How do you finid the ratio of combat deaths to deaths of diseases in the civil war

The Civil War was America's bloodiest conflict. The unprecedented violence of battles such as Shiloh, Antietam, Stones River, and Gettysburg shocked citizens and international observers alike. Nearly as many men died in captivity during the Civil War as were killed in the whole of the Vietnam War. Hundreds of thousands died of disease. Roughly 2% of the population, an estimated 620,000 men, lost their lives in the line of duty. Taken as a percentage of today's population, the toll would have risen as high as 6 million souls.
