H4 · Unsafe water or sanitation
Risk Infection and community health
Definition
Poor water or waste disposal raises the chance of illness.- Contaminated sources
- poor waste disposal
- flooding
- Diarrhea outbreaks
- skin disease
- dirty water
📋 Scenario
A village uses an open well close to a pit latrine.
Subjective (S): Villager: "We drink from the well."
Objective (O): Open well 5 meters from a pit latrine; water cloudy; no water treatment; no diarrhea cases reported yet.
Assessment tools for this scenario: CP-INFECT Infection Check
Validated scales to consider: qSOFA / sepsis screen
**CarePath diagnosis:** Unsafe water or sanitation related to a contaminated source and poor waste disposal (risk factors); no signs of the problem are present yet.
**Interventions and rationale**
| Intervention | Rationale |
|---|---|
| Teach boiling and treatment of water. | Boiling or treating water kills or removes germs that cause diarrhea and other diseases, giving households a safe drink even if the source stays contaminated. |
| Improve sanitation. | Moving waste away from drinking sources, for example by safer latrine placement, stops germs from seeping into the water supply. |
| Report. | Reporting tells the health and water authorities about the hazard so they can test the well and give resources or enforce safer practices. |
| Educate the community. | Community understanding of how water spreads disease helps people keep safe habits, support changes and teach others, which lasts longer than a one-time intervention. |
**Expected outcomes**
- No diarrhea cases develop.
- Diarrhea cases fall.
- Community states hygiene steps.
**Linking the data to the diagnosis**
This is a risk diagnosis, because no one has fallen ill yet. The open well is 5 meters from a pit latrine, the water is cloudy, there is no water treatment, and a villager says, "We drink from the well." No diarrhea cases are reported, so an actual outbreak statement would not fit; the contaminated source and poor waste disposal are the risk factors. The plan prevents illness by making water safe and improving sanitation. The aim is that safe water is supplied, diarrhea cases fall or stay low and the community states hygiene steps.
CarePath diagnosis
