• Summary:

• Poor water quality, sanitation and hygiene account for some 1.7 million deaths a year worldwide, mainly through infectious diarrhoea. Infections that do not occur in healthy persons due to the low pathogenicity or concentration of the microorganisms are more likely to occur in immunocompromised patients. The main objective of the water supply sector has always been to improve people's health by providing access to safe water supply and sanitation, so the growing number of immunosuppressed people, mainly in developing countries, makes it necessary to develop new concepts to protect these patients from infectious agents in drinking water.
