Throughout the world, recognition of the importance of public health to sustainable, safe and
healthy societies is growing. The achievements of public health in nineteenth-century Europe were
for much of the twentieth century overshadowed by advances in personal care, in particular in
hospital care. Now, with the dawning of a new century, there is increasing understanding of the
inevitable limits of individual health care and of the need to complement such services with effective
public health strategies. Major improvements in people’s health will come from controlling communicable
diseases, eradicating environmental hazards, improving people’s diets and enhancing the
availability and quality of effective health care. To achieve this, every country needs a cadre of knowledgeable
public health practitioners with social, political and organizational skills to lead and bring
about changes at international, national and local levels.
This is one of a series of 20 books that provides a foundation for those wishing to join in and
contribute to the twenty-first-century regeneration of public health, helping to put the concerns and
perspectives of public health at the heart of policy-making and service provision. While each book
stands alone, together they provide a comprehensive account of the three main aims of public health:
protecting the public from environmental hazards, improving the health of the public and ensuring
high quality health services are available to all. Some of the books focus on methods, others on key
topics. They have been written by staff at the London School of Hygiene & Tropical Medicine with
considerable experience of teaching public health to students from low, middle and high income
countries. Much of the material has been developed and tested with postgraduate students both in
face-to-face teaching and through distance learning.
The books are designed for self-directed learning. Each chapter has explicit learning objectives, key
terms are highlighted and the text contains many activities to enable the reader to test their own
understanding of the ideas and material covered. Written in a clear and accessible style, the series will
be essential reading for students taking postgraduate courses in public health and will also be of
interest to public health practitioners and policy-makers.
