Mom, I'm done and I'm going to bed. Walter Reed died in 1902 or a burst appendix after finishing his work in Cuba on Yellow Fever (proving the hypothesis of Dr. Carlos Finley of Cuba that YF is spread by mosquitoes) in 1901. This also proved the worth of the cleanup of New Orleans by Benjamin Butler during the Civil War, but nobody paid any attention at the time.

I've learned that if a disease isn't carried by an insect it spreads by inhaling and exhaling or because people foul the water with their shit and other people ingest it.

So, to avoid disease, don't eat, drink, or breathe.
