The theme of SEED SHOWCASE 2021 is about the endemic, epidemic and pandemic. Endemic is used to describe a disease that is present at an approximately constant level within a society or country. Epidemic is a term used to describe a situation where a disease spreads rapidly to a large number of people in a given population over a short time period. Pandemic is the term used to describe the rapid spread of a transmissible infectious/communicable disease over several continents or worldwide. Once an epidemic becomes global and affects a large per cent of the population it becomes known as a pandemic.
