Answer-1:- An epidemic refers to a sudden increase in the number of cases of a disease above what is normally expected in a specific geographic area or population. The term is typically used to describe the spread of infectious diseases, but can also apply to the spread of non-communicable diseases such as heart disease, cancer, or diabetes.
A pandemic, on the other hand, refers to a global epidemic. It is a worldwide spread of a new disease. A pandemic can occur when a new virus or strain of a disease that has never been seen before emerges and spreads from person to person across countries or continents. The rapid spread of a new and highly infectious disease can have serious public health and economic Consequences.
