Robin Roberts moved to tears by fans' support after hospitalization

Sixty days after her bone marrow transplant, "Good Morning America" host Robin Roberts says she was "moved to tears" by the outpouring of love and support she's received from fans and family alike.

Opening up in a blog post Nov. 18 about a weeklong hospital stay for a "tune-up" -- aimed at combatting a latent virus that did not respond to medication -- Roberts, 51, reassured fans that her minor setback was normal for patients recovering from transplants like hers.

"Our immune systems usually take care of a virus like this ... but mine is only 59 days old. Physically I felt fine but being back in the hospital took an emotional toll on me," Roberts, who received marrow donated by her sister, Sally-Ann, in September, wrote in her Sunday blog entry. "I decided to look at my brief stay as a 'tune up' ... and then I would be back on the road to recovery. By the grace of God, I am!"

Returning to her New York home Friday to recover with the help of her sister, Roberts now says the virus that led to her hospitalization is now under control. "My numbers are going back up!" she happily confirms.
