Public Health is a field within healthcare that focuses on the science and medical practice behind preventing and containing injury and illness in a population. This sector is responsible for the global eradication of smallpox, a disease that killed an estimated 300 million people in the 20th century alone. Today, public health professionals continue to seek cures for cancers and diseases, including HIV/AIDS, breast cancer, and diabetes. They also work to improve the overall health of communities through research, regulation, and high-quality, accessible health care. As the world population increases, so does the number of people entering and exiting the United States – in 2013, the U.S. received 69.8 million visitors; 29 million U.S. residents travelled overseas. This, in turn, means the work of public health employees is needed more than ever to keep communities safe.
