Indicators of water supply and water transmission diseases in Eastern Amazonian municipalities

ABSTRACT

The objective of the research was to correlate operational water supply indicators with the frequency of diseases with compulsory notification of water transmission in six municipalities in the state of Amapá/Brazil. The methodology consisted of the statistical treatment of data on diseases with compulsory notification of water transmission, made available by the Health Superintendence of Surveillance of Amapá (Superintendência de Vigilância em Saúde do Amapá) (period from 2007 to 2017), with operational water supply indicators consolidated by the National Sanitation Information System (Sistema Nacional de Informações sobre Saneamento) (period from 1996 to 2017). The results showed, through a series of regressions, that six out of twenty operational indicators, presented significance and positive correlation with acute diarrheal diseases, regardless of the municipality (R_aj² = 0.75, p < 0.05), with a progressive trend of these diseases with the expansion of basic sanitation services. We concluded that the six operational indicators showed a positive correlation with acute diarrheal diseases. However, despite the expansion of the operating system of water supply in the period, there was also an increase in these diseases, suggesting a growing temporal trend of the basic sanitation deficit offered in these municipalities.
