One of the local improvements has involved drinking water.
A randomized, blinded, controlled trial investigating the gastrointestinal health effects of drinking water quality.
Less than half of the people performed any type of treatment on their household drinking water before use.
Drinking water had to be brought from the nearby rivers.
Also, the presence of bacteriophages in drinking water and subsequently in natural biofilms may not predict the presence of pathogenic viruses.
In part this practice is related to the poor quality of drinking water.
Results of the test suggested that we could not reject the presence of endogeneity for those households treating drinking water.
The lower rates in urban areas may be related both to improved socioeconomic status and to improved sources of drinking water.
