An adviser to Mayor Bill de Blasio says the New York City Ebola patient is in “relatively stable” condition.

Dr. Irwin Redlener spoke Friday outside Bellevue Hospital, where Dr. Craig Spencer is being treated.

Redlener says Spencer’s fiance also is hospitalized in isolation.

He said Spencer is not “out of the woods” yet, but the chances of his condition dramatically worsening are “very, very limited.”

Redlener says some Ebola patients have relatively mild symptoms and then “things get much worse.” But he strongly doubts that will happen in this case.

He said medical experts also are determining whether Spencer is a candidate for experimental treatments.

Redlener is director of the Center for Disaster Preparedness at Columbia University.
