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)?

Is Preventive Chemotherapy for NTDs Really “Pro-Poor?”: Insights from the Demographic and Health Surveys

To use DHS data from 40 countries to examine the extent to which deworming of children 1-4 years is associated with: 1) a range of individual- and family-related socioeconomic indicators, including wealth quintile and maternal education; and 2) access to health systems that could provide opportunities for deworming, independent of family-level socioeconomic status.
