Health officials in Texas say a Dallas hospital employee who treated U.S. Ebola victim Thomas Eric Duncan has contracted the disease. Duncan died on Wednesday after being diagnosed with the deadly virus at the end of September. 

The Associated Press reports that the Texas Health Presbyterian Hospital worker was tested for the virus after experiencing a fever on Friday. The tests came back positive yesterday evening. 

According to the Associated Press, officials say employees wore full protective gear when treating Duncan, but the Centers for Disease Control says there was a breach in protocol: 

Among the things CDC will investigate is how the workers took off that gear - because removing it incorrectly can lead to a contamination.

The Associated Press adds that CDC leader Dr. Tom Frieden said that anyone who treated Duncan could have been exposed, as well.
