A recent study in Kinshasa, DRC, suggests a link between cholera and the consumption of street-vended sachet water. The study, led by researchers including Ntondjo M. Raymond, found that this common practice may increase the risk of cholera in urban settings.

The study, a matched case control investigation, discovered that frequent consumption of sachet water was positively associated with an increased risk of cholera. The pathogens from the contaminated exterior of the sachets were found to be transmitted through direct and continuous contact with the mouth. Despite limitations such as a small sample size and not all cases being laboratory-confirmed, the findings are significant.

The authors recommend that health messaging, outbreak control measures, and epidemiological investigations should consider sachet water consumption as a potential risk factor. This is particularly important in urban settings where access to clean water may be limited.

The study highlights the potential risk of cholera transmission through sachet water consumption in urban areas. While more research is needed to confirm these findings, public health officials should be aware of this potential risk factor and include it in their messaging and investigations.
