The National Animal Health Reporting System (NAHRS) is the only comprehensive reporting system for World Organization for Animal Health (OIE)-reportable diseases in the United States. Under NAHRS, participating State animal health officials report monthly on the occurrence of confirmed OIE-reportable diseases and other diseases of interest occurring in U.S. livestock, poultry, and aquaculture species. NAHRS is an important component of comprehensive and integrated surveillance in the United States. By providing timely summary-level information on animal health status to our trading partners, NAHRS helps protect the U.S. share of the global market for animals and animal products.
