Reliable supply chains are critical to uninterrupted health services. When procurement systems falter or logistics break down, whether due to natural disasters, pandemics, or geopolitical tensions, essential medicines, diagnostics, and equipment can vanish from facilities. Such stock-outs delay treatments, jeopardize patient safety, and force providers to ration or substitute critical items. Without supply-chain resilience, front-line health workers cannot respond effectively to surges in demand, leading to preventable morbidity and mortality. Robust logistics thus underpin both routine care continuity and rapid crisis response, ensuring that no interruption in supplies undermines system stability or public trust.
