Hi, Jacob. My son, Shane, had it about 2 1/2 years ago. Luckily, it was a pretty mild case. He had the little red bumps on his feet and some on the palms of his hands. He didn't ever get any in the mouth, which can be painful for the little ones to eat and drink. It's a virus, and like you said, it will go away on it's own in about 2 weeks. After he had it, I've always made sure that he washes his hands after we've been out and about. You can pick it up anywhere. I always wipe down the grocery store carts before I use them. Many of our stores here have the antibacterial wipes available when you walk in the store. I don't really think there is much you can do about it. If he has it in his mouth, maybe stick with foods that go down easy, like yogurt, applesauce, etc.
