Epidemiology

Incidence and prevalence are terms commonly used in describing disease epidemiology. Incidence is newly diagnosed cases, which can be expressed as new cases per year per million people. Prevalence is the number of cases alive, which may be expressed in terms of existing cases per million over a period of time. The percentage of babies in developed countries with milk allergy is between 2% and 3%. This estimate is for antibody-based allergy; figures for allergy based on cellular immunity are unknown. The percentage declines as children age. National survey data in the U.S. collected from 2005 to 2006 showed that from age six and older, the percentage with IgE-confirmed milk allergy was less than 0.4%. For all age groups, a review conducted in Europe estimated that 0.6% had milk allergy.
