statistical unit within APHIS Veterinary Services responsible for population estimates related to animal health management and productivity. NAHMS conducts national studies on the health and health management of livestock, equine, aquaculture, and poultry populations within the United States at regular intervals.
  • Program Coordination and Implementation (PCI)—PCI strengthens CEAH’s mission by supporting staff with communications and editing support, project management, operations and logistics support, and Confidential Information Protection and Statistical Efficiency Act (CIPSEA) and Paperwork Reduction Act (PRA) compliance.
  • Geospatial Analytics, Products, and Services (GAPS)—GAPS provides map-centric products and solutions, as well as geospatial analyses that support emergency planning and response, disease risk analyses, epidemiology investigations, disease monitoring and reporting, and the overall mitigation and prevention of animal disease introduction and spread in the United States.
  • Surveillance Design and Analysis (SDA)—Through collaborative surveillance design, analysis, evaluation, and communication, SDA develops and enhances animal disease surveillance. SDA provides practical and timely surveillance solutions to meet customer needs, from single-premises sampling plans to robust national-level surveillance systems, including the proposed National List of Reportable Animal Diseases. SDA also serves as the WOAH Focal Point for U.S. animal disease reporting.
  • Transboundary Disease Analytics (TDA)—TDA identifies and characterizes global animal health hazards, assesses hazards and strategies to prevent the entry of transboundary diseases into the United States, conducts pathways assessments, and contributes to animal disease preparedness and response planning, implementation, and evaluations.
  • Domestic Animal Health Analytics (DAHA)—DAHA supports domestic disease programs through risk analysis, epidemiologic evaluations, and providing indemnity and compensation analyses and tools.
  • Animal health reporting
  • Antimicrobial resistance surveillance and monitoring
  • Comprehensive and integrated surveillance plans, evaluations, analytics, and reports
  • Data management, analytical support, and interactive visualization
  • Disease case definitions
  • Economic analysis
  • Emerging animal disease response, cost analysis, and support
  • Epidemiologic investigations and economic modeling
  • Foreign animal disease (FAD) deployment
  • Geospatial and mapping services
  • Indemnity estimates
  • Livestock-wildlife interface study/analysis
  • National and targeted animal studies
  • WOAH Collaborating Center activities
  • Ongoing animal health monitoring
  • Outbreak surveillance and epidemiologic support
  • Risk assessment and risk identification
  • Syndromic surveillance
  • Training and outreach

CEAH actively participates in various international and domestic scientific working groups, committees, and training. 

CEAH is a WOAH collaborating center for animal disease surveillance, risk analysis, and epidemiological modeling. We partner with WOAH and member countries to improve international disease surveillance capabilities and analytic methods supporting trade decisions through information sharing, risk identification, risk analyses, and surveillance activities.
