WASHINGTON (AP) — President Barack Obama says the U.S. monitoring of Ebola must be "much more aggressive.' He says federal health teams must respond to future cases within 24 hours.

Obama says the second case of an infected nurse in Dallas highlights the need to ramp up efforts to confront the disease that has struck West Africa and has reached U.S. shores.

Obama spoke after meeting with top Cabinet officials involved in the Ebola response both here in the U.S. and in the West African region where the disease has been spreading at alarming rates.

Obama canceled a political campaign trip to convene the session.

He said his administration is reviewing what happened in Dallas to ensure it doesn't happen again.

NEW: Ebola-stricken nurse being transferred

DALLAS (AP) — A Dallas nurse diagnosed with Ebola is being transferred to Emory University Hospital in Atlanta.

An ambulance with a crew clad in hazardous-material suits arrived at the hospital Wednesday afternoon and left for Dallas Love Field. There, aerial video showed the crew leading a person in a yellow hazmat suit and booties onto a jet.

A statement from the Atlanta hospital Wednesday said Amber Joy Vinson was being transferred to Emory from Texas Health Presbyterian Hospital Dallas.

However, a spokeswoman for the Dallas hospital declined to confirm that Vinson had been removed from the facility.

Vinson was one of the nurses who cared for Thomas Eric Duncan, who died at the Dallas hospital last week of the Ebola virus. Another nurse is in good condition receiving treatment for Ebola.
