Water and sanitation related diseases

As we saw in the video, there are four different categories of diseases related to poor sanitation and water supply.

• Waterborne diseases (e.g. cholera and typhoid)
• Water-washed diseases (e.g. trachoma, typhus, and ascariasis)
• Water-based diseases (e.g. bilharzia)
• Water related vector diseases (e.g. dengue fever and yellow fever)

We will look at preventative measures used to fight these diseases, such as the following:

• Protecting water sources from dangerous organisms
• Developing effective sanitation systems
• Promoting hygiene education

Thinking about the country you live in:

• Are water based diseases common in your country?
• Why/why not?
• Think about any changes in your country over time that helped protect against these types of diseases.
