Robin Roberts, host of Good Morning America, is back in the hospital while on vacation in Key West.  

Roberts has been an inspirational figure since returning back to TV and has been in such good spirits lately about her health.  She wrote on her Facebook page to let everyone know that this recent health scare was nothing to worry about.  

"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.

Roberts went on to say, "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 was diagnosed with myelodyspastic syndrome (MDS) and underwent a bone marrow transplant in September. 

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