Medical Definition of Horizontal survey
1.
A study of a community, perhaps stratified by age, sex, ethnicity etc., but at one point in time or over a short time interval.
Although a snapshot, horizontal surveys of prevalence and intensity within different age classes of a community can nevertheless provide valuable information on the rate at which hosts acquire infection through time, provided that the host and parasite populations have remained approximately stable for a period of time (i.e. Stable endemicity). Same as cross-sectional study , converse of longitudinal study.
