A second Texas patient has tested positve for Ebola in preliminary testing released early Sunday, Newsradio 1200 WOAI reports.

  Texas State Health Commissioner Dr. David Lakey said in a statement released early today that the patient is a health care worker at Texas Health Presbyterian Hospital in Dallas, the same hospital where Thomas Eric Duncan died of Ebola last week.

  Lakey said health officials have interviewed the patient and are identifying any contacts or potential exposures.  People who had contact with the health care worker will be monitored based on the nature of their interactions and the potential they were exposed to the virus.

  "We knew a second case could be a reality, and we have been preparing for this possibility," Lakey said.  "We are broadening our team in Dallas and working with extreme diligence to prevent further spread."

  He says additional testing will be done by the Centers for Disease Control, but the Dallas patient would be the first American to test positive for Ebola who has not been to West Africa.

  Lakey stressed again that Ebola cannot be spread through casual contact, and can only be transmitted through direct contact with bodily fluids of a sick person or exposure to contaminated objects such as needles.
