The global health challenge
Y11 to Y12 Geography Induction
The global health challenge
Lesson aim:
• To provide an introduction to the links
between geography and one infectious
disease
Lesson objectives:
• To know the key terms in the study of the
geography of health
• To be able to describe and explain the global
distribution of an infectious disease (malaria).
How are geography and global health
linked?
Watch the video clip of Prof Lipkin from the 21st
Century Challenges website (1min 15 sec – 2 min 42 sec)
Key terms activity – Working as a small
group can you define all the key terms?
Key term definitions
Crude death rate
The overall condition of an individual at a given time in regard to soundness of body
or mind and freedom from disease or abnormality.
The state of being ill or diseased, or the occurrence of a disease or condition that
damages health and quality of life. It can also be used to mean the relative incidence
of a particular disease in a society.
Death. The term is often accompanied by the cause of death (a specific disease or
condition or injury).
The number of deaths of children under the age of 1 year expressed per 1000 live
births per year. It is useful as a barometer of social and environmental conditions and
is sensitive to changes in either.
The number of people dying from a disease divided by the number of those
diagnosed as having the disease.
The number of deaths per 1000 people in 1 year.
Prevalence
The number of cases of a disease per 10 000 of the population.
Incidence
Infectious
The number of cases of a disease that are confirmed annually.
A disease liable to be transmitted to people, organisms through the environment.
Non-communicative
A disease which is non-infectious.
Endemic
A disease that is prevalent to a peculiar or particular locality or region.
Pandemic
A disease that is prevalent over a whole country or the world.
Health
Morbidity
Mortality
Infant mortality
Case-mortality rate
What is malaria?
• Using the 21st Century Challenges 60 seconds
overview you have 5 minutes to synthesise
the information.
• You could highlight key information in
different colours, create a mind map or make
notes.
What is the geography behind the
facts?
• Using the key facts slide identify the geography
within these facts.
• For example 22% of childhood deaths in Africa
are caused by malaria. Link to population issues
such as high infant mortality rate, future impact
on society in terms of a reduction in working age
population, future population decline, social
costs on society, poor education, health care
costs (burden on society, access to medicine).
Malaria – key facts
Where is malaria found?
• Using the maps provided describe the global
distribution of malaria using a maximum of 4
bullet points to describe each map.

Practice examination question
Figure 1a The distribution of malaria cases by country in 2005
Describe the pattern shown in Figure 1a.
Practice examination question
Figure 1b The percentage of population
at risk of malaria
Figure 1c The percentage of
global deaths from malaria
Study Figures 1b and 1c. Explain why the percentage
of population at risk of and the percentage dying from
infectious diseases, such as malaria, varies (5 marks)
