Section 10: d. How can we protect ourselves against infectious diseases?

|
Objectives |
| Children should learn: |
- to identify patterns in data from secondary sources and to try to explain them
- to organise facts/ideas/information in an appropriate sequence
|
Activities |
|
Outcomes |
|
Children: |
- Provide pupils with secondary data on the incidence of a major childhood disease,
eg diphtheria from 1910 to 1955 in a city location. Ask them to relate patterns to the introduction of immunisation and the start of a free health service.
- Ask pupils to find out about programmes of routine immunisations using reference materials, ICT and the internet. Use the information to write a magazine article about the advantages and disadvantages of routine immunisations.
|
|
- describe how the incidence of,
eg diphtheria, varied over the period and relate changes to social changes,
eg the introduction of immunisation
- present a point of view in writing, using statistical evidence and linking points persuasively
|
|
Points to note |
- Statistics on disease incidence are available in government reports such as those of the chief medical officer, available from HMSO bookshops.
- Some teachers may want to go further and discuss why some immunisations need boosters every few years,
eg against tetanus, while others,
eg against cholera, are not very effective. The relationship between the incidence of infectious disease and other factors,
eg diet, is explored further in unit 9B 'Fit and healthy'.
