A hospital closed a wing after mouse droppings were found in a ventilation duct, prompting fears they might carry hantavirus, which has killed several people in the Southwest in recent years.

The wing at the Gallup Indian Medical Center includes an eye clinic and a pediatric waiting room. It was closed Tuesday and Wednesday while workers tried to trap the mice.Deer mice droppings have been linked to hantavirus in the Four Corners area, where New Mexico, Colorado, Utah and Arizona meet.

Dr. Gary Escudero, the hospital's medical director, said the mice in the hospital are probably house mice, which are not known to carry the virus.
