Case-control studies have several advantages: they allow for the examination of multiple exposures for a single outcome, are suitable for studying rare diseases and those with long latency periods, require fewer case-subjects, and generally are quicker and less expensive to conduct than cohort studies, making them well suited for an outbreak investigation. They have several disadvantages: they are not appropriate for studying rare exposures, they are subject to bias because of the method used to select controls, and they do not allow the direct measure of the incidence of disease.
