Hundreds of children in the U.S. Midwest have been sent to hospital after falling sick with what's thought be a rare respiratory virus.
Symptoms resemble the common cold, but doctors say enterovirus 68 seems to be sending more children to intensive care than a typical virus, particularly those with a history of asthma.
"It has been associated with clusters of respiratory viral illness, so that piece was well known," Dr. Mary Ann Jackson, division director for infectious diseases at Children's Mercy Hospital in Kansas City, Mo., told NBC News. "But the clusters that have been seen in the past and reported have been small clusters of maybe, say, 25, 30 patients, and we were seeing that many patients in a day."
CNN reported that 10 states have contacted the U.S. Centers for Disease Control and Prevention in Atlanta for help in investigating clusters of enterovirus:
- Colorado
- North Carolina
- Georgia
- Ohio
- Iowa
- Illinois
- Missouri
- Kansas
- Oklahoma
- Kentucky
Doctors say enterovirus infections often occur in summer and fall, but are often mild.
Warning signs include diarrhea, vomiting, respiratory illnesses, high fever, red rash and irritability.
Officials are working to confirm the type of virus. Human enterovirus 68 was first isolated in 1962. It can require mechanical ventilation.
There is no vaccine or antiviral therapy available.
Doctors recommend handwashing and not sharing cups to prevent the spread of the illness.
