News: Second person, nurse who treated late Thomas Eric Duncan hit with Ebola

A second health care worker at Texas Health Presbyterian Hospital who tended to Thomas Eric Duncan as he died of Ebola has tested positive for the lethal virus, and a local official said this morning that additional cases among the hospital's health care workers is a "very real possibility."

“The fight against Ebola in Dallas is a two-front fight now,” Dallas County Judge Clay Jenkins said, speaking at a morning press conference.

Authorities said they are now tracking 75 people following the second hospital worker’s diagnosis. The unidentified health care worker reported a fever Tuesday and was isolated at the hospital, authorities said.

The preliminary Ebola test was run late Tuesday at the state public health laboratory in Austin, and results were received at about midnight, authorities said. The Centers for Disease Control and Prevention has begun confirmation testing.

The woman was put into isolation within 90 minutes, and she is dealing with her diagnosis "with grit and grace," Jenkins said.

Authorities said this may not be the last case to be found among the hospital’s staff.

"We are preparing contingencies for more and that is a very real possibility," Jenkins said.

Dallas Mayor Mike Rawlings also suggested additional people may get sick.

"It may get worse before it gets better, but it will get better,” the mayor said.
