Pandemic

A pandemic is an outbreak of a disease that occurs on a global scale, affecting a large number of people across multiple countries or continents. It typically refers to infectious diseases that spread easily from person to person, leading to widespread transmission. Unlike an epidemic, which is confined to a specific region or population, a pandemic has a far-reaching impact, often resulting in significant health, social, and economic consequences. The classification of a disease as a pandemic is influenced by various factors, including the severity of the disease, the ease of transmission, and the geographic spread. The World Health Organization (WHO) often plays a key role in declaring a pandemic, as seen with the COVID-19 outbreak, which exemplified the criteria of a highly transmissible virus causing illness in multiple countries. Pandemics also require coordinated international responses to manage and mitigate their effects on public health systems and society as a whole.
