Robin Roberts spent two days in the hospital fighting off an infection as part of her recuperation from a rare blood disease, and will take time off of “Good Morning America”(GMA) to rest.

The ABC News morning show host said she felt ill while on vacation in mid-April and was told to return to New York and go to the hospital. She’s home now, and posted on Facebook on April 18 that she’s feeling much better.

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

She’s generally worked three days a week, occasionally four. At the beginning of her return, ABC kept a potential fill-in on call at the studio in case she was feeling too ill to continue, the network said.

Roberts said doctors told her that her setback did not occur because she was working or doing too much.

“It’s extremely common, post-bone marrow transplant, to have complications,” she wrote.
“I’m blessed that mine have not been severe.”

She said she planned to be back on GMA during the week of April 22.

Roberts also wrote that her heart goes out to Boston residents.

“It saddens me that I haven’t been able to join my colleagues in covering this important story,” she said.
