Introduction

Zoonotic diseases, which are transmitted from animals to humans, pose a significant threat to global health security. Emerging and re-emerging zoonoses, such as avian influenza, rabies, and West Nile virus, can cause severe illness, economic disruption, and social unrest. Effective prevention and control of these diseases require a multidisciplinary approach involving collaboration between human health, animal health, and environmental health professionals. This course provides participants with a comprehensive understanding of the epidemiology, transmission dynamics, and control strategies for zoonotic diseases. It emphasizes the importance of early detection, rapid response, and coordinated action to minimize the impact of zoonotic disease outbreaks. The course aims to build capacity among professionals working in public health, veterinary medicine, wildlife management, and related fields to effectively address the challenges posed by zoonotic diseases.
