# Public Health ISS
PHISS is a core IMIS module designed to help municipalities monitor and address public health and sanitation challenges. It facilitates the collection and maintenance of water sample data from groundwater, surface water, and treated wastewater, ensuring compliance with water contamination standards and supporting CWIS environmental monitoring objectives.
PHISS also tracks waterborne disease cases (e.g., diarrhea, cholera, dysentery, typhoid) and identifies hotspot areas, including associated fatalities, enabling municipalities to conduct spatial analysis and implement targeted interventions.
The module supports CWIS indicators by monitoring:
Water contamination compliance across different water sources.
Incidence of faecal-oral diseases to assess sanitation system effectiveness.
PHISS provides data export tools for CSV, Shape, and KML formats, allowing municipalities to utilize the data for strategic planning and resource allocation to reduce public health risks.
# Introduction to Public Health ISS
PHISS is another core module of the IMIS, designed to empower municipalities in monitoring and addressing public health and sanitation challenges. PHISS enables the collection and maintenance of water sample data from various sources, including groundwater, surface water, and treated wastewater, to ensure compliance with water contamination standards. This functionality directly aligns with the CWIS objective of monitoring environmental outcomes associated with sanitation systems. Additionally, PHISS records and tracks cases of waterborne diseases across the city, providing municipalities with crucial data to understand and mitigate public health risks.
One of the standout features of PHISS is its ability to maintain spatial and attribute data related to hotspot areas where waterborne diseases, such as diarrhea, cholera, dysentery, and typhoid, have been detected. The system also tracks fatalities linked to these diseases, offering a comprehensive overview of the impact on affected households and populations. By integrating this information with the UDSS municipal authorities can conduct detailed analyses of disease prevalence and its underlying causes. This data-driven approach enables strategic planning, targeted interventions, and efficient allocation of resources to reduce health risks in vulnerable areas.
Water sample data and waterborne cases data maintained by PHISS helps municipality to monitor the CWIS indicators (i) Water contamination compliance of the water sources such as groundwater, surface water and treated wastewater, and (ii) Incidence of fecal-oral pathway diseases (e.g. diarrhea, cholera, dysentery and typhoid). With this information, municipalities can assess the effectiveness of sanitation systems in protecting public health and identify areas requiring urgent attention. By addressing these indicators, PHISS supports municipalities in achieving CWIS objectives, ensuring safe water quality and reducing the prevalence of sanitation-related diseases. The data export tools under PHISS allow users to export data in CSV, Shape and KML format where applicable.
# 19.1 Water Samples
Water Samples sub-module maintains the information regarding the water quality testing with a focus on coliform bacteria levels as an initial indicator of potential water contamination. This module records the spatial location where the samples were taken.
