👉 The term "infection" within the context of international law, particularly as it pertains to treaties, generally refers to the spread of disease or harmful microorganisms from one person to another, often facilitated by human activities. In the framework of international health treaties, such as the International Health Regulations (IHR) 2005, infection is defined and regulated to prevent the international spread of diseases that could pose a significant public health threat. These regulations require states to implement measures to detect, report, and respond to infectious disease outbreaks, ensuring global health security. The treaty emphasizes cooperation among nations to share information, resources, and best practices in managing infectious diseases, aiming to protect populations while minimizing economic and social disruptions.
