The CDC and Texas health officials are stymied by the latest Ebola case in the state.
A female health care worker who was caring for Ebola victim Thomas Duncan was diagnosed with the disease this weekend.
Dr. David Lakey, Texas Department of State Health Services Commissioner, said they are still unsure how this happened.
On Sunday, health officials admitted they are not sure how she became infected.
The latest victim was not one of the original 48 suspects to be monitored.
