A global health crisis refers to a significant health challenge that affects populations across multiple countries or continents. These crises can arise from various factors, including infectious diseases, environmental changes, or health system failures. Examples include the COVID-19 pandemic, which spread rapidly worldwide, and the Ebola outbreak in West Africa. During a global health crisis, healthcare systems may become overwhelmed, leading to increased morbidity and mortality rates. Governments and organizations, such as the World Health Organization (WHO), often collaborate to implement strategies for prevention, treatment, and containment to protect public health and minimize the impact on communities.
