Another study evaluated contamination of the care environment (7). Investigators took 54 clinical specimens from 26 laboratory-confirmed Ebola cases. The researchers were able to isolate Ebola virus from 16 of the 54 clinical specimens, including saliva, stool, semen, breast milk, tears, blood, and skin swabs. They then took 33 environmental samples, including swabs from a stethoscope used to examine an infected patient, a bed frame, a bedside chair, a patient's food bowl, a patient's spit bowl, the floor, intravenous fluid tubing, and the skin of 3 patient attendants. None were positive. The only extracorporeal specimens that tested positive for Ebola virus were a physician's blood-stained glove and a bloody intravenous insertion site.
