One Health Practice by Harmonizing and Adopting the International Classification of Diseases-11

There are over 200 known zoonotic diseases. Over half of all recognized human pathogens are currently or originally zoonotic, as are 60%-76% of recent emerging pathogens, yet a few are coded in International Classification of Diseases-11 (ICD-11). The practice of animal health estimates is fragmented. The numbers and categorization of animals are not consistent across different organizations or over time. The coding attributes of ICD-11 on morbidity, mortality, and zoonoses don't exist in WAHIS. An innovation in methodology to adopt ICD-11 in World Animal Health Information System (WAHIS) and code for zoonoses is required. To meet the key principles of One Health High-Level Expert Panel (OHHLEP) and translate the One Health approach into actionable policies, there is a compelling need to estimate the magnitude of all human and animal diseases, particularly zoonoses, using the refined codes of ICD-11.
