This article states that 29,000 blacks soldiers died of disease during the War Between the States. Two things came to mind immediately. First the 29,000 was only USA forces, it did not include Black soldiers of the CSA. Second, thousands of soldiers on both sides died form disease. This link informs us that Well over 60 % of USA GI deaths were non-combat The % was about the same for CSA GI deaths. Thoughts?
