Nine residents at the Heritage Hall nursing home in Kentucky are confirmed to have a strain of enterovirus, according to local reports.

The Anderson County Health Department said more than 30 residents had shown symptoms, and five residents were sent to the hospital last week.

The respiratory illness, Enterovirus D68, has infected 160 people in 22 states as of Friday, the Centers for Disease Control and Prevention said. It is an extremely contagious respiratory illness mostly affecting mostly children and young adults. Enterovirus itself is fairly common, but the D-68 strain is a rare, easily-spread strain.

Some long-term care facilities, such as MidMichigan Gladwin Pines and MidMichigan Stratford Village, are under new precautions where only healthy people are allowed to visit.

Heritage Hall is located in Lawrenceburg, KY, which is about 30 miles west of Lexington. It is owned by Elmcroft Senior Living.
