Question

Which study design was used to conduct this study? Be specific in describing the study design (ie prospective cohort, experimental, case-control, etc). A university epidemiologist is interested in understanding why some patients with West Nile Virus (WNV) develop severe symptoms, such as meningitis, while the vast majority of patients infected do not. Patients with documented severe WNV outcomes were located, and then matched by age and gender to persons with documented mild WNV outcomes. Demographic data, prior health history, medications, occupation, and underlying immune function data was collected on both groups.

Explanation / Answer

The study design used in this study is case conrol study design. In this design two groups are studied which have same disease but different exposures and outcomes. So the case control study design describes above type of study in a better way.
