Community health nursing is a synthesis of nursing and public health practice that focuses on promoting and preserving the health of populations. It treats populations as a whole and emphasizes health promotion, prevention, and wellness. The scope of community health nursing is broad, providing services to individuals, families, groups, and communities across all age groups. These services include home care, school health programs, maternal and child health services, mental health services, care for the elderly, and programs in rehabilitation centers, industrial settings, and public health. The overall goal is to enhance the health of communities through organized efforts such as health education, disease prevention, and management of health services.
