Information from these households thus presents an opportunity to understand the health and socio-economic characteristics of the population served by the Mosoriot health centre. The Mosoriot Rural Health Training Centre is located approximately 25 kilometers south of Eldoret town and is the main health care provider in Kosirai Division. The health centre provides primary care services and is mainly an outpatient facility. In addition, a collaboration between Indiana University and the Moi University Faculty of Health Sciences has established an electronic medical record system (MMRS) at Mosoriot which contains a range of clinical information on all patients who visit the health centre (Hannan, et al. 2000). In 2001, this same collaboration also created the Academic Model for the Prevention and Treatment of HIV/AIDS (AMPATH). AMPATH's first rural HIV clinic was opened in Mosoriot in November 2001 (Cohen, 2004). Beginning in late-2003, the HIV clinic at Mosoriot has experienced tremendous growth, with the number of patients rising from less than 100 in 2003 to over 800 as of October 2004 (AMPATH data).
