A nurse in Texas is the first person believed to have contracted the Ebola here in the U.S.
A 15-person Hazmat crew spent the day at her apartment, scrubbing it inside and out with powerful chemicals and bringing food and water to a dog inside.
The nurse is said to have had extensive contact with Thomas Duncan on his second trip to the hospital when he was placed in isolation. Duncan died from Ebola last week.
Officials said the nurse did wear protective garb, including a gown, gloves, a mask and shield. The CDC said, at some point, there was a breach of protocol, but they don't know exactly what happened. They're looking at whether it could have happened as workers removed their protective gear. They're also looking into whether some of the more high risk procedures like kidney dialysis and respiratory intubation could have led to infection.
The Texas Department of State Health Services said they knew a second case of Ebola in Dallas would be a reality, but they're confident they can stop it in its tracks.
It appears at this time there's only one person who may have had contact with the nurse while she may have been infectious. That individual is under active monitoring.
The CDC said they've also notified neighbors at the nurse's apartment complex.
President Obama was briefed by phone, and the White House said the CDC will be working closely with state and local authorities to make sure hospitals have specific protocols in place for any potential Ebola cases.
