Doctors in southwestern Connecticut say they are continuing to monitor the Ebola situation in the U.S. very closely following the death of a patient in Dallas.

Infectious disease doctors at Bridgeport Hospital say the man's death is not surprising because Ebola is a very serious disease.

Dr. Goran Milijovic says they have procedures and protocols in place at Bridgeport Hospital, and those will not change despite the death of the patient in Dallas. He says all hospitals are prepared so as to not be caught off guard.

Milijovic says although medicine in the U.S. is advanced, many factors can impact a patient's survival, including how soon the disease is recognized.

New layers of entry screening for travelers from Ebola-affected nations are being implemented at JFK, Washington-Dulles, Newark, Chicago-O'Hare and Atlanta international airports.
