It is concerned with threats to health based on population health analysis.
Public heath incorporates the inter displinary approaches of epidemiology, biostatistics and heath economics and health services, environmental health, community health, behavioral health, health economics, public policy, insurance medicine and occupational safety and health.
The focus of public health intervention is to improve health and quality of life through the prevention and treatment of diseases and other physical and mental conditions, through surveillance of cases and health indicators and through promotion of health behaviors.
Promotion of hand washing and breastfeeding, delivery of vaccination and distribution of contraceptives i.e. condoms to control the spread of sexually transmitted diseases are examples of common public measures.
Public health also encompasses essential activities/services such as;
• Identification of threats to health and assessment of health service’s needs,
• Timely collection, analysis and publication of information on access, utilization ,costs and outcomes of personal health services,
• Attention to the vital statistics of specific groups that are at higher risk than the total population,
• Collaboration to manage intergraded information systems with private providers and health benefit plans.
Diagnose and investigate health problems and health hazards in the community through;
• Epidemiologic identification of emergency health threats,
• Public health laboratories capability using modern technology to conduct rapid screening and high volume testing,
• Active infectious diseases epidemiology programs,
• Technical capacity for epidemiologic investigation of disease outbreak and patterns of chronic diseases and injuries.
Inform, educate and empower people about health issues you probably come across and even participated in health promotion and social marketing efforts in your community. This can be done through offering the following activities;
• Social marketing and targeted media public communications,
• Providing accessible health information resources at community level e.g. free mobile health screening initiative.

Research for new insights and innovative solutions to health problems, state and local health department staff might carry out health services research via many different efforts including;
• Continuous linkage with appropriate institutes of higher learning and research,
• An internal capacity to mount timely epidemiologic e.g. outbreak(investigations) and economic analyses e.g. cost-benefit studies and,
• An internal capacity to conduct needed health service research e.g. Survey design, conducting interviews and facilitating the focus group, conducting chemical trials and accessing and using public records.
