Dr. Kent Brantly, who was infected with Ebola while helping patients in Liberia, is said to be doing better as he receives treatment in Atlanta. As we noted earlier, the decision to bring Brantly, who is currently fighting for his life, back to the United States for medical care was not wholly smiled upon by the media and others. 

Nevertheless, Brantly arrived on Saturday and will soon be joined in Atlanta by another ailing American patient who was also infected while helping victims of the biggest Ebola outbreak on record. CNN reported that Brantly, while isolated, was able to visit with his family earlier this weekend:

Brantly's wife visited with him from behind a glass wall for about 45 minutes, the Samaritan's Purse representative said. Kent Brantly was described as "in great spirits and so grateful." 

On Sunday, Dr. Tom Frieden, who is the director of the U.S. Centers for Disease Control in Atlanta, said that Brantly's condition was improving.

It's encouraging that he seems to be improving - that's really important - and we're hoping he'll continue to improve."

Frieden added that it was too soon to predict whether Brantly will survive the virus, which has had a 60 percent fatality rate in this current outbreak.

Here's the entire interview, in which Frieden discusses the Ebola outbreak and the infected Americans.
