Public Health

In America, there is a desperate need for an increase in public health. This can focus on an individual, group, or a community. There are are many ways an individual can be deprived of a healthy lifestyle. This can range from education to a stable ecosystem. Education can determine an individual's health based on the knowledge of how to be healthy, or it can stem from the quality or amount of education received which can lead to an increase or decrease in finances that would allow more access to health care services. Having a stable ecosystem can include things such as the quality of air that is breathed in or the amount of water available for a community.
There are many different types of interventions that can reduce the threats to health. There are three subcategories of these interventions. Primary interventions include immunizations which prevent the disease or an injury from ever taking place. Secondary interventions reduce the impact of a disease or injury that has already occurred, so that could be early onset screenings for autism or cancer. Finally there are tertiary interventions that limit the impact of an ongoing illness or injury's lasting effects. This is what a typical rehabilitation model looks like. For example a patient who had a stroke regaining muscle strength in her arm would be tertiary intervention.
