Everyone is talking about the virus that seems to be targeting children. Enterovirus D68. But what is it, and how do you prevent it from affecting your loved ones?

Enteroviruses in general, cause up to 10-15 million infections annually. But Enterovirus D68 is rare. So far, 12 states have been affected, including Iowa. Experts say it's too early to know how far it will spread.

Parents should watch for these signs in children: difficulty breathing, and the same symptoms as a severe common cold.

Unfortunately, there are no vaccines to prevent Enterovirus D68, and there isn't an antiviral drug to treat it. And as far as keeping it at bay? It's the regular advice: wash your hands often, avoid contact with those who are sick, etc.
