Federal health officials have confirmed four West Virginia cases of a respiratory virus in children.
On Monday, the Centers for Disease Control and Prevention added West Virginia to the list of states affected by enterovirus 68. CDC has confirmed 175 people from 27 states have the respiratory illness.
Thirty-two samples were sent to the CDC from Calhoun, Greenbrier, Kanawha, Lincoln, Logan, Mercer, Raleigh, Wirt and Wood counties.
Mild symptoms could include fever, runny nose, sneezing, cough and body and muscle aches. People with asthma or a history of wheezing problems may experience difficulty breathing. Children have been particularly susceptible.
Only CDC and a small number of state public health laboratories can test for the virus.
The worst cases have required life support for breathing difficulties. No deaths have been reported.
