
This means tracking changes in the health of
the population and alerting people to
potential problems.
An example of this could be HIV, to monitor
the health of the population with HIV tracking
the number of people with HIV within the
population will help the NHS find out the
population of people with HIV in order for
them to take further actions.

3. 

To identify the health needs of the population
the trends patterns need to be established
that way the implications for the serving can
be identified.
Example: to prevent people from getting HIV
the government and NHS can provide free
condoms to adults and young people, also in
NHS hospitals every patient should use a new
and clean needle each time the have an
injection.

4. 

This means attempting to reduce the levels of
ill health, by introducing new programmes
which identify people as being ‘at risk’ of a
condition and engaging them with
preventative programmes.
An example programme that the government
and NHS might use could be to get people
tested for HIV is free vaccination to people
who don’t have HIV, so they don’t get
affected by the disease.

5. 

This mean reducing the impact of infection
disease through immunisation and other
control measure.
Example: HIV can be controlled by tracking
the number of people affected, the
government can provide subsidise drugs to
people with HIV.

6. Health promoting activities to reduce ill health
in the population.
Example: the NHS can provide people with free
condoms, there should be TV advisement to
prevent young people from sleeping
around, and they should also provide vacines.

7. 

Assessing the provision of relevant health
serving and wherether or not they are having
sufficient impact on the problem.
Example: if the hospitals do not follow the
procedures given in order to reduce the risk
of HIV, then they fail and the government
have to come up with another plan.
