Will there be another Texas case of Ebola?

DALLAS, TX (KTRK) -- With the "real possibility" of another positive Ebola test, according to Dallas leaders, there's growing anxiety among Texas Health Presbyterian Hospital workers. Authorities told Eyewitness News 75 people remain at risk of contracting the virus after treating Thomas Eric Duncan. Duncan died from the virus last week.

Texas Health offered any one of the at-risk employees a room in the hospital. For the next few weeks, each must monitor themselves for Ebola symptoms. Hospital leaders stressed this is not medically necessary. They're acting out of precaution.

29-year old nurse Amber Vinson tested positive for the virus early Wednesday morning (read more here). By afternoon, she was on a medical plane heading to Emory Hospital in Atlanta. Vinson will receive treatment at that facility. She's listed in stable condition.
