Public health nurses make up the largest segment of the public health industry. These necessary healthcare professionals are responsible for all facets of public health care, including prevention, activism, education, assessment, and evaluation. We rely on public health nurses to prevent diseases while promoting health and safety within the community. If you are currently in a nursing program or you are considering becoming a nurse, making the transition to public nurse offers plenty of rewards. Not only will you have the opportunity to make significant changes to public health, but you have the potential to help generations of people live longer, healthier lives. While public health nurses only help a single patient at a time, the role may also have you caring for entire populations, making this job one of the most important employment positions in the healthcare industry.
