finding patterns in the spread of disease.

Explanation:

Epidemiology involves the incidence and trend of health problems happening in a community. The resultant prevalence helps epidemiologists to assess the incidence of the disease among diverse communities. Cycle relates to the frequency of activities linked to healthcare by period, location, and person.

Basic epidemiological approaches continue to focus on close evaluation and the use of appropriate reference groups to determine how what has been reported, such as the amount of disease cases in a geographical region during a given period of tenure,, or the level of influence to people with illness, varies from what would be predicted.
