Former US president Jimmy Carter has been admitted hospital for treatment of a urinary tract infection less than a week after he left following a two-week stay.
The 95-year-old was admitted to south Georgia hospital, a spokeswoman for his charity The Carter Center said on Monday evening.
He was admitted to Phoebe Sumter Medical Center in Americus over the weekend but is expected to return home for recovery "soon," she added.
"He is feeling better and looks forward to returning home soon. We will issue a statement when he is released for further rest and recovery at home," the spokeswoman said.
Last Wednesday, Carter was released from Emory University Hospital in Atlanta after recovering from surgery to relieve pressure on his brain caused by bleeding from a fall.
Mr Carter has overcome several health challenges in recent years.
He was diagnosed with melanoma in 2015, announcing that the cancer had spread to other parts of his body.
After partial removal of his liver, treatment for brain lesions, radiation and immunotherapy, he said he was cancer-free.
A fall last spring required him to get hip replacement surgery.
Then on October 6 he hit his head in another fall and received 14 stitches, but still travelled to Nashville, Tennessee, to help build a Habitat for Humanity home shortly thereafter.
He fractured his pelvis in another fall later that month and was briefly hospitalized.
