  • What is the difference between incidence vs. prevalence? (reference.com)
  • According to the New York State Department of Health, incidence is used to measure a patient's likelihood of being diagnosed with a disease during a period of time, while prevalence is used to measure a patient's likelihood of already having a disease. (reference.com)
  • Incidence and prevalence are statistical terms. (reference.com)
  • Incidence rate" is the number of newly diagnosed patients divided by the number of "at-risk" persons, whereas "prevalence rate" refers to the total number of patients within a population divided by the total population. (reference.com)
  • In addition to incidence and prevalence, morbidity and mortality are also statistical terms used to describe how a disease has affected a given population. (reference.com)

  • To illustrate, a long term disease that was spread widely in a community in 2002 will have a high prevalence at a given point of 2003 (assuming it has a long duration) but it might have a low incidence rate during 2003 (i.e. lots of existing cases, but not many new ones in that year). (wikipedia.org)
  • Conversely, a disease that is easily transmitted but has a short duration might spread widely during 2002 but is likely to have a low prevalence at any given point in 2003 (due to its short duration) but a high incidence during 2002 (as many people develop the disease). (wikipedia.org)
  • As such, prevalence is a useful parameter when talking about long lasting diseases, such as HIV, but incidence is more useful when talking about diseases of short duration, such as chickenpox. (wikipedia.org)

  • Editorial: The rising prevalence of autism. (nih.gov)
  • 1 Diagnostic substitution is one factor potentially contributing to the large observed increase in autism prevalence and, unlike many other possible factors, empirical evaluation of this factor can actually be approached by using existing administrative data. (aappublications.org)
  • Figure 1 shows the original plots for autism and mental retardation (MR) classification prevalences as well as plots rescaled to an arithmetic y-axis. (aappublications.org)
  • The original plots emphasize the large annual percent increase in the low-prevalence autism classification while obscuring the smaller (in percentage terms) changes in the higher-prevalence MR classification. (aappublications.org)
  • On the rescaled plots, we now can see that as autism prevalence increases with most successive birth cohort for ages 6 through 9, MR prevalence is decreasing (corresponds to the negative sign in Shattuck's models). (aappublications.org)
  • However, the graphs also demonstrate that, at least in the US aggregate data, the increases in autism classification prevalence are greater in absolute terms (the distance between lines is farther) than the MR decreases, suggesting that any offset by MR alone would not be complete. (aappublications.org)
  • In addition, at ages 10 and 11, autism prevalence still increases with successive birth cohorts but MR prevalence no longer decreases consistently. (aappublications.org)
