Final answer:
Public health nursing is the nursing field focused on the health of communities and individuals as a whole, aiming to prevent diseases, manage health disparities, and enhance community health.
Step-by-step explanation:
The type of nursing with a focus on the community as a whole and the health status of individuals as an aggregate is known as public health nursing. Public health professionals, including public health nurses, work to prevent the spread of illness and improve the health of communities. Their roles include prevention and understanding how disease spreads among populations. Equally important, they also address health disparities considering socioeconomic, cultural, and ethnic factors. Community psychologists share a similar goal, employing community-based participatory research methodologies and developing interventions and prevention strategies specifically tailored for communities to promote health equities.
