**6.4 Environmental improvements**

Trachoma control programs advocate for improved water supply which is essential for face washing and sanitation as major contributors of successful control efforts. Latrine building is particularly advocated and incorporated because in trachoma control programs, because it limits the preferred breeding ground of the mechanical vector of *C. trachomatis, Musca sorbens*. It is to be noted that most of the changes that tend to improve the control of trachoma will also benefit the general health of the community [19, 53].
