What type of diseases does the OIE primarily deal with?

The correct answer is focused on animal diseases that can have a significant impact on international trade. The World Organisation for Animal Health (OIE) concentrates on ensuring the control and prevention of infectious diseases in animals, which is crucial for safeguarding both animal health and the economy associated with livestock and animal products. By addressing animal diseases, the OIE aims to prevent outbreaks that could disrupt trade and pose risks to food security.

This emphasis on animal diseases that affect international trade is vital because many countries rely heavily on agricultural exports, and any disease outbreak can lead to trade restrictions and economic losses. The OIE creates guidelines and standards to facilitate safe international trade while minimizing risks associated with the transmission of animal diseases.

In contrast, human infectious diseases are typically managed by different organizations, such as the World Health Organization (WHO). Plant diseases are of concern but fall under the purview of organizations that specialize in agricultural health and trade, rather than the OIE's primary objectives related to animal health. Therefore, the focus on animal diseases that affect trade distinguishes the OIE's mission from those of other health organizations.
