Ebola survivor Nancy Writebol: Remember not to panic

Dr. Craig Spencer is battling Ebola at New York City's Bellevue Hospital. Doctors there say he has reached a tough phase in the battle, where patients often lose enormous amounts of bodily fluid and need intensive support. Nurse Nancy Writebol has been there. She survived Ebola. She also donated plasma to Dr. Spencer in hopes that her antibodies will help stop his infection.

Anderson spoke with Nancy Writebol and her husband David. She told Anderson that donating plasma is one way that she is saying 'thank you' to those who helped save her life.
