Abstract
Background: Infectious dermatoses are widespread in sub-Saharan Africa and are influenced by many factors. The aim was to study the epidemiological and clinical characteristics of infectious dermatoses and their associated factors in the Dermatology-Venerology Department of CHUD-B/A. Material and Methods: This was a descriptive and analytical cross-sectional study, with retrospective data collection, over a 12-year period from January 1, 2009 to December 31, 2020. The sample consisted of all patients with infectious dermatoses whose records could be used. Data were analyzed using Epi info 7.2.3.1 software. Results: A total of 1,512 records were collected for patients with at least one infectious dermatosis during the period. The mean age was 27.68 ± 15.9 years. There were almost as many men as women, with a sex ratio of 1.04. The most frequent reason for consultation was pruritus (64.55%). Mycotic dermatoses (59.46%) predominated, followed by viral dermatoses (22.75%). Unprotected sexual intercourse was a factor associated with bacterial dermatoses, multiple sexual partnerships a factor associated with viruses, and female sex a protective factor for cutaneous parasitoses. Conclusion: Infectious dermatoses play an important role in dermatological consultations, with a predominance of mycotic dermatoses. The factors associated with their occurrence are varied.
