Ten states have asked the Centers for Disease Control and Prevention to investigate a rare virus suspected of sending hundreds of children in the South and Midwest to the hospital.
Dozens of people have been tested positive for Enterovirus EV-D68. There are more than 100 types of enterovirus, but this one is uncommon. It begins with cold-like symptoms and can cause serious respiratory problems.
The virus isn’t usually deadly, but there are fears that it could spread throughout the country.
