Nurses have the ability to make a significant difference in a time when public health is facing rising challenges. The practise of public health nursing is described as the application of knowledge from the nursing, social, and public health sciences to promote and safeguard the health of populations. Nurses can have a huge impact on public health if they work together. By teaching communities and providing treatment within them, public health nurses play a crucial role in improving population health outcomes. Registered nurses in this position of leadership are able to influence positive change through policy reform and community building. Public health nurses have been on the front lines of the COVID-19 pandemic, not only treating patients but also educating them about the disease, tracing their contacts, and providing self-isolation advice. Nurses in this exciting profession can engage directly with communities to educate people and provide them with the skills they need to make their lives better.
