Public Health

Public health is known as a science and art of preventing disease, lengthen life, and endorse health through organized community efforts. These include sanitation, hygiene education, and early diagnosis, control of contagious infections, and preventive treatment, and adequate living standards. It wants understanding not only of epidemiology, nutrition, and antiseptic tactics but also of social science. In past public health measures included quarantine of leprosy victims in the Middle Ages and efforts to perk up hygiene following the 14th-century pestilence epidemics. In the United States, public health is studied and synchronized on a national level by the Centers for Disease Control and Prevention; internationally, the World Health Organization acts an equivalent role.
