Kongwa Trachoma Project

Does infection data add evidence to the understanding of trachoma prevalence in low endemic areas?

  1. To evaluate strategies for the elimination of trachoma by evaluating potential makers that show interruption of transmission of C. trachomatis
  2. To determine the prevalence of ocular chlamydial infection among children aged 1 – 9 years old in Mpwapwa and Kalambo District, Tanzania
  3. To determine the associated risk factors of ocular Chlamydia infection among children aged 1 – 9 years old in Mpwapwa and Kalambo District, Tanzania
  4. To determine the usability of antibody test to detect Chlamydia antigen pgp3 using lateral flow assay
  5. To examine the longevity of the antibody response to trachoma antigens in a high and low-prevalence setting

Does infection data add evidence to understanding of trachoma prevalence in low endemic areas?

To investigate the utility of an antibody test as a tool for surveillance during the elimination phase of trachoma programmes

Countries: Tanzania
Diseases: Trachoma

Field-testing a Lateral Flow Assay for anti-Chlamydial Antibody Responses

To field-test the Pgp3 lateral flow assay to compare data obtained in the field on the rapid test to that from DBS collected from the same individual tested on the Pgp3 multiplex bead array.

Diseases: Trachoma

Exploring alternative indicators for trachoma endpoint decision-making (Tanzania)

Analyze the relationships between the prevalence of the clinical sign follicular trachoma (TF) and the prevalence of infection and antibody to determine whether it may be appropriate to consider one or more alternative indicators for deciding whether trachoma programs can stop MDA.
