[Epidemiological course of trachoma in Djibouti].

Abstract

A survey on a representative sample of population showed that inflammatory trachoma is rare in Republic of Djibouti. However, it is significatively more frequent in rural surroundings (0.4%, standard rates) than in urban surroundings (0.4%, standard rates) where it affects particularly people recently coming from border countries. In rural surroundings the frequency changes according to the distances from capital (p = 0.01). On the contrary, cicatricial trachoma is more frequent in the city (16.4%) than in rural surroundings (8.2%--Standard rates). The blindnesses caused by trachoma are relatively rare (0.1%) when entropiontrichiasis appear especially in urban surroundings (0.7%) where people from Arab Peninsula are the most affected (p = 0.008). When comparing with the 1968 situation, we notice a perceptible decrease of the prevalence of trachoma and also the disappearing of ethnic differences which existed at that time concerning the illness active forms. This good evolution is probably due to the effects of several mass campaigns added to an improvement of accessibility to medical care.
