Explain the difference between public health interventions delivered at the ecological and individual levels, using one example for each
Childhood immunisation is an example of an individual level intervention - the injection is delivered to each individual child so the intervention solely affects their health
Building a playground for a local community is an example of a community level intervention - the playground would provide a place for children within the community to exercise and socialise, benefiting the health of individual in a particular area
