DEAR DOCTOR K: I'm very worried about the new enterovirus I'm hearing about. What can I do to protect my kids against it?
DEAR READER: Enterovirus D68 is a virus causing an epidemic of respiratory infections. It has been spreading across the news and across the country, making some children quite ill. Infection with the virus can cause nothing more than a garden-variety cold, but sometimes it can lead to serious breathing trouble, particularly for kids with asthma or a history of wheezing.
