Public health is a scientific field focused on protecting and promoting the health of people, their families, and the communities where they live and work. In general, public health professionals promote healthier lifestyles, preventive care, and harm reduction to achieve their goals.
Some roles within public health include:
- health educators
- first responders
- restaurant inspectors
- community planners
- public policymakers
- social workers
- scientists and researchers
- public health physicians/nurses
Some public health professionals work directly with individuals, such as public health physicians, while others play a more indirect role, influencing public health through policy, research, and communication. All of these roles work together to improve the health of a population, whether that entails a neighborhood, state, or entire country.
