Water-related disease

In Nunavik, common practices such as the consumption of untreated water and raw game may promote exposure to pathogenic agents responsible for zoonoses, infections that may be transmitted from animals to humans, as well as for food-borne and water-borne infections. As part of the 2004 Nunavik Inuit Health Survey, information was gathered to depict the supply of drinking water and to determine the prevalence of certain infections among the Inuit population, including gastroenteritis.

The results reveal that the region and socioeconomic characteristics (age, education and revenue) of the main respondents (n = 521) were associated with the supply of drinking water in households (source of drinking water, type of treatment used in the house and frequency of cleaning the domestic reservoir).

This notice responds to a request from the ministère de la Santé et des Services sociaux (department of health) of Québec. It is the result of the concerted efforts of two teams within the Institut national de santé publique du Québec (national institute of public health): the “Biohazard, environmental and occupational risks” team wrote the “legionellosis” section, and the “Safety and injury prevention” team wrote the “scalding” section.

Based on an analysis of the scientific literature and the data available in Québec, the Institute believes that preventing tap water scalds is as important as preventing legionellosis. These problems have similar consequences from a public health perspective and in both cases there are well-known, effective or promising prevention measures.
