I am a Native American in the early 16-th century, and I hear about invaders bringing diseases in their wake. What can I do to heighten my chances of survival?

By Native American, I mean a person from modern Mexico or Peru.

Should I take closer attention to my hygiene, exercise to strengthen the immune system, avoid any human contact for the rest of my days?...

Could you include a location? Different locations would garner different answers. However, saying any location may break our rules.
