In public health Policy rather than considering the health of the individual we will consider the health of the entire community or certain population. It mainly focus on preventing infectious disease, removing contaminants from food and drinking water, reducing pollutions, by public health policies (for example administering vaccines for various diseases) etc since they can affect the entire community.
