Thompson says all who have been in close contact with the man diagnosed are being monitored as a precaution.
"Let me be real frank to the Dallas County residents: The fact that we have one confirmed case, there may be another case that is a close associate with this particular patient," he said. "So this is real. There should be a concern, but it's contained to the specific family members and close friends at this moment."
The director continued to assure residents that the public isn't at risk because health officials have the virus contained.
USA Today is also reporting that the three paramedics and ER staff at the Dallas hospital which is treating the initial Ebola patient has been quarantined for 21 days, as has the ambulance that brought the patient to the hospital.
