During the early 20th century, many deadly diseases were constantly present (endemic) in the U.S. population. Typhoid Fever was one of those illnesses. Typhoid infection is caused by the bacterium Salmonella typhi and is present in the blood and intestinal waste of infected people. The disease is most frequently transmitted through the contamination of food and water. Symptoms include high fever, stomach pain, headache, and weakness.

a. isolation and bed rest
b. anti-viral medications, such as famiciclovir
c. aspirin or ibuprofen
