The staff at Nassau University Medical Center in East Meadow ran emergency drills Wednesday to prepare for a potential Ebola case.

The drill involved patients exhibiting symptoms of the disease that has claimed the lives of thousands of people in West Africa.

President and CEO of NUMC Dr. Victor Politi said he wanted to put his staff to the test. Doctors, nurses and hazardous material workers were dressed according to CDC protocols.

During the drill, the mock patient was brought by an ambulance and transported to an isolation room by a specially trained doctor and nurse. Inside the room, a separate hospital employee monitored the activity of the medical staff. Meanwhile outside, the hazmat workers were helping the EMTs get out of their gear safely.

Hospital officials say mistakes were made during the simulation, but that's the point of the exercise.

Doctors say over the past few months, there were three potential Ebola cases at the NUMC emergency room, but all were negative.

NUMC's training session came one day after Dr. Craig Spencer was released Ebola-free from Bellevue Hospital in Manhattan. There are currently no known cases of Ebola within the borders of the United States.
