Deteriorating water treatment facilities and distribution systems pose a significant public health threat, particularly in republics of the former Soviet Union.
Interventions to decrease the disease burden associated with these water systems range from upgrading distribution networks to installing reverse osmosis technology.
To provide insight into this decision process, we conducted a randomized intervention study to provide epidemiologic data for water policy decisions in Nukus, Uzbekistan, where drinking water quality is suboptimal.
We interviewed residents of 240 households, 120 with and 120 without access to municipal piped water.
Residents of 62 households without piped water were trained to chlorinate their drinking water at home in a narrow-necked water container with a spout.
All study subjects (1583 individuals) were monitored biweekly for self-reported diarrheal illness over a period of 9.5 weeks.
The home chlorination intervention group had the lowest diarrheal rate (28.8/1,000 subjects/month) despite lack of access to piped water in their homes.
Compared with the two groups that did not receive the intervention this rate was one-sixth that of the group with no piped water (179.2/1,000 subjects/month) and one-third that of the households with piped water (75.5/1,000 subjects/month). (...)
