lifestyles, and research for disease and injury prevention. Public health professionals analyze the effect on health of genetics, personal choice and the environment in order to develop programs that protect the health of your family and community. Public health focuses on protecting entire communities or populations, rather than the individual. These communities can be small or large. This science field has a focus on improving the health of populations through education or sharing information, researching disease and injury prevention, and through encouraging healthy lifestyles. Developing methods to prevent the reoccurrence of health issues through implementing policies and educational programs is a main focus of the public health field. This is different than the traditional field of medicine that typically addresses patients after they become injured or sick.

There is a wide assortment of specialties within the field of public health. Some of the main areas include:

Environmental health

Environmental health is concerned with the interactions between our surroundings and our health and how to reduce risk factors. Examples of how environmental factors can affect the health of communities, consider food poisoning, cancer, and asthma. Areas of concern in this field are radiation protection, solid waste management, air quality, hazardous waste management, food protection, water quality, housing quality, and noise control. Individuals with a background in engineering, toxicology, and chemistry are needed in this area of public health.
