Preventing Disease And Improving: The famed rural public health nursing program, a unique demonstration of the value of community health and sanitation departments in preventing disease and improving health conditions generally, began in 1912. The year 1914 marked the beginning of Red Cross lifesaving and water safety instruction. World War I brought the organization a rounded program, national stature, and popular recognition.
The disease continues to exist in Africa, Asia, Europe, and South America, and only the utmost vigilance by agents of the U.S. Department of Agriculture keeps it from invading the United States. Cattle, swine, sheep and goats, and the fresh, chilled, or frozen meats of these animals cannot be imported unless they are from countries free from the disease.
In addition to preventing the importation of infected animals, the U.S. Department of Agriculture operates a foot-and-mouth disease research laboratory on an island off the eastern coast. This laboratory is working on new and more effective means of controlling the disease if a new. outbreak should occur.
