How many animal diseases are included in the OIE single list?

The correct answer is 117, as this figure accurately reflects the current number of animal diseases included in the World Organisation for Animal Health’s (OIE) single list. The OIE single list consists of diseases that have significant economic, public health, and animal welfare impacts; these diseases are prioritized for surveillance and control measures on a global scale. The comprehensive inclusion of 117 diseases serves as a crucial framework for international cooperation and transparency in managing zoonotic risks and enhancing food security. Tracking these diseases is vital for maintaining animal health and preventing outbreaks that could affect human populations. This number changes as the OIE continually updates its criteria based on new scientific evidence and emerging threats, which underscores the dynamic nature of global health practices in relation to animal diseases.
