Ebola - Update

A second health care worker in Dallas has tested positive for Ebola after caring for a patient who had the disease, the Centers for Disease Control and Prevention said yesterday.

The health care worker, from Texas Health Presbyterian Hospital Dallas, was isolated after developing a fever, the CDC said, and a preliminary test was positive for Ebola.

This infected person was one of 76 health care workers who were being monitored for symptoms of Ebola after they treated Thomas Eric Duncan, a man from Liberia who was the first person to be diagnosed with Ebola in the United States. Another health care worker in Dallas, Nina Pham, tested positive for the disease on Sunday.

"An additional health care worker testing positive for Ebola is a serious concern, and the CDC has already taken active steps to minimize the risk to health care workers and the patient," the CDC said in a statement.
