Not the only way - leprosy is an infectious disease that can be passed from person to person via coughs and sneezes. I think armadillos are carriers so you may get it from touching one in the same way you could get herpes and salmonella from torts. That's why hand washing is so important after handling them - and armadillos - should the occasion ever arise.I watched one of the shows on TV like monster inside me. A teenage boy was playing with a dead armadillo. He ended up in the hospital on his deathbed. Doctors couldn't figure out what was wrong. Somehow they found out he had been playing with a dead armadillo. The boy had contracted leprosy. They say the only way to get leprosy is from armadillos.
Dont know if that's true but it was on TV.
I guess it's time to go to Google.
