Epidemiology and Disease Outbreak

The amount of a particular disease that is usually present in a community is introduced   to as the baseline or endemic level of the disease. While some diseases are so rare in a given population that a single case warrants an epidemiologic transition, other diseases occur more commonly so that only deviations from the norm warrant investigation. Sporadic refers to a disease that take place infrequently and irregularly.
