Trachoma in northern Ghana: a need for further studies

The northern Ghana Upper East Region [UER], Upper West Region [UWR], and Northern Region (NR) lie within the African trachoma belt. The 3 regions share common features of poverty, dryness, dusty environments, and poor environmental hygiene. Trachoma has been identified previously in the NR and the UWR as a disease of public health importance and a control program is underway.

To establish baseline prevalence and risk factor parameters in the Upper East for possible control of trachoma in the region.

Population-based cross-sectional survey using multi-staged cluster sampling techniques was used. In all 26,323 participants from 4,374 households in 160 communities were examined with a 2.5x magnifying binocular loupe for trachoma; 7,763 were children aged 1-9 years and 15,191 were aged 15 years and over.

Only 3 children were identified with active trachoma (trachoma with follicles, TF = 1; trachoma with intense inflammation, TI = 2) giving regional prevalence of 0.01% (Confidence Limits, CL: 0.0-0.1) for TF and 0.03% (CL: 0.0-0.1) for TI. Trachomatous trichiasis was measured at 0.05% (CL: 0.0-0.1) while children with clean faces was measured at 95.5%. Only 3.6% of the examined households in the region had access to a toilet facility.

Trachoma is not a disease of public health importance in the UER of Ghana despite being in a trachoma endemic zone and sharing the necessary risk factors for the disease.
