A pandemic is a global outbreak of a disease that spreads rapidly across a large region, crossing international boundaries and typically affecting a significant portion of the population. Unlike an epidemic, which is confined to a specific area or country, a pandemic spans multiple countries or continents. Pandemics can be caused by viruses, bacteria, or other pathogens that are easily transmitted from person to person, often through respiratory droplets, direct contact, or contaminated surfaces. Historical examples include the 1918 influenza pandemic and the H1N1 influenza outbreak in 2009. The most recent example is the COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, which emerged in late 2019 and led to widespread health, economic, and social disruptions globally. Managing a pandemic involves coordination of international public health responses, including disease surveillance, testing, containment measures, vaccination programs, and public education on hygiene practices to mitigate the spread of the disease.
