Who sets the internationally recognized reportable disease lists?

The correct answer is the World Health Organization (WHO), which is responsible for establishing the internationally recognized reportable disease lists. This organization plays a crucial role in public health by coordinating global responses to health emergencies and ensuring that diseases with epidemic potential are monitored and reported by countries around the world. The WHO updates and maintains the International Health Regulations (IHR) that specify the diseases considered to be of international concern, requiring countries to report cases and outbreaks.

While other organizations like the United Nations and the Centers for Disease Control and Prevention (CDC) contribute to global health efforts and disease surveillance in their respective ways, they do not set the international standards for disease reporting. The World Animal Health Organization (OIE) primarily focuses on animal health and zoonotic diseases but is not responsible for the overall international list of reportable diseases that fall under human public health as governed by WHO.
