A healthcare worker in Texas who was exposed to Thomas Eric Duncan has reportedly tested positive for Ebola after a preliminary test.
According to a statement released by the Texas Department of State Health Services, the person in question worked at Texas Health Presbyterian and “provided care for the Ebola patient hospitalized.”
Confirmatory testing will be completed by the Centers for Disease Control and Prevention.
"We knew a second case could be a reality, and we've been preparing for this possibility," Dr. David Lakey, commissioner of the Texas Department of State Health Services, said in a statement.
"We are broadening our team in Dallas and working with extreme diligence to prevent further spread."
Duncan, the first person to be diagnosed with Ebola on American soil, died this past Wednesday.
If confirmed, the healthcare worker's case would be the first known transmission of Ebola in the U.S.
As of Sunday morning, The World Health Organization reports that more than 4,000 people have died of Ebola during this latest outbreak.
