The third case of Ebola in Dallas has been confirmed after a healthcare worker on Wednesday tested positive for the deadly virus.
The healthcare worker is the second person to be diagnosed after treating the first patient, Thomas Eric Duncan, in the United States to be diagnosed with Ebola.
The Texas Health Presbyterian Hospital worker, who was not identified, has tested positive for the disease, the Texas Department of State Health Services said in a statement on Wednesday.
The worker was immediately isolated after reporting a fever on Tuesday, the department said.
"Health officials have interviewed the latest patient to quickly identify any contacts or potential exposures, and those people will be monitored," the department said.
The news comes just days after another nurse, 26-year-old Nina Pham, became the first person infected by Ebola in the United States while caring for Duncan during much of his 11 days in the hospital. He died on Oct. 8.
The U.S. Centers for Disease Control and Prevention said in a statement that it was performing confirmation testing of Texas' preliminary tests on the new patient.
"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.
