Investigation of communities at increased risk of trachoma recrudescence & a model post-elimination surveillance strategy

Primary research question

Is there evidence of on-going or recent ocular Ct transmission in communities of northern Ghana felt to be at increased risk of recrudescence, at least two years since they were identified with Ct infection and or high anti-Pgp3 seroprevalence during pre-validation trachoma surveillance surveys?

Secondary research questions

What is the geographical extent of the boundaries of any persistent Ct infection and on-going transmission in the post-elimination setting?

What is the community-level (anti-Pgp3) prevalence of seropositivity for the multiplex bead array (MBA) (and possibly ELISA) as compared to the lateral flow assay (LFA)?
