IMPORTANCE OF INTRADOMICILIARY PARAMETERS AND POTENTIAL VECTORS ON THE OCCURRENCE OF DERMATOSES IN BRAZZAVILLE

Skin diseases are increasingly a public health problem in many countries, particularly in Africa. The dermatoses identified have often revealed various etiologies and many arthropods may be responsible. A study was conducted in the city of Brazzaville, in order to determine the types of arthropods involved in certain immuno-allergic dermatoses and to evaluate the conditions characterizing the aggression of human skin by them. The study was carried out mainly in an indoor nursing home, following consultations at the health center. A total of 43 patients out of a total of 603 people followed were found to be carriers of dermatitis, or 37% of them. The H / F ratio was 0.59, with an average age of 13.69 ? 16 years. Atopic dermatitis was most common with (74.41%) followed by Prurigo Strophilus (16.27%). A total of 668 arthropod specimens were obtained including 96.85% mites and 3.14% insects. It appeared that Ixodes ricinus is the most abundant species with a rate of 84% followed by Blomia tropicalis with 12.7%. The average temperature during the observations was evaluated at 28 ? C while the average humidity was 50% RH.
