Trachoma in northern Ghana: a need for further studies.

Background: 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.
