Robin Roberts Falls Ill, Hospitalized During Vacation

After making a remarkable recovery and appearing back on "Good Morning America," Robin Roberts has again been hospitalized. Roberts assured fans that she is feeling "much better "and will be back on TV next week.

"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. Seems my young immune system needed a little boost to fight off 'opportunistic infections,'" Roberts posted on her Facebook page.

"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. I'm feeling MUCH better, and will relax at home for the rest of the week. I'll be back on GMA next week… as my sweet momma would say: 'Good Lord willing and the creek don't rise!'"

Roberts underwent a bone marrow transplant in September, after being diagnosed with myelodyspastic syndrome (MDS). It was a complication resulting from the treatment she received for breast cancer. During that time, Roberts received an outpouring of support from fans, and upon her return to "Good Morning America," she received one of the most heralded welcomes.

Fans have expressed their continued support for the star while she recovers.

"So glad you are doing 'ok.' I haven't been able to catch the beginning of GMA so did not know where you were… you are in my prayers and looking forward to see you back on GMA soon!" Margaret Deleo posted on Facebook.

"Take your time and heal, we all will be praying and you'll be back on your feet in no time," added Lois Hoyle.

Roberts is "the most-liked host on any American morning news show by a wide margin," The New York Times reported, based on research.
