The second health care worker to test positive for Ebola in Dallas traveled by air the day before presenting symptoms and being isolated, the CDC announced Wednesday.

The Cleveland Department of Public Health identified the health care worker as Amber Vinson. Officials said Vinson, a nurse in Dallas, was visiting family in northeast Ohio to prepare for her wedding.

CDC Director Tom Frieden said Wednesday the worker is currently in the process of being transferred to Emory University Hospital in Atlanta, which has previously successfully treated two American Ebola patients without the disease spreading further. She boarded a flight to Atlanta Wed. afternoon.

The revelation has raised alarm about further spread of the disease, which is transmitted through body fluids such as blood and saliva after the victim starts showing symptoms.

In response to the latest Ebola case, the White House announced Tuesday that President Obama is calling off a planned trip to New Jersey and Connecticut and instead will convene Cabinet officials coordinating the government's Ebola response.
