Infectious diseases epidemiology

In this glossary the authors have reviewed old and new terms contemporarily used in the infectious disease epidemiology. Many of these concepts were established throughout the 19th century and at the beginning of the 20th century (classic terms), however, the meanings of old terms have been revised and new terms are continually being added. This glossary has therefore reviewed the classic and the more recently established terminology defining the most relevant terms contemporarily used in this field.
