Which instrument is central to international health law and governs responses to health threats?

• A. International Health Regulations
• B. Paris Agreement
• C. Basel Convention
• D. Montreal Protocol

Answer: (A)

The main idea here is how international rules coordinate health security across borders. The instrument that governs responses to health threats on a global scale is the International Health Regulations. These regulations, binding on WHO member states, establish a framework for detecting, reporting, and responding to public health risks that could cross borders. They require countries to develop core surveillance and response capacities, assess and notify potential public health emergencies of international concern, and coordinate actions while minimizing unnecessary disruption to travel and trade. This combination of surveillance, notification, and coordinated response is what makes the International Health Regulations the central tool of international health law.

The other instruments address different global issues. The Paris Agreement focuses on climate change, the Basel Convention on hazardous waste management, and the Montreal Protocol on ozone-depleting substances. While each has public health implications, none provides the structured, legally binding framework specifically for outbreak detection, reporting, and international response that international health law relies on.
