The epidemiology of trachoma in rural Kenya : variation in prevalence with lifestyle and environment.
A goal of the surveys was to determine the overall geographic distribution and severity of trachoma throughout Kenya.
Using a random cluster household sampling technique, 13,803 people of all ages and of diverse cultural and ethnic backgrounds were identified in eight regions of Kenya.
A detailed examination for active and inactive trachoma was carried out on each person surveyed as part of the general ocular examination.
The prevalence rate of visual loss (<20/60) due to trachoma in the better eye was 7.2/1000.
Active trachoma was present in 19% of all persons examined, and 50% of all those with trachoma were found to have moderate to severe inflammation.
Prevalence varied according to survey region from less than 1% in four regions where agriculture is the economic base, to 57% and 63% in two arid pastoral regions.
Trachoma prevalence varied from 28% in children younger than 3 years of age to 11% in persons older than 60 years of age.
Potentially blinding eyelid deformities secondary to chronic trachoma occurred in 5.0% of the rural population, and 1.2% of the rural population displayed associated corneal scarring.
Lid scarring, corneal scarring, and lid deformities were greater in prevalence among females of all age groups when compared with males.
