From USA Today (see Second Texas health-care worker tests positive for Ebola by Rick Jervis and Doug Stanglin):
A second hospital worker who helped care for Ebola patient Thomas Eric Duncan has tested positive for the disease, the Texas Department of State Health Services said in a statement early Wednesday.
The health-care worker, who was not identified, reported a fever Tuesday and was immediately isolated at the Texas Health Presbyterian Hospital.
In addition, 125 others are being watched for symptoms and the hospital is prepared for additional cases. The mayor of Dallas warned it may get worse before it gets better. Meanwhile the World Health Organization (WHO) called it the worst health crisis in modern times.
