Epidemiology of skin diseases in Germany: systematic review of the current state of research - part 3: infectious skin diseases

The aim of this work was to systematically collect all previously published population-based epidemiological data on skin diseases in Germany. A systematic literature search was performed using PubMed/MEDLINE for the period of the last 15 years. With the aim to include all dermatological diseases, a diagnostic list based on the ICD-11 catalogue was compiled. This list included 1,347 skin diseases and formed the basis for the search. The present part 3 of the publication series deals with infectious skin diseases. The results on cutaneous tumor diseases (part 1) and non-infectious skin diseases (part 2) form the other parts of this publication series. The literature search yielded 4,605 hits, of which 72 papers on 43 different skin diseases were included in the synthesis. Among them were twelve hits on infectious dermatoses, of which six papers were related to measles. The highest lifetime prevalence rates were found for varicella and verrucae vulgaris. This work is the first systematic literature review that aimed to report all available epidemiological data on skin diseases in Germany. It was found that representative data on many infectious diseases are not yet available. Among the included studies, a high heterogeneity was found with regard to the methodology. Nevertheless, these epidemiological data have a wide range of uses and can serve as a reference for various epidemiological questions.
