In order to achieve the goals of our study, we now propose to identify other more remote villages with trachoma infection rates of 20% or more to evaluate the effect of community-wide treatment with single dose of oral azithromycin. If one or more of these villages (dependent upon population) has trachoma rates of 20% or more they will be invited to participate in the azithromycin treatment. In one set of subjects (1 or 2 villages, dependent upon population and infection rate) we will perform treatment, and follow them up at 2-, 12-, and 24-months post-treatment to ascertain infection rates. In a second set of subjects (1 or 2 villages, dependent upon population and infection rate) we will perform treatment, then perform re-treatment at 30-days post initial treatment, and follow them up at 2-, 12-, and 24-months post-treatment to ascertain infection rates. This should help us determine the need for/and the best time for re-treatment to eliminate blinding trachoma, as some recent studies suggest there is a 2-4% failure rate in the initial treatment. In sum, this study should provide a rational approach to use of community-wide azithromycin treatment to eliminate blinding trachoma as a public health problem
