A setback for GMA's Robin Roberts. She got an infection and landed back in the hospital.
Roberts revealed the news on her Facebook page: "Last week, in the middle of my Key West vacation, I began not to feel well. Nothing serious, just under the weather."
Doctors say her immune system is working overtime after her bone marrow transplant. She says she'll return to GMA next week.
"I'm feeling much better, and will relax at home for the rest of the week," said Roberts.
