2nd worker in isolation with 90 minutes

(AP) — Officials say a second health care worker who's tested positive for Ebola was in isolation at a Dallas hospital within 90 minutes of the worker finding she had an elevated temperature.

Dallas County Judge Clay Jenkins said at a news conference Wednesday that the health care provider at Texas Health Presbyterian Hospital was monitoring herself for symptoms of Ebola. The unidentified woman reported a fever Tuesday and then was taken to isolation at Texas Health Presbyterian.

It's not clear how she contracted the virus during care she provided for Thomas Eric Duncan, the Liberian man who died of Ebola at Texas Health Presbyterian.

Authorities declined to say what position she holds at the hospital or the type of care she provided.
