Robin Roberts recovering after another hospital stay

Robin Roberts is resting at home and off "Good Morning America" this week after another hospital stay as part of her recuperation from a rare blood disease.

The ABC News morning show host said she felt ill last week while on vacation and was told to return to New York and go to the hospital to fight off an infection. She's home now, and posted on Facebook on Thursday that she's feeling much better.

Roberts wrote, "Last week, in the middle of my Key West vacation, I began not to feel well. Nothing serious, just under the weather. I contacted my doctors and flew back to NYC. They felt it best to admit me into the hospital for a few days."

She added, "My doctors assured me that this was NOT because I was working or doing too much, too soon. It's extremely common, post bone marrow transplant, to have complications. I'm blessed that mine have not been severe."

Roberts underwent a bone marrow transplant last September to treat MDS, a blood and bone marrow disease. She was off work for five months before returning in February on a part-time basis to the top-rated network morning show.

She said she planned to be back on "Good Morning America" next week.
