Impact of a ceramic pot point-of-use water treatment device on rural people living with HIV and AIDS
Expanded Title:The consumption of contaminated water can result in increased incidence of waterborne diarrhoea, a leading cause of morbidity as well as mortality worldwide. Immuno-compromised people exposed to microbial contaminated water are more likely to experience adverse health effects. It has been reported that up to 60% of persons affected with HIV and AIDS in developed countries report diarrhoea frequently of which 5 to 16% of these cases are related to Cryptosporidium, a waterborne protozoan pathogen that can cause chronic and life-threatening diarrhoeal illness in people living with HIV and AIDS. This study investigated whether improved household drinking water at the point-of-use will improve the well-being of people living with HIV and AIDS. The effectiveness of the clay filter to improve the household water quality has been demonstrated in this study. However, it is necessary that the standard of production and quality control remain at a constant level for the ceramic filters in order to work efficiently. In addition, it is important for people to change their attitudes with regard to point-of-use intervention devices. The filters were highly effective in reducing microbial indictor microorganisms, but in some households, the filters were subject to recontamination due to unhygienic household practices. Therefore people need to be educated on sanitation and hygiene aspects with regards to improving their well-being. Although the pathogens which were detected were prevalent in the water and the faecal matter, exact deductions could not be made regarding the link between presence and infection using the Bio-wipe kit in the investigation of diarrhoeal samples. It was difficult to determine the impact of improved microbial water quality on the health of people living with HIV and AIDS, in rural households, as measured by the incidence of diarrhoea and improved immune status because of the use of ARVs and other factors which could impact the well-being of the infected HIV and AIDS person
