A health care worker at Texas Health Presbyterian Hospital who provided care for an Ebola patient there has tested positive for Ebola in a preliminary test, the Texas Department of State Health Services said in a statement on Sunday. The health care worker reported a low-grade fever Friday night and was isolated and referred for testing, it said. "We knew a second case could be a reality, and we've been preparing for this possibility," said Dr. David Lakey, commissioner of the health service.
