Quizplus · Accepted Answer

An outbreak is defined as a sudden increase in the number of cases of a disease in a particular geographic area or population, compared to what is typically expected. This increase can be caused by a variety of factors, such as the introduction of a new pathogen, changes in environmental conditions or human behavior, or a breakdown in public health measures. Endemic refers to the constant presence and/or usual prevalence of a disease within a geographic area or population. A pandemic is a global outbreak of a disease, affecting people in multiple countries or continents. A zoonosis is a disease that can be transmitted between animals and humans.
