Prevalence. Prevalences . Prevalence Rate . The total number of cases of a given disease in a specified population at a designated time. It is differentiated from INCIDENCE, which refers to the number of new cases in the population at a given time. . 1.00
/epidemiology. /endemics . /epidemics . /frequency . /incidence . /morbidity . /occurrence . /outbreaks . /prevalence . /surveillance . Used with human and veterinary diseases for the distribution of disease, factors which cause disease, and the attributes of disease in defined populations; includes incidence, frequency, prevalence, endemic and epidemic outbreaks; also surveys and estimates of morbidity in geographic areas and in specified populations. Used also with geographical headings for the location of epidemiologic aspects of a disease. Excludes mortality for which "mortality" is used. . 1.00
Prevalence Ratio. Approximation of the relative risk, given by the prevalence of the disease (injury or death) among patients compared to the prevalence among unexposed people to the factor under study. It is usually estimated for cross-sectional studies. . 0.79

Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with LONGITUDINAL STUDIES which are followed over a period of time. . 0.75

Studies, Seroepidemiological . Study, Seroepidemiological . Seroprevalence . EPIDEMIOLOGIC STUDIES based on the detection through serological testing of characteristic change in the serum level of specific ANTIBODIES. Latent subclinical infections and carrier states can thus be detected in addition to clinically overt cases. . 0.64
