While strategies are the general plans of action used to carry out a prevention program, a method is a tactic employed to implement the strategy. Hence, while education may be a strategy for the prevention of domestic injury, direct mail, lectures, media advertising, etc. are all possible methods of implementing the strategy. The term 'counter-measures' is often usedin injury prevention synonymously with prevention 'methods'.
There are three generally accepted strategies, and several methods or counter-measures of injury prevention. The three strategies are:
- education/behaviour change;
- legislation/enforcement; and
- engineering/technology.
 Strategies should be selected in a combination determined from an appropriate analysis of the situation. The strategy mix can also depend on the temporal sequence of injury, i.e. pre-event, event or post-event. In general, the three strategies interact with the epidemiological triad of host, vector (or vehicle) and environment in the manner illustrated in Figure 3.4.
