measles in missouri Civil War

Although more than a thousand military engagements occurred in Missouri, disease killed over twice as many men as bullets. Infections spread rapidly in overcrowded camps. Measles, mumps, rubella, and chicken pox ran rampant, particularly among newly-enlisted soldiers from rural areas who lacked immunities from prior exposure. But even more fatalities resulted from dysentery and diarrhea contracted due to unsanitary conditions. The Western Sanitary Commission worked tirelessly throughout the war to improve conditions in camps, hospitals, and prisons. Science largely ignorant of the cause of diseases and most medications were ineffective. Malaria was the only major disease combated successfully, being treated with quinine, a drug made from the bark of the Peruvian Cinchona tree.8
