The International Health Regulations (IHR) established in 2005 aim to improve the global response to public health emergencies by requiring countries to detect, assess, report, and respond to potential threats. As a legally binding agreement among 196 nations, the IHR emphasizes the importance of international cooperation and the necessity of a coordinated response to health threats, despite challenges posed by national sovereignty and resource limitations. The emergence of infectious diseases like hemorrhagic fever highlights the critical need for effective implementation of IHR to ensure global health security and timely public health interventions.
