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)?
Improving access to Lymphatic Filariasis MMDP services through an enhanced evidence-based, cascade training model for health worker capacity strengthening in Ghana
This social science study will address the following:
Formative question: What were the successes and challenges of the LF MMDP pilot in the Upper East region for increasing the capacity of health workers of all levels and improving the ability of patients to manage LF morbidity?
Intervention question: Can a modified capacity strengthening package, developed based on the formative research results, be effective at increasing the capacity of health workers of all levels and improving the ability of patients to manage LF morbidity?
Understanding areas of increased trachoma risk (hotspots) through the implementation of a post validation trachoma surveillance strategy
To determine if there is evidence of on-going or recent transmission in the “hotspot” communities of increased risk two years after they were identified during the pre-validation surveys (clinical, antibody and infection data).
