"Good Morning America" anchor Robin Roberts spent Thursday and Friday morning at home, following doctor's orders.
Roberts, 52, posted on Facebook that she must stay home to recover from an infection. She is expected to return to GMA next week.
Roberts underwent a bone marrow transplant in September and returned to the show in February.
Doctors have been treating her for a rare blood disorder known as myelodysplastic syndrome, or MDS.
Roberts was also off the air for a short time a couple of weeks ago after falling ill while on vacation.
She posted on Facebook that the viruses are under control.
"I feel better than I have in a long time," Roberts posted on Facebook. "Going to follow doctor's orders and take the rest of the week off."
