Health officials scrambled to learn how a Dallas health care worker caught Ebola at a Texas hospital where she had cared for a man who died from the deadly virus. The woman was identified Monday as nurse Nina Pham, her family confirmed. Pham, 26, became infected while treating Thomas Eric Duncan, the first Ebola patient to die in the USA. Pham, who graduated from Texas Christian University's nursing program in 2010, is the first person known to contract the disease in the USA.
