(CNN) – President Obama called a high level meeting to deal with the Ebola crisis Monday, as the deadly disease infects another American, a Dallas nurse who treated Ebola patient Thomas Eric Duncan before he succumbed to the virus last week.

The nurse has been identified by cnn affiliate WFAA as 26-year-old Nina Pham, a former Texas Christian University student. She is the first american to contract Ebola on U.S. soil.

She treated Duncan at Texas Health Presbyterian Hospital and was wearing protective gear during her "many visits" with Duncan, including a gown, gloves, mask and eye shield.
