DALLAS (AP) -- The man being treated for Ebola in Dallas is now listed in critical condition.
Texas Health Presbyterian Hospital Dallas isn't providing any further details about Thomas Duncan. The hospital previously said Duncan's condition was serious but stable.
Health officials say they are monitoring about 50 people for signs of the deadly disease who may have had contact with Duncan, including nine who are believed to be at a higher risk. Dr. Tom Frieden, the director of the Centers for Disease Control and Prevention, says those being monitored include people who rode in the ambulance that took Duncan to the hospital before his diagnosis.
Duncan arrived in Dallas on Sept. 20 and fell ill a few days later. After an initial visit to the emergency room at Texas Health Presbyterian Hospital, he was sent home, even though he told a nurse he had been in disease-ravaged West Africa. He returned to the hospital last Sunday, and has been kept in isolation ever since
