Question

Quizplus · Accepted Answer

Epidemiologists are interested in understanding the patterns and causes of disease in populations. They often investigate outbreaks of infectious diseases, trying to identify the source of the outbreak and the risk factors for infection. They may also study the burden of chronic diseases in a population, looking at factors such as incidence, prevalence, and risk factors. The index case, or first known case in an outbreak, is important in understanding the spread of the disease, but locating the index case is not necessary to classify an outbreak as an epidemic. Morbidity data refers to the incidence or prevalence of disease, but does not include deaths. Epidemiology focuses on the diseases that affect populations, not just individual cases.
