004 - Water and Vector Borne Diseases

Geographic Knowledge and Understanding

Geographic factors contributing to the incidence, diffusion and impacts (demographic and socio-economic) of vector-borne and water-borne diseases.

Detailed Examples

One detailed example of a vector-borne disease and one detailed example of a water-borne disease.


Understanding the processes behind the incidence and diffusion vector and water borne diseases can create the possibility to change the impact.


  • To have knowledge and understanding of how vector and water borne diseases are spread.

  • To have knowledge and understanding of the occurrence of vector and water borne diseases.

  • To have knowledge and understanding of the demographic and social-economic impacts of vector and water borne diseases.

  • To create a detailed example of a water-borne disease.

  • To create a detailed example of a vector-borne disease.

Key Terminology

            • Vector-borne diseases

            • Water-borne diseases

Define the key terms above by using the 'Useful Links' below.

Useful Links

Activity One - Comprehension - Water-Borne Diseases

We have already explored how diseases can be generally spread and what can make people more vulnerable than others. We are now going to focus specifically on water-borne diseases. The first section is going to look at who is at the most risk along, how the diseases are generally spread and the impacts than occur.

      1. Using the first YouTube clip describe what diarrhoea is and how it occurs.

      2. Using the maps in the 'Useful Resources' box and the WHO article, describe the global distribution of the burden of diseases and mortality from water and sanitation.

      3. How can water-borne diseases be linked to the idea of diseases of poverty?

      4. Using the article by the WHO, how many people die across the world from diarrhoea?

      5. What are the causes of diarrhoea?

      6. Using the Codrington textbook Page 61, how is diarrhoea spread?

      7. How can diarrhoea be prevented?

      8. Read the article by the BBC and describe the changes in the incidence of diarrhoea from 2005 to 2015.

      9. Using the final article in the 'Useful Resources' box and your own research create a detailed example of the causes, spread and consequences of Cholera.

Activity Two - Comprehension - Vector-Borne Diseases

We are initially going to find out the basics of what a vector-borne disease is and how diseases are spread this way.

      1. Make notes on what a vector-borne disease is, how the disease can be spread and how increased global links can make the incidence more prevalent. Use the Codrington textbook to help you.

Activity Three - Detailed Case Study - Malaria a Vector-Borne Disease

We are going to be focusing on malaria as a vector-borne diseases, but why are we focusing on this?

      1. You have 5 minutes to find as many newspaper headings as you can that mention malaria. We will then discuss the findings.

      2. Watch the first YouTube clip and describe the devastating effect of malaria.

      3. Watch the second YouTube clip and describe how malaria is spread around the body.

      4. As geographers we all like a map, using image three describe the changing global spread of malaria from 1990 to 2085.

      5. Make a copy of the table below and explain how the geographic factors impact the incidence of malaria.

      6. Create a detailed example of how malaria is having a devastating impact on a community. Try and include the following:

                • Where

                • Why is malaria occurring there.

                • What is the impact - Social, Economic, Environmental and Political

                • Prevention

Incidence of Malaria

What does malaria do to the body?
