Public health has been defined as "the science and art of preventing disease”, prolonging life and improving quality of life through organized efforts and informed choices of society, organizations (public and private), communities and individuals.  Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The public can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of health takes into account physical, psychological, and social well-being.

Public health is an interdisciplinary field. For example, epidemiology, biostatistics, social sciences and management of health services are all relevant. Other important sub-fields include environmental health, community health, behavioral health, health economics, public policy, mental health, health education, health politics, occupational safety, disability, gender issues in health, and sexual and reproductive health. Public health, together with primary care, secondary care, and tertiary care, is part of a country's overall health care system. Public health is implemented through the surveillance of cases and health indicators, and through the promotion of healthy behaviors. Common public health initiatives include promotion of hand-washing and breastfeeding, delivery of vaccinations, suicide prevention, smoking cessation, obesity education, increasing healthcare accessibility and distribution of condoms to control the spread of sexually transmitted diseases.

The Centers for Disease Control and Prevention (CDC) is the nation’s leading public health agency, dedicated to saving lives and protecting the health of Americans. CDC keeps America secure by controlling disease outbreaks; making sure food and water are safe; helping people avoid leading causes of death such as heart disease, cancer, stroke and diabetes; and working globally to reduce threats to the nation’s health. When a national health security threat appears, CDC may not know right away why or how many people are affected, but the agency has world-class expertise to find out what is making people sick and what to do about it.

CDC is ready 24/7 to respond to any natural or manmade event. By connecting state and local health departments across the nation, CDC can discover patterns of disease and respond when needed. CDC monitors health, informs decision-makers, and provides people with information so they can take responsibility for their own health. CDC also trains and guides state and local public health laboratory partners to ensure that labs can safely detect and respond to dangerous health threats.

CDC works to strengthen local and state public health departments and promote proven health programs. Headquartered in Atlanta, CDC has a staff of more than 14,000 employees in nearly 170 occupations who work in all 50 states and more than 50 countries.

Public health works to track disease outbreaks, prevent injuries and shed light on why some of us are more likely to suffer from poor health than others. The many facets of public health include speaking out for laws that promote smoke-free indoor air and seatbelts, spreading the word about ways to stay healthy and giving science-based solutions to problems.
