Concept note-1: -Foreign occupiers were particularly susceptible: an estimated 16, 000 Spanish troops died from yellow fever between 1895 and 1898. At the onset of war with the United States, illness had decimated the Spanish fighting force, with 55, 000 troops out of an army of 230, 000 healthy enough to fight.
Concept note-2: -Although estimates vary considerably, as many as 50, 000 soldiers, officers, doctors, and sailors may have died from yellow fever.
Concept note-3: -Typhoid fever was the major killer of American soldiers during the Spanish-American War, running rampant through the national encampments. Every regiment in the First, Second, Third, Fourth, Fifth and Seventh Army Corps developed typhoid fever.
Concept note-4: -A little over 280, 000 U.S. sailors, marines and soldiers served in the Spanish-American War with approximately 2, 061 casualties, many of whom died from yellow fever.
Concept note-5: -U.S. Army surgeon Major Walter Reed and his discovery of the causes of yellow fever is one of the most important contributions in the field of medicine and human history.
