A pandemic is an outbreak of a disease that spreads globally and affects a large number of people. Pandemics can have significant impacts on public health, economies, and social systems. They are caused by infectious agents, such as viruses or bacteria, and can spread rapidly due to globalization and travel. During a pandemic, governments and health organizations implement various measures to control the spread of the disease, such as quarantine, social distancing, and vaccination campaigns. Pandemics throughout history, such as the COVID-19 pandemic, have demonstrated the importance of preparedness, international cooperation, and research in combating these global health challenges.
