Epidemic and Pandemic

An epidemic occurs when one disease rapidly spreads, or increases in occurrence among many people at the same time—spreading from person to person in a locality where the disease is not permanently prevalent.

Herd immunity, also referred to as ‘community immunity’, is a phenomenon where a large part of an area or a community of people become immune to an infectious disease, which effectively stops the disease from spreading and protects the entire community.

Flattening the curve

The exponential rise in the number of positive cases of COVID-19 has exerted immense pressure on the health care system of several countries. Flattening the curve is said to be the best possible option to ease this pressure and treat affected people efficiently.
