The correct answer to this open question is the following.
Hernando DeSoto’s Expedition brought disease to the Native Americans. Is there a lesson to learn about diseases that we can apply to our world today?
Yes, there is a lesson.
The first one is that nobody has the right to mess with other nations.
The second one is that people have to be conscious that every part of the world has its customs, traditions, and hygiene practices and these have to be respected.
Native American Indians and Mesoamerican Indians were very clean people. They had notorious hygiene practices. To start with, they used to take a bath daily. They used the rivers to do that.
When the white Europeans arrived, they had tremendous bad hygiene habits. They were no clean people. They did not take a shower daily. And they brought with them several diseases unknown to the Indians. That is why they were not immune to those diseases. We are talking about chickenpox, malaria, smallpox, influenza, and cholera.

Vicksburg AssaultsMay 19 and 22, 1863-Two dramatic assaults occurred against the works surrounding Vicksburg, Mississippi, the key bastion that prevented Union naval supremacy of the Mississippi River. The two attacks cost the Union army 4,100 casualties and no ground gained. However, in the end, extended siege forced the garrison to surrender. On Independence Day, Major General Ulysses Grant seized the city and paroled its starving defenders.
ChancellorsvilleMay 1-3, 1863-Fought in Virginia, this battle was the third bloodiest battle of the war. Although it was a stunning Confederate success, the Army of Northern Virginia lost 22 percent of its force and one of its ablest generals, “Stonewall” Jackson, who had been accidentally shot by his own men on May 2.
