The hygiene hypothesis postulates that an environment with a high incidence of infectious
diseases protects against allergic and autoimmune diseases, whereas hygienic
surroundings increase the incidence of these disorders. This review examines the evidence
in support of the hygiene hypothesis and offers a number of mechanisms that could explain
the relation between sanitary conditions and susceptibility to allergic and autoimmune
diseases.
