Public health professionals protect and improve the health of the public through education, research, promotion of healthy lifestyles and by creating public policy. Public health takes a population approach to issues of health and well being and has been responsible for some of the greatest advancements in civilization. A broad and inclusive field, public health offers opportunities for students with many different interests and skills. Some of the career specialties in public health are research, epidemiology, biostatistics, environmental health, health administration, international health, community health education, and many others. Although public health specialists deal with threats such as cancer, obesity, diabetes, infectious diseases, and bioterrorism, they also educate the public on nutrition, child and maternal health, safe driving, and hundreds of other legal, educational, and public policy issues.
