In a Facebook post Thursday, Robin Roberts, the Good Morning America anchor, revealed that she fell ill last week while vacationing and required hospitalization to fight an infection. The 52-year-old recently underwent a bone-marrow transplant in September to treat MDS, a blood and bone marrow disease. 

Roberts was off work for five months before returning in February on a part-time basis to the top-rated network morning show.

The ABC News morning show host was upfront with her fans, as always, letting them know she was going to be alright, posting this message on Facebook:

"Last week, in the middle of my Key West vacation, I began not to feel well. Nothing serious, just under the weather," she explained. "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.'"

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

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

She also sent her well-wishes to the city of Boston, saying,

"My heart continues to go out to the remarkably strong people of Boston. We stand by you now and always. It saddens me that I haven't been able to join my colleagues in covering this important story."

We wish the GMA host a Speedy Recovery.
