(CNN) -- A health care worker at Texas Health Presbyterian Hospital has tested positive for Ebola after a preliminary test, the hospital said in a statement.
Confirmatory testing will be conducted by the Centers for Disease Control and Prevention in Atlanta.
Texas Health Presbyterian Hospital is where Thomas Eric Duncan, the first person diagnosed with Ebola in the United States, died on Wednesday.
"We knew a second case could be a reality, and we've been preparing for this possibility," said Dr. David Lakey, commissioner of the Texas Department of State Health Services in a statement.
"We are broadening our team in Dallas and working with extreme diligence to prevent further spread."
