Community health nursing combines nursing skills with public health to promote health and prevent illness at the community level. It focuses on populations rather than individuals. The goals are to empower communities to address their own health issues, strengthen community resources, and provide services like health education, immunizations, and clinics. Community health nurses conduct home visits, run clinics, collect local health data, and link people to services. Their roles include direct caregiving, education, advocacy, and coordinating care for populations.
