Despite release of American Ebola patients, fight against virus continues
Although we were graced with good news Thursday as Dr. Kent Brantly and missionary Nancy Writebol were released from a hospital after being treated for Ebola, there's still plenty experts don't know about the virus.
So the battle continues.

"Once you recover fully, there's no risk of transmission to other people," said Dr. Angela Hewlett, with the University of Nebraska Medical Center's biocontainment unit.
"They will not get this strain of Ebola again," she said.
Brantly and Writebol were treated with an experimental serum never before tried on humans. But Hewlett said there's no evidence to suggest the serum is the cause of their recovery.
"It could've been that they were going to recover regardless, and with good supportive care," Hewlett said.
With no vaccine available, the fight against the disease continues overseas.
"The outbreak is still going on in Africa; we have lots of people that travel," said Dr. Philip Smith, medical director for the biocontainment unit.
Smith likened the release of Brantly and Writebol to that of releasing a tuberculosis patient, noting that there are numerous tests and checks that have to be done before that patient would ever be let out to the public.
Smith added that even though they're out of the hospital, they'll continue to be monitored by the Centers for Disease Control and Prevention.
