The enterovirus known simply as EV-D68, has been making its way around the country this year. These are common viruses—enterovirus—but this particular strain is quite rare. In fact it is a cousin of polio, a long-eradicated virus. Fortunately it is not as strong as its once prominent cousin and while it can develop into severe respiratory symptoms, most children who catch it can get in and out of the hospital relatively quickly.
So far the virus has been reported in 12 states: Alabama, Kentucky, Ohio, Colorado, Utah, Kansas, Iowa, Oklahoma, Missouri, Michigan, and Georgia.
