Global health crises refer to significant health challenges that affect populations across the world, often leading to widespread illness and mortality. These crises can arise from various factors, including infectious diseases like COVID-19, environmental changes, and social determinants of health. They require coordinated responses from governments, organizations, and communities to manage and mitigate their impact. During a global health crisis, healthcare systems may become overwhelmed, and resources can become scarce. Effective communication, public health measures, and international collaboration are essential to control the spread of diseases and protect vulnerable populations. Examples of past global health crises include the HIV/AIDS epidemic and the Ebola outbreak.
