title: [Sex differences in infectious diseases and their clinical consequences].
abstract: Differences between women and men range from their anatomy, their natural social behavior to their susceptibility and response to different pathologies, including infectious diseases. The underlying mechanisms of sex differences in infectious diseases are manifold, including differences in exposure to common pathogens, genetic factors that modulate immune responses against pathogens and hormonal factors that may alter susceptibility or disease progression, and responsiveness to treatment. On one hand, these mechanisms lead to higher innate and adaptive immune responses in females, which result in faster clearance of acute infections and higher antibody responses to several vaccines, on the other hand this contributes to an increased susceptibility to chronic inflammatory diseases. In this review we summarize the underlying causes of sex differences in prevalence, clinical course of disease and treatment outcome of infectious diseases. In order to develop individualized treatment concepts, a fair balance between the sexes should be maintained in basic science, preclinical and clinical studies.
